An uncommon species in Belgium.

At first, the larva bores into a twig resulting in a twig gall, and later on, the larva turns down the edge of a leaf. It pupates in a cocoon amongst leaf-litter. The pupa hibernates.
The adults are active at dusk and come to light.
The adults fly from April till late June, occasionally later.
The larva lives on Betula or Alnus glutinosa.
It occurs in open woods, heathland, gardens, parks etc...
