My research (Kolev, in print) shows dardanus to be a
separate species from P. pyrenaicus, which is endemic to the
Pyrenees and the Asturian mountains in N Spain and S France.
Very local in the Balkan Peninsula and the steppes of E Ukraine
and S Russia, widespread in Turkey, Transcaucasia and Caucasus.
in Bulgaria: Alibotush and Pirin, 1700-2212 m
Barren karst terrain on slopes and rounded ridge crests.
One generation from late June to August; emergence is protracted.
Larval host plant Androsace villosa L. (Primulaceae) (Tolman
1997). Both sexes bask avidly on stones and bare ground; they are
strictly confined to their barren habitat and hardly ever leave it.
status: This remarkable species has a very limited
range in Bulgaria. It does not appear in direct danger at present as it inhabits
remote massifs with a minimum of human activity.
