Description

Wing span: 25 - 31mm
 
This species is very similar to the Brown Argus, but the two differ significantly in their life cycles. Their ranges broadly over-lap in S Europe.
 
It is sporadic in the mountains of C and S Europe, but is more widespread in northern Britain, Scandinavia and the Baltic states.
 
It can be found in forest clearings and glades, woodland margins and scrubby grassland, and dry, rocky mountain slopes up to 2000m.
 
There is one generation between June and September, depending on altitude and latitude.
 
Larvae feed on many species of Cranesbill (Geranium spp.).
