This butterfly is very similar to several other European species, but the female in particular usually has a yellowish band on the upperside which aids identification. It is commonest in the Iberian peninsula and flies in two broods a year. Whilst I was in in Galicia in Spain, I unexpectedly found a single individual gliding at the edge of a small wood before landing on its foodplant, Toadflax.
