A locally common species in Belgium. More observations on calcareous soils where the foodplant is common.

The larvae live gregarious in a web. They feed on the leaves of Euonymus europaeus. Pupation in an almost opaque, white cocoon arranged together in the web, often near the bottom.

The adults fly in July and August. They come to light.

ID: identification of imago of following species as cagnagella, malinellus and padella  are difficult and are only with 100 % certainty done by reference to the genitalia. However an aid to identify this species when fresh, is the white forewing with a pure white terminal cilia. In many cases the best guide to separate these species is often the foodplant!
