Habitat:
Pachytrachis striolatus inhabits bushy, dry and warm and often rocky places. I observed this species in a rocky and grassy, open Quercus pubescens woodland southeast of Makarska in Croatia.
Life cycle:
Adults usually occur between July and October.
Endangerment factors:
Locally Pachytrachis striolatus is endangered by abandonment of traditional grazing and subsequent reforestation.
Remarks:
Pachytrachis striolatus occurs from S-Switzerland (S-Ticino) across NE-Italy and Istria at least to Albania.
