There are only some very old observations of this species around Brussels and Leuven (BR) in 1858. At present, this species is most likely extinct in Belgium.
The forewings are brownish grey contrasting with a broad white costa-line. The antennae are clearly ringed. This species has a wingspan of 11–13 mm. The antennae are distinctly ringed till the tip.
The laterally strongly compressed and bivalved case is pale yellow.

The larvae live from autumn till May. They resume feeding after wintering.
This species flies from the end of May till well in July.
This is an oligophagous species living on a variety of different plants although some are unconfirmed or even doubtful. But most host plants belong to the Rosaceae and Fragaria vesca is one of the primary hosts.
