I love observing nature through the changing seasons both in my Norfolk wildlife garden and the surrounding countryside. I blog about wildlife gardening as well as about Norfolk butterflies, wildflowers and other flora and fauna that I come across.

The Acorn and the Jay

An Eurasian Jay holding an Acorn in its beak about to bury it in the grass (photo taken through a glass window).

Earlier this month I had a wonderful encounter with an Eurasian Jay that was busy burying an acorn, which got me curious about the relationship between the two.

We've had Oak seedlings pop up in our garden before, which, in the notable absence of Grey Squirrels, almost certainly had to have been planted by Jays, but I had no idea of the importance or complexity of the relationship between the two species.

The Eurasian Jay has a fantastic Latin name of Garrulus glandarius, meaning "chatty" and "acorn" respectively, which is an indication just how close a relationship the bird has with Oaks and their acorns.

Jays collect and store large quantities of acorns of Quercus Oaks in a mutualistic relationship that disperses the keystone Oak species in open scrubland where the shade intolerant tree can establish itself well, even choosing the largest most viable acorns. An estimated 2,200- 5,700 acorns are "scatter hoarded" in this way during autumn.

The Jay, a highly intelligent member of the Corvid bird family, then utilises vertical structures nearby to remember the location of approximately 75% of its cache, leaving around 25% of the acorns to germinate. Jays are only able to find acorns they've cached themselves or observed another bird caching.

Jays are believed to prefer the most nutritious acorns, selecting large acorns of Quercus ilex, Quercus suber, and Quercus faginea, whilst avoiding acorns from Quercus coccifera. Quercus ilex acorns having the highest fat content while Quercus coccifera acorns contain the most tannin of the four species.

In my case the acorn was cached 77 yards / 70.4 metres away from the parent tree, which corresponded well with research I found on their scatter hoarding behaviour. In one two year study dispersal distance ranged from 3m to 456m from the parent tree, with most acorns cached less than 100m from the source Oak.

Jays seasonal foraging behaviour further helps the Oak in that they hunt acorns least during the acorn's sensitive early spring germination phase. Jays then resume acorn hunting more intensively during May to July once it has offspring to feed. When a Jay comes across an Oak seedling growing in a spot where they recall caching an acorn, they will uproot the young plant, eat the acorn, and then crudely replant it, which the seedling usually survives.

Thanks to the Jay's important role in the spread and renewal of keystone Quercus Oak tree species in the landscape they have become known as "ecosystem engineers". One Swedish study even attempted to calculate the replacement cost of the oak planting "ecological service" that Jays provide for a particular municipal parkland area.

A Marauding Devil's Coach-horse

It seems Halloween came early to Nar Cottage this year, with the arrival of a maurading Devil's Coach-horse, and a poisonous Brown Roll-rim toadstool!

Devil's Coach-horse beetle, Ocypens olens

The Devil's Coach-horse, Ocypus olens or Staphylinus olens, is the largest of the Staphylinidae or Rove family of beetles, unsurprisingly so-called because they are always on the move. This is the largest beetle family with around 63,000 species worldwide and 1000 in the UK, making up roughly 25% of British species.

Devil’s Coach-horses are common and widespread in the UK. They are native to the UK and Europe, but introduced to parts of Australasia and America. I remember them being called a Devil’s footman in my childhood, one of many alternative names for them, but the main English name of Devil’s Coach-horse name has been firmly in use since 1840.

Although generally nocturnal, they can sometimes be seen during the day hunting for food and, due to their large size (they can grow up to almost 3cm) and striking appearance are very hard to miss! They reproduce in autumn, so it's very possible this individual was busy seeking a mate.

Their appearance is undeniably eerie, they have disproportionately large powerful mandibles for their size, an elongated jet black body and a shortened wing-case. Although they can actually still fly they rarely do so, preferring to hunt on foot. You could certainly imagine them in a fairy tale playing the role of sinister Coach-horses pulling along a fantastical evil overlord in a dark alternative to Cinderella's pumpkin-chariot.

They are indeed ferocious predators, hunting slugs, caterpillars, worms, spiders, woodlice, other invertebrates and carrion. They prefer damp places and will shelter under rocks, logs or leaf litter during the day. The female lays eggs singly in Autumn under damp moss or leaves. The resulting larvae are as carnivorous as their parents and grow through 3 instar (larval stages) over 150 days before pupating and emerging just over a month later in adults form. Devil’s Coach-horses are largely active April through to October. Adults overwinter either by staying active or by hibernating and can live up to two years.

Aggressive “Scorpion-like” Defensive Posture

They have a deservedly pugnacious reputation, mine was right out in the open in broad daylight marching around fearlessly. They are notorious for curling up their abdomen and opening their mandibles in an agressive, scorpion-like defense pose when threatened, presumably to appear large and threatening, as they aren't actually venomous and don't have a sting.

When threatened, the Devil's Coach-horse beetle, Ocypens olens, arches its abdomen in a "Scorpion" style defensive posture, opens its jaws and secretes a foul liquid from its glands

Another defense mechanism is the ability to emit a noxious substance from white glands on their abdomen, which the second half of their binomial name, olens, meaning "smelling", alludes to. If further threatened, their strong jaws can also give a nasty nip.

Devil’s Coach-horse in Folklore

They've been associated with magic, evil forces and the Devil in British superstition and folklore since mediaeval times. One theory is that the name developed in parallel with Ladybird (derived from Our Lady, referring to the biblical Mary) and was established by 1840. Other English names include Devil's coachman or footman and Devil's steed. In Irish they are called "Darbh-daol" devil's beetle and "Coffin cutter". There are a host of dark folklore superstitions surrounding Devil’s Coach-horses, which hasn't exactly helped their reputation.

In some superstitions, as well as being directly associated with the devil himself, they are purported to have eaten the core of Eve's apple and to even have acted as a kind of beetle form of Judas Iscariot and have arched its abdomen to point the way Jesus went during his betrayal. They were also believed to be endowed with magical powers and that when they arched their tail towards someone they were cursing them.

In Ireland it was even believed the beetle could strike a person dead on sight and would eat any sinners they came across. Sadly as a consequence some superstitions rewarded killing them. Although some scythers would put one in their scythe handles to improve their skill (or perhaps speed given their nasty bite!).

Gardening Value of the Devil’s Coach-horse Beetle

Despite their fearsome appearance and agressive defensive mechansims, they do get an unfairly bad rap. Devil's Coach-horses are in fact highly valuable insects to have in the garden and act as a “Gardener’s friend” by hunting garden pests like slugs and caterpillars. In fact one of the Devil’s Coach-horse’s smaller cousins in the Rove beetle family, Atheta coriaria, is even used commercially as a form of biological pest control against certain greenhouse insect pests, including fungus gnats, shore flies and thrips.

Wildlife Value of the Devil’s Coach-horse Beetle

Through their role as a dominant predator species in their niche, they provide eco-system benefits by keeping populations of potential pest species in check naturally, in addition they consume carrion and ensure that nutrients are recycled and returned to the soil.

Brown Roll-rim Mushroom

Gills of a mature Brown roll-rim mushroom, Paxillus involutus

As if that wasnt spooky enough, a large area of my garden surrounding my Birch trees has been beset by the fruiting bodies of what turned out to be a poisonous toadstool called the Brown Roll-rim.

Apparently it is notorious for being particularly treacherous. Originally boiling them was thought to remove all toxins and make them safe to eat, but it was later discovered that the mushroom held a second toxin that build up over a long time and then suddenly kill you by triggering an auto-immune reaction that causes the body to attack its own blood cells. Definitely not one for the pot!

The Fifth And Most Beautiful Season

The sight of a Common Darter dragonfly perching on Purple Loosestrife is a sure sign that autumn is just around the corner …

Its funny how you intuitively sense the turning of the seasons even before anything obvious has actually changed. Its like a little pause as nature takes its breath before things transition.

The days are calm, its still hot and sunny, storms have yet to arrive; yet things are somehow imperceptibly different. Maybe the light is softer and more golden, maybe a dew appears, maybe you notice a spiders web, or dusk arriving that little bit earlier.

German writer Kurt Tucholsky called this magical, all-too-brief hiatus between summer and autumn the “Fifth season”. Ironically, Tucholsky lived during a period of transition himself -becoming a major literary figure during the turbulent Weimar period in Germany and being one of the first writers to have books burned when Hitler came to power. I couldn’t find an English translation so I’ve attempted a rough side-by-side translation of his poem below (my German translation scores at uni were always lousy, so please forgive any linguistic clumsiness).

For me nothing evokes this “fifth season” like the sight of Small Copper butterflies dancing amongst the beautiful magenta Purple Loosestrife flowerspikes that encircle my wildlife pond, and crimson Common Darters waging their ariel battles and hovering in tandem above the water. Such a beautiful, yet ephemeral sights …

One morning you smell autumn. It is not yet cold; it is not yet windy;
nothing actually has changed at all - and yet everything has.
— Kurt Tucholsky, 1890-1935

Die Fünfte Jahreszeit - Kurt Tucholsky

Wenn der Sommer vorbei ist und die Ernte in die Scheuern gebracht ist, wenn
sich die Natur niederlegt, wie ein ganz altes Pferd, das sich im Stall hinlegt,
so müde ist es - wenn der späte Nachsommer im Verklingen ist und der frühe
Herbst noch nicht angefangen hat - dann ist die fünfte Jahreszeit.

Nun ruht es. Die Natur hält den Atem an;
an andern Tagen atmet sie unmerklich
aus leise wogender Brust. Nun ist alles vorüber: geboren ist, gereift ist, gewachsen ist, gelaicht ist, geerntet ist - nun ist es vorüber.

Nun sind da noch die Blätter und die Sträucher,
aber im Augenblick dient das zugar nichts; wenn überhaupt in der Natur ein Zweck verborgen ist: im Augenblicksteht das Räderwerk still. Es ruht.

Mücken spielen im schwarzgoldenen Licht, im Licht sind wirklich schwarze Töne,
tiefes Altgold liegt unter den Buchen, Pflaumenblau auf den Höhen ... kein Blatt
bewegt sich, es ist ganz still. Blank sind die Farben, der See liegt wie gemalt,
es ist ganz still. Ein Boot, das flußab gleitet, Aufgespartes wird dahingegeben - es ruht.

So vier, so acht Tage - Und dann geht etwas vor. Eines Morgens riechst du den Herbst. Es ist noch nicht kalt; es ist nicht windig; es hat sich eigentlich gar nichts geändert - und doch alles.

Noch ist alles wie gestern: Die Blätter, die Bäume, die Sträucher ... aber nun ist alles anders....Das Wunder hat vielleicht vier Tage gedauert oder fünf, und du hast gewünscht,
es solle nie, nie aufhören... Spätsommer, Frühherbst und das, was zwischen ihnen
beiden liegt. Eine ganz kurze Spanne Zeit im Jahre.

Es ist die fünfte und schönste Jahreszeit.

The Fifth Season - Kurt Tucholsky

When summer is over and the harvest brought into the barns, when nature lies down like an old horse that lies down in the stall,
it is so tired - when the late
days of summer are waning and early autumn has not yet arrived - that is
the fifth season.

Now it rests. Nature holds its breath;
on other days it breathes imperceptibly
from a gently heaving chest. Now everything is over: born, ripened, grown, spawned, harvested - now it is over.

Now the leaves and bushes are still there,
but in an instant that turns to nothing;
if there is a purpose hidden in nature at all: for a second the gears stand still. It rests.

Midges play in black-golden light, in the light are really black tones,
deep antique gold lies under the beeches, plum-blue in the canopy … no leaf
stirs, it is completely still. The colours are bold, the lake is as if painted,
it is completely still. A boat that glides downstream,
What is stored up is released - it rests.

So four, so eight days - and then something happens. One morning you smell autumn. It is not yet cold; it is not yet windy; nothing actually has changed at all - and yet everything has.

Everything is still like yesterday: the leaves, the trees, the bushes … but now everything is different …. The wonder has lasted maybe four days or five, and you have wished
it would never ever end…late summer, early autumn and that which lies between them both. A whole short span of time in the year.

It is the fith and most beautiful season.

Seeing Small Copper butterflies in my wildlife garden is another hint that autumn is on its way.

Butterflies and Blackthorn Blossom

Peacock butterfly, Aglais io, nectaring on early Blackthorn, Prunus spinosa, blossom

Every year I wonder when and which butterfly species will be my first sighting of the year. Often its a “classic” springtime butterfly like a Brimstone or an Orange tip butterfly, but this year it was actually a Nymph family butterfly instead.

Out of nowhere on the 17th March, a Small Tortoiseshell appeared, it landed, pausing briefly to bask on some bare earth, only just long enough for an ID then darted off in the stiff breeze.

The sighting was so fleeting, however, that it was only really when I caught sight of this Peacock butterfly, Aglais io, a week later, with is vivid diversionary eyespots, frantically nectaring on newly opened blossom on the still leafless Blackthorn branches several days in a row in my native hedgerow that I really felt that spring was finally on its way and warmer days were not too far off.

It was also a timely reminder of just how vital a habitat a mixed native hedgerow is for our early pollinators. Blackthorn, Prunus spinosa, and other early flowering Prunus species for example are particularly important both for newly emerging butterflies, bees and hoverflies as well as acting as caterpillar hosts once their leaves burst and eggs hatch.

Its often overlooked in favour of exotic non native evergreens or plain old fencing, but by the time its warm enough to spend any time in the garden my native hedge is so thick my garden’s totally private. Hopefully as wildlife gardening becomes more popular and awareness of just how bad things are for insects and the remaining wildlife that depends on them, the popularity of mixed native hedging will start to increase.

At last, it is spring!

A Painted Lady Summer

Painted Lady, Vanessa cardui nectaring on white Buddleia. Will 2019 be a record-breaking Painted Lady summer?

As the Butterfly Conservation Society’s annual three week long Big Butterfly Count draws to a close, the UK looks set to have enjoyed the magical, once-in-a-decade phenomenon called a “Painted Lady summer” when the apricot- and black-marked species arrives here en masse.

The last such event occured in 2009, when some 11 million Painted Ladies, known as Vanessa cardui, arrived on our shores and there is speculation that 2019 could be a record-breaking year.

But how is it that a butterfly that doesn’t survive our winters and isn’t even permanently resident in the UK manages to congregate here in such numbers?

The Painted Lady, a member of the large and colourful Nymphalidae butterfly family, is a poweful flyer and long distance migrant. During its migration it can achieve an impressive speed of almost 30 miles per hour and fly some 100 miles in a day. In fact, it’s 7,500 mile round trip migration from North Africa as far north as the arctic circle is even longer than that of the famous Monarch butterfly, which travels up and down the North American seabord.

Freshly emerged, second generation Painted Lady nectaring on a budding Common Knapweed flower

Despite its flying prowess, like the Monarch butterfly, Vanessa cardui traverses its intercontinental route multigenerationally and, having only a 2 week long life span, takes about 6 generations to complete it.

Each season the butterfly flies northwards from the desert fringes of North Africa to reach mainland Europe and then on to the UK, reaching Britain in late March. Here the newly arrived lepidopteran immigrant lays eggs on Marsh and other Thistles, Viper’s Bugloss, Mallow and Nettles. After about a month-and-a-half later the next generation emerges (46 days according to devoted turn of the century lepidopterist F. W. Frohawk).

These native-born Painted Ladies then lay a brood of their own, which, further supplemented by arrivals from both Europe and Scandinavia, significantily boosts numbers towards late summer. Some of these butterflies will commence the return migration southwards as the seasonal conditions turn.

So what makes the once in a decade “Painted Lady year” of mass abundance occur? Experts believe that the butterfly’s migratory instinct may be triggered by population density (leading to competition for egglaying sites and food sources) and in exceptional years, unusually good food availability and favourable weather conditions foster population booms. This in turn triggers mass North- and Easterly-bound migrations, often with hundreds, even thousands of butterflies reaching landfall along the UK’s East and South coastline, some arriving from Europe, others from Scandinavia and some even directly from Africa in favourable windstreams.

As well as Thistles for egg laying, depending on its generation, adult Painted Lady butterflies will nectar on a wide range of plants. These include Knapweeds, Buddleia, Trefoils, Hawkweeds, Heather, Privet, Ivy, Bugle and Clovers, so planting these species, and tolerating that annoying thistle or two (you can always deadhead later to stop the patch growing!) increases the likelihood of you attracting this orgeous, intricately-marked butterfly into your garden and enjoying your very own Painted Lady Summer.

Cheery Cowslips

Cowslips are invaluable to early pollinators and have a long flowering period

The mid-Spring superstar of our wildflower meadow this year was undoubtably the humble Cowslip, Primula veris. I’d always hoped to see them in my wildlife garden, as not far up the lane from my cottage is a little tucked away-clearing near a small copse that is too small to farm and in springtime always seemed to be bursting full of rich custard-coloured Cowslips mixing in beautifully with the deep indigo of native Bluebells.

Disappointingly, despite their inclusion in my native seedmix for clay soil, for the first two years not a single one materialised. I philosophically put it down to the soil conditions or an unlucky batch mix and thought I might sow some plugs another year.

Then unexpectedly, the very next spring just a smattering appeared! I was overjoyed to learn that it was simply that their seeds can take several seasons to germinate and interpreted it as an encouraging sign our meadow ecosystem was establishing itself well naturally.

Since then they’ve gone from strength to strength, spreading almost right across the small sward. They must particularly like cool dry springs as this year, our meadow’s sixth season, has been their best appearance to date.

Wildlife Value of Cowslips

Aside from their cheerful colour and long lasting flowerheads, they have a healthy wildlife value. Their flowers are a vital resource for pollinators, particularly for early solitary bee species, quite a few of which frequent our garden, but also for butterflies such as the Brimstone butterfly and other insects such as beetles. They are also the caterpillar plant for the Duke of Burgundy butterfly, which is unfortunately not resident in Norfolk.

A member of the Primula family, the Cowslip shares more than a passing resemblance to it's cousins the Primrose Primula vulgaris and the Oxlip Primula elatior, however both of these lack its pleasant apricot perfume and have more open paler lemon-hued flowers.

Plant Folklore of Cowslips

Cowslips can take several years to establish in a new meadow

Amusingly the Cowslip’s latin name Primula veris romantically deems it the “true” primrose, while its established English name more, ahem, rustically refers to its habit of growing near “cow’s slops” or cowpats in grazing pasture. It does have over two dozen pleasanter names in traditional folklore including other farming references such as Milk Maidens, descriptive names such as Freckled face, Golden Drops and Long legs as well as biblical names mentioning Mary or alluding to a myth that Cowslips sprang up where St Peter dropped the keys to heaven, perhaps in a cow pat!

Cowslips’ varied folklore names include: Artetyke, Arthritica, Buckles, Bunch of keys, Crewel, Drelip, Fairy Cups, Fairies' flower, Freckled face, Golden drops, Herb Peter, Hey-flower, Paigle, Peggle, Key Flower, Key of Heaven, Lady's fingers, Long legs, Milk maidens, Mayflower, Mary's tears, Our Lady's Keys, Palsywort, Password, Petty Mulleins, Plumrocks, Tisty-tosty. Welsh: dagrau Mair meaning Mary's tears, Anglo-Saxon: Cuy lippe, Greek: Paralysio.

The Cowslip has a rich cultural and culinary history too; traditionally it decorated Mayday garlands and was strewn along churchyard pathways at weddings and religious festivals. The Cowslip was used medicinally to aid sleep and heal coughs as well as to make Cowslip wine and “Tisty-tosty”, little balls of crushed up Cowslip flowers.

In the literary world the Cowslip’s honours include mentions in Shakespeare’s “The Tempest” and “Henry V” plays as well as featuring in Keats’ poem of Springtime romance “Hither, hither love”.

Hither, hither, love —

‘Tis a shady mead —

Hither, hither, love!

Let us feed and feed!

Hither, hither, sweet —

’Tis a cowslip bed —

Hither, hither, sweet!

'Tis with dew bespread!

Hither, hither, dear —

By the breath of life —

Hither, hither, dear!

Be the summer’s wife!

Though one moment’s pleasure

In one moment flies —

Though the passion’s treasure

In one moment dies —

Yet it has not passed —

Think how near, how near! —

And while it doth last,

Think how dear, how dear!

Hither, hither, hither

Love its boon has sent —

If I die and wither

I shall die content!

John Keats









And Breathe... Spring is here!

Just when you think you really can’t take it any more, finally the temperatures drift up, the first Blackthorn blossom appears in the hedgerows on still naked stems and you know that Spring, at long last, is here.

February Gold and a Fool's Spring

With the synthetic cheer of the twinkling fairy lights of Christmas in the dim and distant past, the long dark trek to springtime always feels like a brutally hard slog.

The ground seems stark, barren and lifeless. Yet all the while beneath the surface plants and trees are quietly, imperceptibly getting ready to burst out from their winter buds.

Catkins, male flowers of many common native shrubs and trees such as Hazel (Corylus avellana) and Birch trees (Betula pendula) are among the earliest augurs of that yearned for spring. As the days rapidly lengthen, golden evenings start to appear, bathing the delicate, golden chains of late winter catkins in beautiful light.

In contrast to the deep chill and bitter Beast from the East last year, winter 2019 has been remarkably mild. This February has even proven to be the warmest one on record thanks to a brief flurry of sunny mild days that heartened us all with a tantalising promise, however fleeting, of warmer days to come. One mild evening in mid-February I took advantage of the rich late afternoon light during our "fool's spring" to do a little study of the Hazel and Birch tree catkins in my garden.

I learned that branches carry both male and female flowers with the male catkins emerging first. Hazel trees carry tiny little female red flowers that emerge soon after higher up the branch stem, whereas Birch trees have small, bright green, upward curving female catkins.

Catkin pollen is intended to be windborne to pollinate other trees, there being so few insect pollinators about at the time of year, so it has evolved to have a self-repelling quality meaning that bees and other insects struggle to collect much of it, although it is a food source for them at a time of scarcity.

Despite the luscious hue of light, the days rapidly turned back to chilly ones with even our fool’s spring warmth quickly forgotten. But soon, soon true Spring will burst forth in her lush green finery and the late winter gold fade out of memory.

Smoothly Enters the Newt

A surprising number of tadpoles survived this year's late snow and frosts to hatch out, proving that nature has long coped with such seasonal extremes. Once hatched, a tadpole's lot does not get easier by any means, because along with the warmth, their nemesis the Common newts have returned.

Common newts, also known as Smooth newts, predate heavily on tadpoles and frogspawn in springtime, and male Common newts can be spotted due to their vivid orange and black spotted underbelly which is a temporary colouring worn during the mating season.

The Beast from the East

Winter definitely had a vicious sting in its tail this February. A "sudden stratospheric warming" over the North Pole, in itself disturbing at this time of year according to climatologists, caused a sharp cooling in lower levels of our atmosphere and via a complex chain of meteorological events reminiscent of the metaphor about the butterfly that flapped its wings on one continent and caused a hurricane on another, brought about heavy snowfall that covered virtually all of the British Isles.

An unusually strong and harsh northeasterly wind stream dubbed the "Beast from the East" triggered a bitter cold snap then swept in heavy snowfall, which was in turn intensified by strong drifting due to the fierce, biting winds that blew continuously for days. 

Here in big sky Norfolk we were heavily exposed to "the Beast" and much of the county was cut off by incredibly large snowdrifts formed by its winds. These, I noticed, were far deeper in areas where the farmers' field verges lacked hedging, a stark reminder of the environmental value of this oft overlooked habitat, which for many years was ripped out to maximise the yield potential of the land in ill-conceived agricultural efficiency drives.

Thankfully many incentives now exist for re-establishment of these vital wildlife corridors and natural windbreaks, so hopefully Norfolk will improve its reputation among hedge layers in years to come.

First Snowdrops

In past years, its been February before I've visited Hoe Rough to enjoy the snowdrops there out in force. But this year my first snowdrop sighting at one of my favourite, peaceful nature reserves was much earlier than usual, on the 16th January.

Almost all the snowdrop plants were still quite stubby and offering just the tiniest glimpse of little furled up white buds, there were just 2 or 3 well positioned snowdrop clumps that had opened. So for the first time I captured the very first flush.

In The Snowdrop and the Honeybee I explored the natural history and folklore of one of our earliest flowering wildflowers. Native or not, your heart can't help but lift when you first see Persephone's favourite little flower return from the depths of the underworld to a barren frosty landscape, reminding us that spring may not be as far away as it feels. 

Festive Frost

Frost covered leaf litter

December has been colder than in recent times and we've had not a few chilly, white-world frosty mornings of late.

Hoar frosts have always held a special place in my heart as they always take me right back to fond memories of frozen winter wonderland walks up on the Ridgeway back in Letcombe Regis, but what makes a Hoar frost so special?

A Hoar frost, also known as hoarfrost, pruina or radiation frost, occurs on cold, clear nights with humid air when a dew would form if it were warmer.

In a Hoar frost, leaves, grass, branches and other objects cool by radiation to well below frost point, allowing water vapour to condense directly in the form of ice crystal deposits rather than in the form of water droplets first.

A normal White frost or Ground frost is caused when water vapour from the air forms a liquid dew first and then freezes with a subsequent drop in temperature, so tends to be more globluar in shape rather than feathery or crystalline. Fog tends to inhibit Hoar frosts as it prevents radiation cooling, however can create Rime, which is an ice deposit formed from supercooled fog vapour that crystallised when it touches a frozen object.

In Search of Autumn...

Our mellow autumnal weather seems to be both treating and playing tricks on us this year.

Mingled gold and green birch leaves

As mid October arrived I started to search for turning leaves and classic signs of Autumn, but in vain. With such mild temperatures, the trees have determinedly held on to their cloaks of green as long as possible to maximise their intake of food.

A Stroll in Blickling Estate at the start of half term week yielded some fallen leaves but the canopy was disappointingly still richly decked in a gown of glorious green, with only the occasional tree starting to offer up a hint of gold at the very top of their crowns.

At last on a visit to Wells-Next-The-Sea at the end of the week, the mood had started to shift and begun to evoke a more autumnal tone. A gorgeously mild day, I watched several Red Admirals dancing brightly in the deceptively warm golden rays of the afternoon sun, but at last, I finally saw my first fully golden-gowned birch tree!

Meanwhile, further along the pathway, a suitably russet-hued Common Darter dragonfly cast a long shadow as it perched on a fallen pine introducing rich red umber tones to the Autumnal palette. 

Phew! - our tardy Lady Autumn really has finally arrived with her gown of gold, just in time for the clocks to go back.

A Purple Streak

The colour purple became my leitmotiv during early July. It is the season of the purple butterflies and therein lies a tale of mystery and obsession...

The Oak tree canopy is a habitat for both Purple Emperor and Purple Hairstreak butterflies, which both feed on aphid honeydew

The Oak tree canopy is a habitat for both Purple Emperor and Purple Hairstreak butterflies, which both feed on aphid honeydew

Two very different, yet equally enigmatic, purple butterfly species are on the wing towards the end of June into mid-July. Though very different in fame and stature, both share two things in common: a fondness for the heady heights of mature Oak tree canopies in deciduous woodland and a strong reputation for elusiveness and ability to evade the gaze of even the most determined of butterfly seekers.  

Since being drawn into the world of butterflying I've discovered that, since time immemorial, avid butterfly chasers have gone temporarily a little doolally at this time of year. The hysteria is all over a certain famous, purple-cloaked member of the royal family who is not, officially at any rate, currently resident in Norfolk - the magnificent Purple Emperor. 

Known affectionately to his acolytes as "his Majesty" or sometimes simply "Iris", the Purple Emperor is neither Britain's largest butterfly (our very own Norfolk Swallowtail),  nor the rarest (the once extinct, recently reintroduced Large Blue), nor even the brightest (arguably the Silver-washed Fritillary) so this seemingly bizarre Purple Emperor obsession had been puzzling me for some time. Just what quality is it that bewitches them all? Is it the dramatic colour purple? Their reputed vigorous flight and aggressive behaviour? Or some other mysterious factor altogether ....?

After an inspiring talk by renowned butterfly conservationist and Purple Emperor advocate Matthew Oates at Norfolk Butterfly Conservation's AGM back in 2016, I became intrigued and not a little bewitched myself. In a bid to sate my curiosity and discover the obscure reason for the Purple Emperor's celebrity status for myself, I started planning a field trip to visit his Imperial Majesty's haunts, mature Oak and Sallow woodland rides.

Alas fate was not on my side,  despite attempts to make visits to Fermyn Woods in Northants, Wood Walton Fen in Cambridgeshire or Theberton in Suffolk, life events have intervened and scuppered my plans well and truly for this year. Perhaps Iris is to be my new five year nemesis butterfly, who knows. 

With my ability to range much curtailed, I was crestfallen and deeply disappointed. But there was still the second less famous, but to me equally elusive, purple butterfly to discover: the Purple Hairstreak butterfly, Neozephyrus quercus. And it lives much closer to home.

Although much smaller, the Purple Hairstreak butterfly shares a surprising number of characteristics in common with its larger Imperial cousin. As suggested by its Latin species name "quercus" it too favours mature deciduous oak woodland and so is also highly elusive (and under-reported) as a result to its habit of dwelling up high amongst the tree canopy. There it lives on honeydew produced by aphids and only rarely descends from the "throne" for the odd sip of bramble nectar.

While laid up I did my research thoroughly. Purple Hairstreaks being far more widespread than his majesty, I was able to find some promising local locations in Norfolk, and had in fact already experienced my first brief glimpse of a old faded and tattered Purple Hairstreak on a dog walk at Holkham Hall one August a few years back. I took a punt on a very short run up to the nearby Syderstone Common nature reserve,  on the edge of North Norfolk coastal AONB. Its a large reserve of lowland gorse heathland, an SSSI that is famous for its Natterjack toad population, but not all that much else, in fact a previous visit had left me visually underwhelmed. This time however the reserve was transmuted into a spectacular sea of vivid fuchsia pink willowherb flowers swaying in the gentle breeze.

My fieldcraft skills must have improved somewhat as I was delighted to spot an active Purple Hairstreak quite soon into my visit. There it was, a small grey blob fluttering away right up high in the treetops, initially silhouetted against the cloudy sky. Its flight was erratic and it was hard to keep track as the butterfly flitted amongst the oak treetop and nearby birches in the mature woodland circling this now spectactularly beautiful reserve.

After spotting my Hairstreak's "Master" Oak I stayed for some time, craning my neck to try to spot this diminutive butterfly amongst the oak leaves. Eventually one dropped a little lower and permitted a quick shot before circling up high again in a cluster of nearby Birches.

On my way back to the car I spotted a beautiful young buck Roe Deer, who paused, checked me out for a little while then barked at me before trotting off back into the Oak woodland, a beautiful end to my successful visit. Although my sightings had been distant and tantalising, I had bagged my first purple.

Perhaps the abiding memory for me is not so much finally photographing my first purple butterfly, but rather Syderstone Common nature reserve itself, which was a natural habitat at the peak of its mid-summer glory and afforded a sensory firework display of wildflower delight at every turn.

Visually the abundant vibrant pink Rosebay Willowherb flower spires intermingled with creeping carpets of rich yellow Tormentil, while the heady scent of rambling native Honeysuckle hung in the air and bramble in full bloom. Every plant seemed to be alive, swaying in the breeze and dancing with a host of orange Skipper, Ringlet and Meadow Brown butterflies flitting about into the distance as far as the eye could see.

As for purple Royalty... I must now be patient, wait and bide my time till 2018 brings a whole new season and fresh opportunity for his Imperial Highness to ensnare me as subject.

We shall see...

A Celebration Of Diversity

In the week that saw the Pink Pride parade in London that celebrated 50 years of progress towards greater acceptance of human diversity, I was celebrating different kind of diversity success on a much smaller scale in my back garden -  the biodiversity success of wildflower varieties in my wildlife flower meadow surrounding our pond.

In its fourth flowering season, the Nar Cottage wildflower meadow project has finally come into its own and is becoming a mature, established bio-diverse habitat. At last pinks, purples and mauves of Tufted Vetch and Knapweeds intermingle generously among large clusters of yellow Bird's-foot trefoil, and have started to balance out the till now prevalent whites of Ox-eye daisies and Yarrow which had dominated the last two seasons flowering. A real "purple streak" of wildflower diversity you could say.

The meadow is noticeably lower than the past two seasons and the dry spring and early June heatwave may have contributed to the increase in biodiversity as different plants definitely either struggled or thrived in contrast to the previous two colder and wetter seasons. In addition, Yellow rattle has established itself very well this year and should continue to weaken the competitive grasses in future years.

Every year the flower mix in the meadow evolves and changes to puts on a unique display of meadow flora and fauna. It will soon be hay cutting time, but already I cant wait to see what next year's meadow will be like.

Of Yellow Flags and Swallowtails

In an unprecedented week that saw the president of the largest Western Great Power turn his back on the Paris Accord to reduce emissions causing global climate change, I took advantage of ironically hot, sunny weather to visit Strumpshaw Fen RSPB Nature Reserve to see one of the UK's rarest and most threatened butterflies, the British Swallowtail, Papilio machaon britannicus.

The trip was an impromptu reprise of my longstanding attempts to enjoy watching this beautiful endangered Norfolk butterfly, which inspired a earlier blog post on my misadventures over several unsuccessful seasons attempting to find them at various Norfolk nature reserves. Last year, I was even interviewed as part of a BBC OneShow item on the native Swallowtail covering the story of a much more famous lepidopterist's longstanding desire to see them.

This time I was hoping for more than a record shot of this rare and uniquely beautiful butterfly, one of only 6 butterfly species fully protected by UK Law since 1992. With the weather so fair sightings had been good all week so I was daring to hope for some natural behavioural shots of it amongst native fenland flora and habitat, rather than perched upon the pretty Sweet William in the renowned Doctor's flower garden.

After a pleasant chat with a Welsh couple now close to completing a multi year hunt to see all of Britain's 59 native species, I had not  ventured far into the reserve before I enjoyed a wonderful encounter of a freshly emerged Swallowtail first basking low down then fluttering up with its ghostlike flight pattern onto a nearby patch of deep yellow flag iris flowers where it began to nectar frenetically. Then the inevitable happened. It was after all Strumpshaw Fen, a sunny Sunday and Swallowtail peak season: The Lepidopteran papparazzi descended.

Within minutes a host of papparazzi lenses, many far too short for the purpose, had surrounded the poor butterfly and their owners, caught up in the viewfinder, became oblivious to both other nature observers as well as the butterfly's wellbeing, and lens hoods started to encroach within inches of where the butterfly was attempting to feed up, blocking out both light and other people. I gently chaperoned and chastised as best I could to create space for the butterfly to feed and all to take turns to see, before moving on frustrated as the crowd grew too big and closed in again around the butterfly.

I reflected on how , perfectly polite people, behind the viewfinder in focussed pursuit of the perfect digital trophy shot, rapidly became so blinkered and oblivious as to unwittingly block our others and even potentially disturb the rare and protected creature they had come to see. I speculated how many had walked right past numerous other fascinating wildlife and flower species without really stopping to enjoy and appreciate them, in their single-minded mission to capture the one famous "celebrity" species. It prompted me to question the drivers behind my own past mission too, though my long lens's minimum focus always helps ensure a respectful distance.

On a bigger scale, it made me contemplate whether charities' tendency to focus on preserving single "blue chip" star species (using gallons of pesticides in the process) rather than untouched habitats is more a help or a hindrance in our efforts to help environmental recovery.

Thinking back to the Paris Accord. I wonder whether it will ultimately ever really be possible for us, collectively as the human species, to overcome our ingrained survival instinct of self interest to do "the right thing" on a big enough scale in time. I hope so. If not, then perhaps our nation's own beautiful custard-yellow Swallowtail sub-species truly is already the ghost it sometimes appears to be, fluttering amongst it's beloved milkweed and flag iris.

The Snowdrop And The Honeybee

The sight of this little Honeybee gratefully nectaring among the first of our Snowdrops in a local reserve made me curious about this humble little late winter flower and I discovered it had a surprising and fascinating history.

Gardening Value of Snowdrops

By February we are all utterly weary of winter's leaden skies and lashing storms and desperately seeking those first subtle signs of spring, so it comes as no surprise that Common Snowdrops, or February's Fairmaid as they are sometimes called, are such popular flowers and a staple in British gardens. It is a heavy heart indeed that could not be lifted by the sight of a milky white snowdrop flower head as it nods cheerily in the soft sunlight of a mild winter's day, or bravely peering through a late winter snowfall to earn their French name of "Pierce-neige" or Snow Piercer.  

Snowdrops favour damp woodland and stream side habitats

There are about 20 species of Galanthus in all, with the name Galanthus nivalis stemming from the Greek gala and anthus "Milky flower" and the Latin nivalis meaning "Snow".

It spreads primarily by bulb division into a dense white carpet which can form uplifting winter displays and many parks and gardens where it is long established, such as West Lexham Estate and Walsingham Abbey in Norfolk, open annually to allow visitors to enjoy their beautiful displays.

Wildlife Value of Snowdrops

For our over-wintering wildlife, the sight of a Common Snowdrop is undoubtedly very lucky indeed and a massive boon at a time of great hardship and need. Their flowers provide a desperately needed source of nectar and pollen for early insects such as queen and solitary bees emerging from hibernation, as well as beetles and flies.

In addition, their seedpods, which contain protein-rich elaiosomes, are taken by ants and fed to their larvae in undergrouund tunnels. By so doing, the ants complete the circle of life by helping the Snowdrop plant’s seeds disperse and start new colonies nearby.

Is the Snowdrop a Native Flower?

Fond of damp woodland and watercourses, many people mistakenly believe that the Common Snowdrop is truly native to Britain or introduced in Roman times, as did I until I researched this article. In fact, Snowdrops were first recorded in John Gerard's 1597 edition of "Great Herball" and they were documented in the wild only in the late 1770's. It is now believed Galanthus nivalis were first introduced into gardens in the late 1500's from Europe, where their range spreads from the Pyrennees in the West to the Ukraine in the East.

The "Flower of Hope" grew in popularity around the time of the Crimean War (1853-1856) when many soldiers returned bringing with them a new larger variety of the spring bulb, Galanthus plicatus, the Crimean Snowdrop, which they had seen bravely covering the battlefields through the harsh Crimean winters to inspire hope and augur spring.

Our love affair with these delicate yet incredibly tough spring flowers continued to grow over the years and today Snowdrops are one of the most widely traded bulbs in the world.

Snowdrops' many folklore names symbolise hope, renewal and death

Plant Folklore of Snowdrops

Its long, rich history in Europe and the UK means the humble Snowdrop is well established in folklore, literature and religion. The Snowdrop has strong Ecclesiastical associations which is indicated in some of its alternative names such as Candlemas Bells, Mary's Taper and Eve's Tears.  

The snowdrop is a flower of contradictions. On the one hand, for Catholics Snowdrops symbolise hope and purity. Snowdrop garlands were traditionally used in the Candlemas procession on 2nd February celebrating the Purification of the Virgin Mary, which is one reason why they are so widespread along traditional routes to village churches.

Yet at the same time snowdrops have a darker side to their folklore history. Perhaps owing to the flower's white shroud-like petals, Snowdrops have long been associated with death and bad luck. In ancient Greek mythology Persephone or Kore, Queen of the Underworld and the goddess of vegetation, is said to have carried Snowdrops on her return from Hades in Spring. The snowdrops she carried brought back life to a barren, wintery landscape, but also carried strong negative connotations of the Underworld they came from. 

Snowdrops spread by bulb division but ants assist seed dispersal

Also called Death's Flower, the Snowdrop became associated with death for many Victorians. According to superstition, seeing a lone Snowdrop was perceived as a portent of death and it was also meant to be unlucky to bring the first Snowdrop flower of the season inside a house.

Whatever their origins and mythology, Snowdrops hold a deep and enduring place in our psyche, inspiring hope and signalling that Spring is, at last, not far off. In Tennyson’s words “Many, many welcomes, February’s fair-maid”.

The Snowdrop

Many, many welcomes,
February fair-maid,
Ever as of old time,
Solitary firstling,
Coming in the cold time,
Prophet of the gay time,
Prophet of the May time,
Prophet of the roses,
Many, many welcomes,
February fair-maid!
— Alfred Lord Tennyson (1809-1892)

Autumn's Golden Gown

"So fair and foul a day I have not seen..." grumbles the ill-fated Macduff at the beginning of Shakespeare's Macbeth Play. It felt a little like that in Norfolk this weekend

I enjoyed two dramatically different walks among birch trees within twenty four hours; my first a gloriously golden morning showing off Autumn's golden cloak in all its finery and then, courtesy of Storm Angus, a  brief, soggy wind and rainswept excursion which made Litcham common feel very much like a blasted heath.

A wet spring and mild autumn lacking the autumn storms we've had of late has enabled us to enjoy a glorious long-lived golden autumn foliage season this year. But with harsher, stormier weather approaching it may be time to say one last goodbye to autumn's rich vivid beauty and face the cold embrace of stark, hollow Winter, who, after  lurking in the wings for a while and is now stretching out its dark frosty talons.

Autumn Colours and Changing Clocks

Autumn seems to get later and later each year, perhaps a sign of the times in these days of global warming. The leaves here in Norfolk are only just colouring up, so to capture the mood of autumn here is a shot from my garden instead. It's a wild carrot seed head photographed against a backdrop of autumn flowering pink sedum in my butterfly and bee flower garden in gorgeous soft golden light we had yesterday afternoon before the clock change.

There's No Place Like Home

Its been a "Staycation" holiday week for me, and when you are a little under the weather and even the weather's a little under the weather, then the soft golden light at the end of the day and pretty little signs of autumn in the hedgerows and country lanes always give me a lift.

Here a few shots from an evening stroll along the Nar Valley Way. The local barn owl and muntjac deer made a few appearances too this week, though the owl remains camera shy.
