Last Sunday (28 April), I was walking in the mountains near Haro a town in the south of the Rioja region of Spain. A mixture of open woodland and scrub. Some nice butterflies about including some Pyrgus that I struggle with once south of Calais.
I am pretty sure images A & B are of the same butterfly. Unfortunately, I didn’t get a good look at the upper wing surface.
Photographs C & D were taken a few hours apart and are different individuals.
Any help with an explanation please.

Hi Wolfson,

I'm confident #2 and #3 are Spialia sertorius, and the dots on the unh lower submargin suggest the same for #1.

Your last is a Pyrgus given the absence of white dots on the upf submargins, and I can't see beyond malvoides.

Thank you David, very helpful.
