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.

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.

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!
