The
taxonomy and nomenclature of the rock grayling group of species
changes all the time! At present, it seems to be agreed that what I
have previous called here alcyone (rock grayling) and genava (lesser woodland grayling) are the same species, hermione.
In
areas of overlap between rock grayling and woodland grayling it is hard
to tell them apart - the only reliable feature (but difficult to judge)
is that all woodland graylings are bigger than all rock graylings. The
Spanish butterflies, above, were photographed in such a region. The
Swiss ones are definitely rock grayling, as only that species flies at
the locations I saw them.
