Having spent most of yesterday slobbing around watching gold medals being won I had to get out today. The mission was to find male brown hairstreaks nectaring but although I did see a male in flight it disappeared back into the canopy and I didn't see one at rest. Following where it headed I discovered a new complex of hillside blackthorn meadows but these are where you see females laying, not males nectaring:

Image

It was a good spot. Here is a vista down to the valley with Meleager's blue and a hoverfly:

Image

Image

I'd never been here before so it was good to record species like this. I found a male a little lower down:

Image

I mentioned long-tailed blues the other day but the observation got a little lost in a discussion on sexing white-letter hairstreaks. Well, today confirmed that this is a boeticus year. While checking a patch of hemp agrimony for brown hairstreaks I found at least half a dozen long-tailed blues, mostly frequenting the bladder senna that grew among the other plants. Here are two different individuals, both females:

Image

Image

There were plenty of Provençal short-tailed blues (alcetas) around so I decided to visit a nearby site where I have seen short-tailed blues in the past (argiades) to try for the hat-trick of tails. There were no short-tailed blues there but there were more long-tailed blues. Here is one:

Image

So I repeat - it's worth keeping an eye open for this species in the UK this year! I saw more long-tailed blues today than either red admirals or clouded yellows.

Turquoise blues were prominent today - with many rather small, bright individuals. Here is one:

Image

And here a couple of photos of another:

Image

Image

Plenty of Adonis blues:

Image

Image

Large skippers are still very common:

Image

And as I cycled home I spotted this female Eastern Bath white (followed by another at Martigny station):

Lovely images of Adonis Guy. You've captured the colour and detail perfectly.

Thanks Pauline. It actually took me a long time to work out what settings on my compact to use to capture the gleam of Adonis blues - for years I got them wrong. But I've used Canon PowerShots for seven years now and have finally settled on a good formula. When the settings are right they photograph themselves.

I can't sign off tonight without saying that I've been glued to the screen since my last post and felt pride welling up inside me the whole time. What a marvellous day to be British! In my youth I was a rower and a distance runner so it was natural that I should be gripped by those events. But I've never been a ladies' heptathlete and that gave me the biggest lump in my throat of all. And it was set to yet another magnificent alpine storm outside. I got a photo of it just before it got too dark, as heavy clouds and rain swept in.

PS - I've just noticed the clutch of shield bug eggs in the Meleager's blue shot - 14 eggs, one for each gold so far ...

Popped down to the woods at lunchtime to see if the purple emperor egg I found the other day had hatched yet. It hadn't:

Image

I looked in vain for more eggs but was delighted, just as I was about to leave, to see an empress cruise through. She didn't go in the direction I wanted, towards the parts of the woods where I usually find eggs, but in the course of time she'll probably get everywhere and there might be some more little green and brown goody bags next time I look.

I was pleased to see a few white-letter hairstreaks had survived all the recent storms. Here is a male...

Image

... and here a much fresher female, though I couldn't approach her for a close-up without trampling through nectar plants, which I never do:

Image

This is the best detail my camera does at that kind of distance (about 2m):

Image

It's good enough to see she's still in reasonably fine fettle.

More hermits.

Nine days ago I visited the Jura to see my first ever hermits. It was the very beginning of the season, apparently, and only males were flying, so this morning I was up at 05h00 again to look for some females. As I had hoped, there were plenty. The female is noticeably larger than the male and quite different beneath but her behaviour is the same - sitting around or nectaring with the wings firmly clasped together above the back! Here are a few:

Image

Image

Image

And a few males, also from today:

Image

Image

Image

When I photographed this next one I thought it was a female, from its size and paleness in flight. But it has largely the same markings beneath as a male, albeit much paler and less striking than a normal male:

Image

I suspect it is a well marked female rather than a very pale male.

I had particularly hoped to see male-female interactions, as this is when most graylings show upperside views. Hermits are rather special. The first time I saw a male give chase to a female she brushed him off and he accepted this without any resistance. Next, I saw a male who clearly had intent land some way from a female and start moving towards her:

Image

When he got there he walked around to the front and met her face on:

Image

She was OK with this but something flushed them (I was taking all photos from a distance, so as not to flush them myself) and he had to start again:

Image

Image

Having acknowledged him, she then moved off to nectar, while he stood loyally nearby, watching, guarding and obviously feeling pretty proud of his new girlfriend:

Image

Finally, they settled down in a near lovers' clinch (not quite in contact) and sat gazing into each other's eyes for a little over 2 hours and 15 minutes.

Image

I know how long they were like that for because I kept checking back to see if anything more interesting was about to happen and it never was. It reminded me of the occasional Viz strip, 'Planet Bore', in which rather badly drawn things from another planet sit around doing absolutely nothing. When I came back on my 2 hours and 30 minutes check they had gone and were nowhere to be found.

So no upperside shots. To make sure I had something on my website to illustrate the colour scheme I took a video and extracted this frame - a bit lame but it will serve the basic purpose:

Image

I didn't take many photos of other species. Here is the hermit's giant cousin, a great banded grayling:

Image

For once, the Swiss trains didn't run smoothly on the way home, apparently due to 'un accident de personne' on the line in Montreux. This is often a euphemism for a suicide and one of the conductors suggested there had been one. Whatever actually happened, the result was the cancellation of all trains from Vevey onwards for the rest of the day, and thus a late return home for me. As we were stuck outside Vevey, I saw a family of goosanders on the lake and got this shot through the train window:

Great photos Guy- the female Hermit reminds me of a cross between a Meadow Brown ( hind wing) and a Grayling (fore wing). Seems strange seeing summer Goosanders as I'm used to seeing them in large groups during the winter.

You would probably enjoy the summer fieldfares, then, Wurzel! A bird that is almost symbolic of winter in Suffolk but present here throughout the summer.

Yes, male or female the hermit is very distinctive and not a butterfly that poses any identification difficulties. I felt really privileged to spend so much time with them today and learn their habits as well as their appearance. But here's a thing: this is a mega, mega rarity in Switzerland, with no more than a small handful of known sites left in the whole country, and this is peak season for the butterfly, and my site is on a public hiking track but I saw no one at all from when I arrived at 09h30 until when I left, at about 14h00. Not another human being - just me, some sheep, some cows, some horses and lots of butterflies.

Back in my local woods I found the lone purple emperor egg had rather drastically changed colour since I last checked it. I don't know if this means it has died and gone off or is just about to hatch ... I'll soon find out.

Image

This dragonfly is Cordulegaster bidentata - a close relative of the familiar golden-ringed dragonfly. I often find it where mountain streams run through woods.

Image

Image

It was hunting rather aggressively and probably eats butterflies ...

Looking good, just about to hatch. The black area at the top of the ova is the little larva's head. It will soon start to chew away at the ribs at the top to make a lid and then open that lid and crawl out. It should finish the egg as its first meal leaving a clear disc on the leaf where the egg once was.

Having done that first meal, it will take up a position on the same leaf's tip or one close by.

Brilliant - thank you CC.

I had hoped it was that. I found a newly born larva in 2010 and I was struck by the incredible size of the black head compared to the tiny body. I can just imagine this little chap all squashed up inside that egg, his head at the top:

Meet Tiberius (Tiberius Julius Caesar Augustus, to give him his full title), nephew (or niece, or just possibly son or daughter) of his Imperial Majesty Aurelian:

Image

In that picture he seems just about to enjoy his first plant meal. Unfortunately, the act of taking the photo alarmed him and he immediately adopted the brace position:

Image

He is actually in the shade there - I was trying to provide some illumation with the flashlight on my iPhone, hence the sharp shadow. You can see the white patch where the egg was higher up the leaf.

I left him promptly, in the hope he would resume feeding and get a bit of muscle on his weedy body, to match the massive head!

I suspect this is a vulnerable time. Already this morning I had to shoo off a predatory fly with huge, piercing mouthparts and various tits commonly pass through that corner of the woods. He needs to enjoy life while it lasts and I will try to follow him as long as he stays around. Having found just one egg in the woods this year I have a rather slim chance of seeing a larva into hibernation ...

Thank you for the enthusiasm! I will, of course, keep a close eye on Tiberius but it is very early days yet. While the summer is still hot and insects and birds abound in his neck of the woods he has lots of predators ... It's nice to think there are hundreds more of these little creatures enjoying their first meals all over the sallows in that ride!

The previous first instar larva I found (in the same complex) was gone by the time I had returned from ten days in England and I never saw him again.

Tiberius didn't eat any of his birth leaf. When I visited this afternoon he appeared to have vanished, but a trail of other nibbled leaves led me to his new resting leaf, a total crawl of about 50cm. I hope he doesn't move this far every day...

This shot gives an idea of his size. He is at the tip of the large sallow leaf towards the bottom of the picture.

Image

He really is very inconspicuous - much harder to spot than the eggs, which sit proud on the top of the leaves. The position in the curled tip of the leaf also offers him protection if the leaf gets blown around in storms or brushed against. Very clever.

Guy referred to Tiberius as:
Very clever.
The point is that Tiberius and his species have probably been around for several million years. By comparison, you Guy, and your kind, are primitive having been here for a mere 200,000 years or so.
Little wonder that Tiberius is giving you the run around. Might as well accept the inevitable now Guy :)

Too true, Jack. I have never regarded my ability to calculate cerebrally as an indication of superiority to all those wonderful creatures who lean on millions of years of inherited instinct to outwit me!

And James T. Kirk never encountered any life form as weird or as advanced as Apatura iris!!

Every day is an adventure. I hope to bore you comprehensively with more Tales of Tiberius, to borrow Pete's phrase, if I am able to keep up with him.

Nipped down to the valley in the afternoon for another shot at brown hairstreak. A strong, gusting wind stopped anything flying at my main site and I drew a blank at my next site too, even though it was calmer.

Long-tailed blues were still easy. Here is a female, looking quite fresh:

Image

I think the yellow sheen on her abdomen is just a reflection of bladder senna flowers above.

A single male tree grayling was my first of that species for the year. He has come out with crumply hindwings and this affected his flight pattern considerably but he could still fly - and did, with gusto. The extra energy he will need to put in will probably reduce his longevity but he should still have a productive life:

Image

This morning an ex-colleague visited and we took a walk down to Big T's woods. He was still there, on the same leaf as yesterday. You can see fresh nibbling on the left:

Image

He will lose the black head and look more like a purple emperor caterpillar when he undergoes his first skin change.
