This butterfly is remarkable for its seasonal dimorphism. The spring (levana) and summer (prorsa)
forms are so different in appearance they could quite easily be
taken for different species. I see the summer form much more

travel - which is mainly later in the season. In April 2014 I made a
special effort to go to the Jura and photograph the spring form!
eggs are laid on nettles in long strings, said to resemble the hanging
flowers of nettles. I have yet to find these - despite watching females
dithering around in nettle patches looking as if they were going to do
Maps are common in much of central and Eastern
Europe. I have seen them all over France and in the Pyrenees, as well
as further East, in Hungary, and of course in Switzerland.
