Confined
to the southern half of Italy and eastern Sicily this is perhaps the
most delicate looking Marbled White. It has relatively very little black
on the upperside and almost none, except fine lines, on the underside.
We found it near the north of its range, south east of Rome. It was very
difficult to find and we only located a single colony. This was a grassy
flowery and very steep limestone hillside. The dozen or so butterflies
we found were sailing up and down this steep slope. It was far too steep
to climb so we had to wait for the butterflies to venture to ground
level where we could hope to photograph them.
