Male underside
with extensive markings along the veins - closely resembling the spring
brood Green Veined White, P. napi.

Female showing
extremely heavy dusting of grey on upperside and
heavy veining on underside.

Male also has
heavy markings but lacks completely the
ample dusting found on the upperside of the female.
This species appears to replace
the Green Veined White, P. napi, at high altitudes in the Alps
and the Carpathian Mountains. The males are more heavily marked in
comparison but it is the females that are unmistakable. They are covered
in a very heavy dusting of brown scales giving a rather dirty
appearance.
Unlike co-geners with
which it may fly (A. napi,
rapae, mannii,
and ergane) it usually
flies in only a single brood in the summer.
