Keep going back at different times of day, Goldie. If they're there, eventually you'll see them necataring. They're easier to find later in the season, too.
Yesterday I went up to a site where a friend says silvery argus,
nicias, is common. It was a perfect day and I saw thousands of blues but no
nicias. I bump into this species occasionally but still have no regular site for it. Here are a few of the other things on the wing:
(mazarine blue surrounded by adoring little blues)
(silver-studded, mazarine and little blues)
(glandon blue)
(cranberry blue)
(geranium argus)
Today, Chris Jackson of UK Butterflies popped over from Evian-les-Bains, where he's currently on holiday, to see some true upland butterflies. I took him to one of the nearest high spots, where I knew there would be good species. The weather was not so good for much of the walk, and there was not a glimmer of sun while we were at the high point of our walk, but he still got more lifers than you can count on two hands. I held back to let him get the photos first, but got a few myself too.
His first lifer was actually on the drive up the hill. I suggested stopping on a corner where I have once seen purple emperor, just on the offchance - and after 5 mins we got back in the car with emperor photos in the bag! Very bad views, and an insect that had seen better days, but a good start nevertheless:
Several
Erebia were lifers for him. Here he is photographing his first
mnestra:
Other
Erebia seen were
tyndarus,
pandrose,
euryale and either
melampus or
epiphron - I identified it casually as
melampus through the net but when I saw his photo on the camera had doubts. I'll be able to clear that up when I see the photo on the screen.
Fritillaries included lots of shepherd's fritillary,
Boloria pales but no mountain fritillary,
B. napaea.
(shepherd's fritillary, female on left, male on right)
Right at the top, while Chris ate his lunch, and despite the fact it was cool and overcast, I said with a swagger I'd go and find him a Cynthia's fritillary. Sure enough, I found this male with slightly curly wings:
I expect it could fly but it didn't even try to under the conditions. I gently moved it from right beside the path, where dogs and walkers could have hit it, and Chris got some
cynthia shots. A second male appeared later, but disappeared as Chris was approaching for photos. I took a long-distance shot from an angle:
Other fritillaries were Grisons fritillary and the mountain subspecies/form of marsh fritillary,
debilis. This is a female:
Another lifer for Chris was peak white:
This is an idas blue ...
... and this an alpine Heath:
Finally, Chris photographing that
debilis:
Other species seen on the walk included swallowtail, Apollo (from the car as we arrived), mountain clouded yellow, orange tip (much lower down), pearl-bordered fritillary, alpine grayling, mazarine blue, little blue, dingy skipper and Essex skipper.

Do you ever see females?
Well done, sir!
