In Norway first found in dry xerothermic calcareous meadows, but later also found to be common in various other dry habitats, such as dry pine forests, open heathland dominated by exposed bedrock, south-facing screes; also man-made habitats like road-fillings. Found at quite low elevations (1000 m a.s.l. or less) compared to southern Europe.

 

Frequency: Quite common and widespread in central parts of Southern Norway, in areas corresponding to the driest areas in the country.
