An extremely rare and local species in Belgium. Rarely recorded.
Native
The young caterpillar overwinters. They live in webbed cavities in the moss/root collar area at the base of Festuca tussocks.
The moths fly mainly in July and August.
The larva feed on the roots and stem bases of meadow grass.
It inhabits open, shallow, and warm-dry habitats and nutrient-poor grasslands.
