Phengaris arion (Linnaeus, 1758) Species

Last modified: March 15, 2022, 10:17 a.m.

The species was formerly known from some very restricted localities in the extreme south of Belgium. Recently no records there. But there is hope, because the species is present (2006) again in the National Park of the Virion. (These are probably stragglers from the south, and arrived here with the warm weather.Latest observation here was in 1992) Critically endangered!
