Bionomics

The adults come to light and sugar. Both male and female adults flew very restlessly towards the light source and then quickly moved away from it again. Then they don't sit on the cloth, but instead look for a dark hiding place further away from the lamp.

Flight periods

The species flies in one generation for a month from the last third of June to the last third of July. In doing so, it occupies the time space that Diarsia rubi almost completely leaves out between its two generation periods.
