Hibernates as a pupa in a tough cocoon underground, sometimes for several years. The adults come rarely to light.
The adults fly from mid-May till mid-July in one generation a year.
The larva lives on Scrophularia and Verbascum, sometimes many caterpillars on the same plant eating all plant tissues. They prefer foodplants standing in the shadow.
