A very rare and very local species in Belgium, hitherto only known from a few locations in LI.
Native
The larva has been observed to construct a silken vertical tube in the ground where it brings fragments of grasses to feed upon. It hibernates in the silken tube and feeds until July.
Adults are on the wing mainly in August.
The species occurs in very dry, warm to hot habitats, like dunes and sandy areas in heathland.
