A very local and rare species in Belgium.

Yellowish white, head brown.
The larva lives under the bark of its foodplant, causing tunnels. Sometimes, bright brown frass can be seen in the cracks of the bark, indicating the presence of a larva.
The species hibernates in the larval stage. The larva pupates under the bark of the food plant during late spring.
The adults rest during daytime on the tree trunks. At night they come to light.
