Thanks David and Pete.
I think you might be right, Pete. He's full grown and not far off - definitely paling - but I think he's going to sit around digesting that last leaf then zoom off somewhere! I'd hoped he has chosen his place and was just waiting to nip over the top.
I didn't check on Oz today, though he was in place last night. I went off for Provençal fritillaries and it was raining by the time I got back. In fact, it was overcast all day, but it was warm and an amazing amount flew. These were the conditions:
As always, that made photography difficult with my camera, but I was pleased with some of the results.
Here are a male and a female Provençal fritillary, subspecies
berisalii:

(male)

(female)
This is a different male, but still showing the characteristic dumbell:
In this male the dumbell had coalesced into a square:
Also flying were heath fritillary ...
... and knapweed fritillary:
By far the commonest butterflies were Apollos and black-veined whites:
Here, a male Apollo is trying his luck with a female:
She, however, is wearing a shiny new sphragis and so his overtures are doomed ...
Marbled skippers were new for the year ...
... as were small and large skippers:
Pearl-bordered fritillaries still look fresh at this altitude:
Next, I dropped closer to the valley to look for Swiss Zephyr blues,
Plebejus trappi. Despite the weather, I saw two males. Here is one of them:
Altogether I saw three Camberwell beauties. Two were alive, though to be fair, only just:
The white border is almost completely eroded.
The third consisted of four wings on the ground, clearly left by a bird who had eaten the body:
Not so terribly sad when you consider this butterfly must have died today (the wings were still near each other) and would have been about 11 months old.
A scarce swallowtail wing lay in close proximity:
I suspect it was one of the many white wagtails that run along that track.
Southern white admirals were conspicuous. One landed on the ground not far from Minnie:
Marbled fritillaries were behaving similarly:
I could go on and on ...
