A very rare species in Belgium, not been seen for some time. Possibly extinct.
Pinkish brown, green between the segments; head capsule, prothoracic plate and last abdominal segment brown; pinacula black inside greyish rings.
Whitish cocoon, pupa brown.
The first instars spin two leaves together and eat small blotches in these leaves. Later instars drop to the soil and construct a silken tube adjacent to the root of the foodplant on which they feed.
Pupation inside the silken tube.
Adults are active during the night and readily come to light.
One generation a year: July–September.
Sandy environments or in limestone areas.
