A very rare and local species in Belgium, but not seen for a very long time. More than likely extinct.
Wingspan 16–19 mm.
Pupa slightly shiny, blackish brown, abdominal segments reddish brown.
The larvae usually feed between two flat spun leaves or spun silk along a stem and feed on the more basal portions of the leaves. Often the larvae would eat most parts of the leaves, leaving the veins untouched. As the larvae grew they also fed on dead leaves of Vaccinium myrtillus.
The adults rest amongst its larval food plant by day when it is easily disturbed but flies freely in late evening and at dusk en later come to light.
The adults fly from late May towards July.
The species frequents damp or shady woodland, also moorland.
