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.

Return of the Emperor Dragonfly

Hurray - a wildlife gardening victory has occured!

Checking out the pond the other day I discovered not one but two female Emperor dragonflies, Anax imperator, ovipositing amongst the floating Water Soldiers in the pond. Known as being a pioneer species that prefers open water habitat, Emperor Dragonflies were the very first species to colonise our wildlife pond, but they’d not been sighted in our garden in a decade.

Last year we removed the massively overgrown Water Lily that was swamping the pond so much it had formed its own island. Obviously his highness approves of the change!

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.

An Early Autumn

After a lacklustre summer, it seemed Autumn was all too eager to get started and arrived right on cue. Even as the calendar clocked over into September, the temperatures fell and clouds and stormy rain appeared. But as always September also brought some bright mild sunny days later on in the month to enjoy.

One of my favourite things about this time of year is watching late Common and Ruddy darter dragonflies doing aerial battle and, once paired up, ovipositing over the pond backlit by that soft, hazy golden autumnal sunshine filled with gossamer spider parachutes. This year was no exception and it seems too that the early spring pond work finally bore fruit as at long last I spotted a Southern Hawker female ovipositing amongst the bulrush roots.

Dragonflies are supremely resilielnt and one of nature’s evolutionary survivors. However uncertain and chaotic things may seem, I find it somehow reassuring to observe dragonflies knowing that they have been on this planet for over 300 million years, predating both dinosaurs and birds, and have survived millenia of change.

The Dragonflies Return

One of my biggest concerns last summer was the reduced diversity in the dragonflies visiting our pond, due I suspected to “ecological succession”. Over time ponds naturally fill in and the water becomes more acidic from leaves and organic material. This changes the nature of the habitat and correspondingly, of its inhabitants.

After eight years of benign neglect, our pond plants and marginals had established and flourished so well that there wasn’t a drop of open water left on the surface of our pond. I’d read that certain dragonfly species, particularly larger species like Hawkers require this in order to breed.

True enough, last year we didnt see a single Hawker dragonfly, nor did we see Ruddy Darters and even our usually reliable Broad-bodied Chasers and Four-spotted Chasers didn’t linger. So over winter we prioritised a big clear out in order to create an area of clear water again, although we couldn’t quite bring ourselves to remove our Water-lily root Island.

The long cold spring seemed to delay dragonfly emergences so I was on tenterhooks and initially very uncertain whether our intervention was having a positive or negative effect in drawing in dragonflies. Thankfully the pond seemed to burst into life in our sunny mid June spell. Both Broad-bodied Chasers and numerous Four-spotted Chasers arrived in style, displaying their usual spectacular aeriel battle for territorial hegemony.

To top it off, just a few days ago I was delighted when I saw both Large-Red damselflies mating again and then this Emperor dragonfly ovipositing. This latter species in particular, not seen since our very first season and known for its preference for young very open ponds, seemed a promising sign. Sadly there are still no Hawkers about, but overall, it seems our local Odonata have given our major spring clean a seal of approval, which will hopefully bear more fruit in two year’s time with further new emergences.

You can read a short history of the dragonfly and damselfly colonisation of our new wildlife pond in this blog post . My last new species, a damselfly, arrived the following summer (July 2019) to make ten Odonata species in total. Not bad going for a garden pond!

Sparkling Wings, Spangly Light

The return of fine weather after a week of rain and low temperatures seemed to mark the season’s transition from late Spring into mid Summer. It also brought a flurry of emergences in and arrivals to my wildlife garden.

The Sparrows and Blackbirds have both fledged and are cheeping and chirring charmingly at their parents next to the feeders. As the nectar- and colour-rich magenta Knapweed starts to emerge en masse so do the meadow butterflies. The Meadow Brown and Large Skipper butterflies have emerged, the latter slightly battered so perhaps he had the misfortune to emerge right before the bad weather. In the old Rose garden Goldfinches are frequently landing on the Knapweed buds and a fresh Small Tortoiseshell has been enjoying the Oxeye daisies. A female Common Blue has finally materialised so hopefully my lonesome early male will find his partner.

The other arrival surprised me a little, I’ve been worrying about my pond both for its survival through the drought but also more broadly, due to the process of succession, the gradual growing in causes acidification from leaf matter and less free space. This affects which species can live in a freshwater pond and last year I saw reduced biodiversity the first time.

But my spirits lifted along with the water level thanks to the arrival of a beautiful Four-spotted Chaser dragonfly. He took up the territory for a day or two, on the second I watched as he mated twice with a passing female then hovered over her on protective sentry duty while she oviposited on leaves. Shortly after he moved on to try his luck elsewhere.

A Week of Two Blues

As the last week in what has been sunniest and driest May in England for over a century drew to a close, our now very parched garden yielded two beautiful blue insects. My first Common Blue butterfly of the season finally materialised, maybe benefitting from Bird’s-Foot Trefoil’s resilience to drought conditions and a male Broad-bodied Chaser dragonfly appeared, grateful perhaps that our pond hasn’t, quite, dried out!

And Then There Were Nine...

Watching Nar Cottage's nature pond transform from a muddy hole in our clay earth into a lush, thriving, diverse insectopolis has been one of the most fascinating and rewarding experiences of our five-year wildlife gardening project. Each year we've seen a new species of dragon or damselfly colonise our pond. This year a further arrival brought the grand total to some nine species, five dragonflies and four damselflies. Here they all are, in order of appearance and colonisation. This is the story of a humble pond's evolution into a local wildlife mecca.

First on the scene was a large male Broad-bodied Chaser dragonfly, Libellula depressa, arriving the very first week of June 2014, our pond's first spring, closely followed by a female.  A beautifully marked dragonfly of early summer with a penchant for shallow sunny ponds, the males are a dusky shade of powder-blue and the females a rich mustard yellow.

Broad-bodied Chasers return in 2018 after missing a year. Highly territorial, this one saw off a passing Southern hawker dragonfly.

Next to move in on the 1st of July was my very first damselfly species, the vivid Azure Damselfly, Coenagrion puella. Blue damselflies can be quite hard to identify but I discovered the Azure's distinguishing feature is that it has two short black stripes on the side of its thorax, whereas the Common Blue Damselfly, Enallagma cyathigerum only has one. They took to our pond enthusiastically and set about ovipositing eggs for future generations!

Azure Damselflies ovipositing in tandem. Adult male Azure Damselflies are vivid turquoise. Most females have wide black bars on their abdomen with a lime green colour, about 10% are blue in colouration.

Immature Azure Damselflies are pale lilac (the females predominantly black as in their adult form) and have brown eyes.

Our third arrival was the dramatic and impressive Emperor Dragonfly, another species I'd never encountered before. Carrying an equally imperial latin name  Anax imperator is one of the UK's biggest dragonflies and undoubtedly the most regal. According to Lewington, the Emperor's "vigour, aggression and agility in flight are unequalled in Britain".

The Emperor has a reputation for being a bit of a pioneer species and is known for colonising younger ponds so it made sense to see it early on in our pond's existence. The larva have a fearsome reputation for their creative hunting methods and can occasionally mature in a single year although they usually take two. The surrounding meadow and in subsequent years also pond foliage rapidly filled in to envelop the pond so I never did see an Emporer again.

August brought another two species, one dragonfly, one damsel and the total to 5 dragonflies in our first season. Next up was the Common Darter, Sympetrum striolatum, first spotted basking on the bare earth next to the pond. A month later I was even more excited to see a mating couple zooming around our pond, hopefully ensuring future generations to come.

My second August arrival proved to be the Common Blue damselfly, Enallagma cyathigerum, which has a flight period from May through to September. Blue damsels can be tricky to distinguish from each other, but the single short stripe on the thorax and all blue tail segments help to separate the Common Blue from similar species, its also a stronger flier.

My next new species didnt show up until nearly a year later in late July 2015 but, a bit like busses, suddenly two came at once. The Blue-tailed damselfly, Ishnura elegans and another life first for me, the Four-spotted Chaser dragonfly, Libellula quadrimaculata both showed up the same day. Blue-tailed damselflies are variable in colour and also change colour as they mature so can vary a lot in apperance, in particular there are so-called rufescens (pinkish) violacea (violet) and infuscans (green) female forms.

With its fast, agile flight and distinctive wing markings, the Four-spotted Chaser dragonfly, Libellula quadrimaculata, was a  exciting addition to my wildlife pond's dragonfly tally. Much like the Broad-bodied chaser dragonfly, the males are highly territorial and persistently patrol their patch and return to the same perches to challenge rivals and the two males often held sparring matches over my pond.

2017 only saw one new arrival, bringing our total to 8 different species. Our pond was now 4 years old and becoming pretty mature as a micro-habitat. The Ruddy Darter dragonfly, Sympetrum sanguineum, was our new addition. In the past this dragonfly was a major source of identification confusion for me due to its similarities with the Common Darter and it was satisfying to finally get a good view of the jet black legs that distinguish it most readily.

Last but by no means least in my line up is my recent 2018 sighting of the Large Red damselflyPyrrhosoma nymphula. It made its debut on the Nar Cottage wildlife pond stage on 28th May. Frequently one of the earliest damselflies to be seen, I'd often spotted it in late May on visits to Stoke Ferry and Hoe Rough . With its distinctive colour it was most definitely a newbie in our garden.

Its wonderful to still be seing new species colonise this micro-habitat we created even after 5 years and though my pond's evolution is perhaps slowing and stabilising now I continue to hope for more sightings. Who knows, someday this line up may yet turn into a top-ten list!

 

 

Two Blues and No Greens

After a second fruitless jaunt hoping to photograph some rather shy Green Hairstreaks, which seem to be having a good season this year, my sunny late May Sunday ended up being an impromptu tale of two Blues in my own back garden instead.

As I was resting on my patio I spotted our first blue Broad-bodied chaser dragonfly posing ostentatiously by the side of our (now very low) wildlife pond, barely a day after our first Four-spotted chaser appeared. Both were trying to hold territory and I was entertained by some impressive aerial battles.

A subsequent gentle lap of our garden yielded a female Holly Blue Butterfly busily ovipositing on the native shrubs in our wildlife hedgerow that borders our garden and now in its 5th year is nice and dense. Our wildlife garden just keeps on giving year after year.

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 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.

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…

Female Broad-bodied Chaser dragonfly, Libella depressa, perched on Campion in our winter meadow. Immature males are a similar colour

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.

Our original Emperor dragonfly, Anax imperator, ovipositing on the base of reeds in 2013

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!

Four-spotted Chaser Dragonfly

In between the summer storms we've been having I made a quick dash over the the Norfolk Broads in my first attempt to see a Swallowtail butterfly. I had no joy on the lepidoptera front, but did get to see my first ever Four-spotted Chaser dragonfly, Libella quadrimaculata, which was busy egg-laying in a pool.

According to the British Dragonfly Society, Four-spotted Chasers prefer shallower bodies of water with good emergent vegetation and areas of clear water and are widespread across the UK. Named after the striking dark spots half way along its wings, there is 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.

Southern Hawker

Its late summer and already the weather is feeling very autumnal. I recently visited one of my favourite secluded dragonfly haunts and found the southern hawkers and common darters still zooming about and dancing over the water.

Hawker dragonflies are a fearless and highly competitive dragonfly species. They spend most of their time in flight hunting out smaller insects as prey. They are also highly competitive. It's beautiful to watch them do acrobatic battles with other dragonflies above the water, quite often there are conflicts between several dragonflies at once, reminiscent of a battle of Britain dogfight.

Like most predators. hawker dragonflies are very curious by nature and quite often one would come right up to hover in front of me for a few seconds before "buzzing" me and zooming off again. This shot was quite a challenge - it was taken handheld using manual focusing on my 180mm macro lens.
