Bionomics
The young caterpillar creates a fine web tube into which it retreats quickly if disturbed. The final instar caterpillar lives in a system of web tubes with a plant cushion. In autumn it creates a very dense cocoon, which is covered on the outside with plant parts and excrement where it pupates and hibernates.
The adults fly during the day till sunset and later come to light.

The adults fly in one generation a year from mid-April towards early July, occasionally later.
