I've found this species
sparingly across its range in southern Europe (Spain, France, Italy,
Greece and central eastern Europe) and extremely commonly in north
Africa. It flies in forest meadows where it is strongly attracted to
thistles - from tall purple varieties to stemless yellow ones depending
on availability. The males
can be territorial and will form territories based on a branch of a tree
at the edge of woodland. Here he will chase butterflies as they pass
along the woodland margin. This branch is normally 2 or 3 meters above
head height where they are just out of reach of the camera.
In Europe it is difficult
to distinguish in flight from related species the Silver Washed, Niobe,
High Brown and Dark Green Fritillaries (Argynnis paphia, niobe,
adippe and aglaja) although it is rather duller and greenish.
Close inspection will reveal a green shading (of varying extent) on the upperside
although in some populations this appears to be much reduced, such as in
Crete. The rich water-melon pink underside forewing patch is the key diagnostic feature.
Some of the females in north Africa are enormous.
