A widespread species of chalk and limestone across
most of Europe. It is missing from all but northern Spain, UK (except
the southern chalk hills), Scandinavia and north Africa. The males are
of a soft papery blue which distinguishes the Chalk Hill Blues from all
other blues. Unfortunately it is extremely similar to the Provence Chalk
Hill Blue with which it has a range overlap around the Mediterranean. I
am not convinced the species can be told apart very easily as both
species are very variable in many wing characteristics. In Spain there
are several subspecies named. See also the Azure Chalk Hill Blue,
L.
coridon caelestissima plus
L.
c. asturiensis. In Slovakia there is a small area of double
brooded butterflies. These are potentially a separate species which has
been tentatively called L. slovakius. We found a species of
Lysandra that would fit the description at the end of June.
Unfortunately the normal coridon would be beginning to fly at
that time and without any external diagnostic characteristics I
cannot confirm that they were slovakius. They were worn though
which probably meant they had been flying for about 2 or 3 weeks so...
possibly....? |
