Underside of male abdomen showing extensive white tufting - a key
feature in separating foulquieri from alveus.

Another view of the male's abdomen.

At last I am completely satisfied that I have
photographed foulquieri. The key feature for me is the underside
of the male abdomen. This is thickly covered in white hairs, in contrast
with a relatively fine tuft of white hair at the tip of the abdomen in
the Large Grizzled Skipper, P. alveus. It is a particularly
useful feature when comparing with P. alveus centralhispaniae
which shares parts of its range, increasingly so nearer Spain. Other
features are the relatively thick upperside basal hairs and bold
upperside hindwing markings. Yet another feature is the greenish
underside which distinguishes this species from others such as Carline
Skipper, P. cirsii.
All this said, any comments
on identification of this butterfly would be gratefully received.
