The most that can be said of these
rather awful pictures is that they definitely show eastern dappled
white, Euchloe ausonia,
rather than its close sibling, the western dappled white, Euchloecrameri. They were taken in Greece
(more specifically, on the island of Spetses), where it is universally
does not fly. Until recently, the divide between these two was assumed
to be east/west, with overlap in areas of France and Italy, but Leraut
has somewhat muddied the waters by recognising a new subspecies of
flying in Spain and Portugal (ssp. galloiberica,
Leraut 2016). According to his maps, there is additional overlap
precisely where my photographs of crameri were taken, in
Leraut states that crameri
and ausonia differ in the
shape of the outer margin of the forewing, which is on average slightly
more convex in ausonia.
Looking at illustrations, it appears this feature is not constant. He
also mentions the hindwing spots, which are less numerous and less
clearly delimited on ausonia.
This seems to me to hold better. The spots near the body, in
particular, are clear and countable in crameri but rather obscured in ausonia. By this criterion, all my
pictures of crameri are
indeed of that species.
In truth, ausonia, crameri and simplonia form a complex of sibling
species whose general distribution is the southern half of Europe. Simplonia is restricted to mountain
areas while ausonia and
crameri fly at lower
altitudes. In Corsica and Sardinia, a fourth member of the complex
flies, Euchloe insularis.
The present species flies in a series of overlapping broods from early
spring until high summer, hibernating as a pupa.
