Some friendly September weather did seem to bring out a small flurry of late emergences in some species who had a tough year like small coppers. Finger’s crossed for a better season next year!
Photo Blog
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. Bookmark my Norfolk nature photo blog to keep up to date with my photographic adventures.
A Late Small Tortoiseshell Summer
At last! Today, a gorgeously golden August bank holiday Monday, I was in Small Tortoiseshell heaven in my back garden with my Olympus 300m lens. With our wildflower meadow newly shorn, I could enjoy wonderful close up views of a late summer brood of Tortoisehell butterflies. They were a beautifully vivid, rich russet-orange colour as they flitted gracefully between the edge of our wildlife pond and our white buddleia, sweeping in to nectar on the pond side water mint. One butterfly cheekily nectared on a water mint flower so close to the water line that it had a narrow escape from becoming dinner with our rather noisy resident frog.
But I’m lucky to be enjoying this sight, because, despite this week's flurry of emergences, today the Butterfly Conservation Society issued a press release about their worrying decline. The Small Tortoisheshell’s population has plummeted by 73% since the 1970s.
Like many butterflies, habitat loss is an issue, but in addition the growing numbers of a parasitic fly, Sturmia bella may also be a contributory factor.
Due to their complex lifecycle, butterflies need caterpillar food plants for their larval stage, as well as nectar from flowers and fruit after they metamorphose into butterflies. Small Tortoiseshells, like several of the nymphalidae butterfly family, use nettles as their caterpillar host plant.
Gardens are increasingly playing a vital role as a habitat in our rapidly changing environment, so if you are a gardener, allowing a generous patch of nettles somewhere sunny at the edge of your garden really could help a struggling butterfly to recover, and when emerging Small Tortoiseshells grace your flower borders, make late summer days in your garden even more beautifully golden.
Silver Sea Lavender Skies
Sometimes muted grey skies can be a blessing in disguise, as was the case with this shot. High contrast full summer light can be tricky to contend with during the day. This soft pastel palette of sea lavender in Holkham bay was only possible thanks to some heavy leaden grey cloud skies creating soft even light conditions. Taken with the new Olympus 300mm pro-lens.
Of Red Admirals and Queen Anne's Lace
A slightly bizarre blog post title, I know. The connection is that these were the first two subjects that I photographed with the newly launched Olympus 300mm f4.0 pro lens. In old money that gives an effective reach equivalent to some 600mm, a wildlife photographers dream lens. But I wondered if a bokeh was possible, whether the images would really be as sharp as Olympus claimed, and whether the lens might be suitable for long lens macro photography.
Some pretty wild carrot flower seedheads, known as Queen Anne's lace, were my first attempted subject. Immediately I took the lens cap off I had a nasty shock. The lens simply wouldn't focus. The focus point refused to stay still, it bouncedaround lly all over the place. Feeling deflated and not a little seasick from the circular motion I went to do a little investigation and realised that I needed to upgrade my camera's firmware to support the latest in camera focus stabilisation.
That done. the camera's focus improved dramatically and behaved beautifully again. I finished taking my shot of the wild carrots' dainty seedheads and was pleasantly suprised at the sharpness and bokeh I that was able to achieve.
That still left the question of whether, with the predictably long minimum focus distance of 1.4m, the 300mm lens would be at all suitable for larger less tolerant butterflies and dragonflies, some of my all time favourite macro subjects to photograph.
An obliging red admiral butterfly very much preoccupied with nectaring on my garden privet hedge allowed me to put the lens through its paces. Because of the long reach, it was a little challenging to get the focus spot on and the 1.4m minimum focus distance was, as expected a real constraint, so I am still dreaming of a nice 100mm f4.0 macro with a minimum focal range more like 40cm. Even so I did get some lovely shots rich with detail and could see this lens working nicely with tree top species.
A Spotty New Dragonfly
The Nar Cottage wildlife garden is starting to become quite mature now, so we were really excited today to spot a new species to the Garden! Our first ever Four-spotted Chaser dragonfly (Libellula Quadrimaculata) was perched up by our our wildlife pond, looking glamourous as he posed. We were even more delighted when he suddenly started zooming round and hooked up with a mate who then started ovipositing, so hopefully in a few years time we may see some more!
Although common in the UK, this was only my second ever encounter with the species, which I first met at Sturmpshaw Fen in June 2012. According to the British Dragonfly Society, Four-spotted Chasers prefer shallower bodies of water with good emergent vegetation and areas of clear water. Named after the striking dark spots half way along its wings, there is also a rare form called prenubia that has an additional dark mark on the end of the wings. Both males and females have a similar appearance and their dark appearance makes them well-suited to Britains cooler climate. On the continent the species is cyclically migratory and occasionally vast swarms can be seen. While this is very rare in the UK, the species is a wanderer, which has no doubt aided its distribution.
Noble Emerald and Gold
Butterflies are having a bad year so far and are thin on the ground, so I have been entertaining myself with other little beasties.
This beautiful, iridescent emerald-coloured beetle is a member of the flower beetle family with a rather grand, royal sounding latin name Oedemera nobilis. It has several fun but less flattering English names too such as thick-legged flower beetle or swollen-thighed flower beetle, although only the females have the fat thighs.
Despite their imposing looking mandibles, adult emerald flower beetles are herbivorous and feed on flower pollen and nectar. This female thick-legged flower beetle is pictured on a Common Rock Rose (Helianthemum Nummularian) up at Ringstead Downs in North Norfolk.
Blowin' in the Wind ....
A Red Poppy for the Somme
In a momentous week that has witnessed a constitutional crisis in the UK and political skulduggery to rival Machiavelli, perhaps the most important event of all was remembering that, only a hundred years ago, Britain was in a state of war with another European country. Our grandfathers were about to face the onslaught of the Battle of the Somme, the most fatal of all battles in the “War to End All Wars”.
A simple common red poppy (papaver rhoeas) blowing in the wind serves to remind us that many, many men gave their lives for our freedom. The peace , prosperity and personal liberties that our European generation has enjoyed until now was won only through the greatest of sacrifices that most of us in our modern lives can’t even imagine – the blood spilled by our forbears.
Our week’s events, when viewed from this bigger perspective, suddenly seem to be all about petty self interest and almost inconsequential. But we can’t afford to take the life we lead today for granted, things could easily be far worse. Intolerance is a slippery, treacherous slope and can at first seem quite innocuous.
Above all we should not forget what the European project was all about when it first started.
Just one little word....
“Peace”
The Uncommonly Beautiful Common Spotted Orchid
Recently I visited Foxley Wood NWT while volunteering with Norfolk Butterfly Conservation Society on a Hawk moth event. As I arrived I spotted this beautiful Common Spotted Orchid (Dactylorhiza Fuchsii) nestled in a corner of the grassy verge.
I simply couldn't bring myself to leave without stopping to admire and photograph the group of delicately coloured Common Spotted Orchids. They must like damp weather as they have done very well here this year!
The name "Common Spotted Orchid" really doesn't do this humble, yet beautiful plant justice. There's nothing common about this diminutive Orchid at all; in fact this flower is the epitomy of subtley, daintiness, elegance and refinement.
Raising a Yellow Flag
The Yellow Iris, or Yellow Flag, Iris Pseudocorus, is one of surprisingly few native British pond Irises. The vibrant and beautiful Yellow Flag makes its home in the damp clay and loamy soils of wetlands and marshes. It thrives in the Fenland habitat of the Norfolk Broads and is widespread across the county.
Yellow Flag is rich in wildlife value, is popular with bees and hoverflies which pollinate its hermaphrodite flowers, The drooping yellow tepals provide a landing platform for insects. The dark yellow patch in the centre, surrounded by a zigzag line acts as a guide directing the insect towards the nectar source. It also acts as a caterpillar host plant for seven moth species including the Belted Beauty Red Sword-grass and Water Ermine. The remaining four moth caterpillars live inside its thick reed-like stems.
Frequently known as "Daggers" it has several other traditional names including Segg, Swordgrass also referencing its blade-like foliageas well as False Acorus, Fleur-de-lis, Water Flag.
It has a long folklore tradition, being said to be the original inspiration for the fleur-de-lis used in heraldic designs. In Ireland it was believed to avert evil and bunches were hung up outside doors during the feast of Corpus Christi. The rhizomous roots yield a black dye and ink and are extremely acrid. Traditionally the dried roots were also used medicinally as a cathartic, emetic and as an astrigent to halt bleeding, while the roast seeds were used to make a form of coffee, though there is uncertainty as to its toxicity. The plant also generated a pleasant essential oil, which was often used to dilute that of the Sweet Flag, Acorus calamus, giving rise to Yellow Flag’s alternative name of False Acorus
Sadly this species tends to gets overlooked by mainstream garden centres in favour of more popular blue-coloured Irises, which are actually Asian in origin, not native to the UK so do not afford the same value to wildlife.
With a little care Yellow Flag Iris can be a wonderful addition to most wildlife garden ponds. In particularly favourable conditions the Yellow Flag Iris will thrive and can become a little over vigorous, so growing it in containers is a good idea to avoid it taking off too dramatically, if you have a smaller ponds or bog gardens.
Fortunately my pond margin has plenty of room and mixed companion planting is providing competition from other marginal plants such as Purple Loosestrife, Meadowsweet, Water mint, Reedmace (Typha), true Bulrush (Scirpus Lacustris) to name but a few. So far this approach seems to have kept the pond margin mix nicely balanced.
Alternative names: Daggers, False Acorus, Flagon, Fleur-de-lis, Jacob’s Sword, Segg, Swordgrass, Water Flag, Water Skegs, Yellow iris, Yellow Flag
Moth Caterpillar host for: Belted beauty, Crescent, Crinan Ear, Red Sword-grass, Rush Wainscot, Water Emine, Webb’s Wainscot
Broad-bodied is beautiful...
Meanwhile our faithful Broad-bodied Chaser dragonflies, Libellula depressa, have returned for another season. This yellow coloured female has been busy making herself at home amongst our new, wildlife-friendly winter meadow Campion flowers in the sunny, sheltered west-facing Old Rose Garden…

Broad-bodied Chasers were the very first dragonfly to show up, arriving in the first week of June 2014, our ponds first season. According to the British Dragonfly Society and Brook’s fieldguide they are an early species that prefer shallow sunny ponds and lake margins. Broad-bodied Chasers are common and widespread across Britain, although they have become less common in Fenland districts owing to the loss of farm ponds. The species becomes less abundant in ponds in late successional stages, but can be encouraged back by clearing marking vegetation.
The wide dusky blue abdomen of the male is unmistakeable. Both immature males and females are yellow and black and look a little like Four-spotted chales but lack the additional dark spots.
In the immature stage Broad-bodied Chasers may wander widely and can be found among hedgerows. Once adults sucessfully mate at a site the male will adopt and guard the pond as his territory, only moving on if he runs out of luck. They certainly proved very obliging to photograph to as they perch frequently in between laps of the pond, returning to the same stem each time to look out for rivals and females. When in residence they’re highly territorial on their short patrols, I even observed one successfully see off a larger passing Southern Hawker dragonfly.

Here there be Emperor Dragonflies
Its been a big week for Nar Cottage's wildlife garden as we discovered that our first "home grown" dragonfly had completed its three year lifecycle. This photo is of an Emperor dragonfly, Anax imperator, nymph "exuvia". That’s the exoskeletal shell left behind after the dragonfly nymph transforms into an adult dragonfly and emerges as a winged adult. The Emperor's emergence takes place overnight so sadly we didn't see it happening.
Emperor dragonfly Exuvia
According to the British Dragonfly Society Emperor dragonflies are highly territorial and rarely settle, even feeding on the wing, while Brook’s fieldguide states that “Its vigour, agression and agility in flight are unequalled in Britain”. Emperors look very like other Hawker species, particularly the Southern Hawker, but often fly with a drooping rear abdomen and their apple-green thorax, which lacks the black stripes of other species, help to distinguish it. The female has a green abdomen, which may turn blue in hot weather.
Emperors are known for being early pioneers of new ponds and were one of the very first visitors to our brand new, bare-earthed pond back in 2013. Three years on and our pond looks very different, now teeming with aquatic life and surrounded by lush native plants and wildflowers that have spread out to cover much of its surface.

In line with their reputation for preferring clear water, to date the Emperor dragonflies haven’t returned since that very first season, but we continued to see lots of Broad-bodied Chasers, Southern Hawkers as well as various damselflies about. Emperor dragonflies will even predate upon other Chaser dragonflies, so I hope our population of those survives its emergence!
Signs of Spring - Insect and Amphibian Emergence
At last...! Some milder days in between the blustery weather, ones when you can really feel the sun on your back. Slowly more signs of spring are present. Insects start to emerge from their overwintering. Though I've yet to photograph my first butterfly of the season (a brimstone on 25th March) I've enjoyed watching out for the early emerging bugs, bees and, that renowned augury of springtime, the first amphibian frogspawn.
My first sign of early spring insect life was this female Minotaur beetle. One of 8 British "Dor" beetles, she emerges in March and roams woodland and pastureland. Despite their size and fearsome looks, Minotaur beetles are herbivores feeding on ruminant dung. After mating she will dig a burrow up to a metre long to lay her eggs.
My second insect sighting was while out gardening. I saw the most gigantic queen buff-tailed bumblebee crash land and nectar furiously on my white crocus. She clambered across our daisy-filled "Meadow Mat" at a surprising rate of knots, looking like she was on a mission, perhaps seeking a nest site to establish her colony for the season. Sometimes known as the Large earth bumblebee from their latin name Bombus terrestris, Buff-tailed bumblebees are one of the earliest bees to emerge in spring and also among the largest to visit gardens in Europe.
Looking closely you can see some mites hitching a ride on her thorax. Unlike some mites, they are not parasitic but are in fact harmless detrivores, who survive by living in the bumblebee nest and providing a cleaning service to the colony, feeding on old beeswax and other detritus.
And last but not least, frogspawn arrived to our pond on the 26th March this year, 4 days later than last year and in smaller quantities. With a greater amount of protective pond plants established, hopefully the tadpoles will stand a better chance this year against our hungry newt population.
In The Bleak Midwinter....
Its January, normally the time of Jack Frost and blankets of white, mittens and snowballs...well not tis year!
El Nino seems to have put paid to all that white stuff in East Anglia for 2016 , which could be one of the warmest (not to mention wettest and windiest!) on record in the UK.
The mild weather also has our plantlife well and truly fooled, with primroses and daffodils nodding alongside snowdrops and aconites. So, instead of a classic snowy winter's scene, this January's blog is of a winter's walk amongst the silver birch catkins at Narborough.

A Silver-Studded Summer
It seems that summer has been slow to start, but nature can't afford to wait and one of Norfolk's rarest butterflies has taken to the wing pretty much on cue. Silver-studded blue butterflies have one of the most amazing symbiotic lifecycles you could Imagine. Frequenting heathland, they plant their eggs on fresh low lying gorse or heather and depend upon two specific species of black ant, Lasius niger and Lasius alienus to complete their lifecycles.
Silver-studded blue butterflies live in small colonies. They are a sedentary species, tending to stay local and fly low to the ground. Unlike the blue males, female studded-blue butterflies are brown in colour, but both share the same silvery blue scales in the black spots on the underside of their hind wing for which the butterfly gets its name.
Adults survive only a few days each summer, just long enough to mate and lay eggs. The caterpillars hatch in spring and are and nurtured by the black ants in exchange for a sugary secretion produced by a special gland. The caterpillar pupates underground in the ants nest before emerging as an adult.
Spring Orchids
Green-winged Orchid
Early Purple Orchid
The arrival of May means we are entering late springtime, augering the arrival of warm days and our early orchids. Here are two you can see readily in Norfolk, the Early Purple Orchid (orchis mascula) that can be seen in ancient woodland where it is often a companion plant to bluebells, and the very small Green-Winged Orchid (Anacamptis morio), a later flowering orchid happiest in open unimproved grassland.
After the whites greens and yellows of early spring now pinker palette emerges among our countryside wildflowers. Amongst others, both the pretty red campion (silene dioica) and herb robert (geranium robertianum), one of several elegant native geranium species, come into bloom during in the month and if you're lucky, you might even see an early poppy.
Lush Springtime
For me, springtime is as much about the pure whites and lush greens, the fresh background colour palette against which the more vivid yellows, pinks and lilacs that pretty spring wildflowers display their wares to early pollinating insects. At this time of year the woodland floor becomes a pastel mosaic of early spring wildflowers such as greater stitchwort, water avens as well as bluebells and campions all in a mad dash to flower and seed before the renewed tree canopy shades their light for the summer season until autumn leaf-fall arrives.
First Frogspawn
This humble image was taken today after a week of cold days and grey leaden skies. For me first frogspawn truly symbolises the onset of spring. What was particularly joyous this year was to find it in my own garden despite my wildlife pond being first filled little over a year ago! While the frogs had left the scene there were plenty of newts hanging around to enjoy a spring feast.
Signs of Spring
At last...the first days when you can feel the warmth of the sun on your back... aconites and snowdrops in full bloom... realising sunset is well past 5 o'clock...it must mean spring is on its way. These photos of pretty snowdrops and winter aconites were taken on a recent snowdrop walk on Lexham Estate in aid of their ancient church.
Happy Valentines Day
The days are getting longer and it won't be too long before we start to see frenetic activity as spring begins to show signs of its impending arrival and our native wildlife start to feel romance in the air. Here are two emerald damselflies in a heart shaped embrace reminding us that love is in the air...
