A declining species in Belgium, found in several places in the 19th century but after 2004 restricted to some rare observations in NA.
Dark brown, almost blackish; head, prothoracic plate and pinacula black.
The young larva spins a shoot together and feeds within it; later on it lives in a leaf roll.
Pupation amongst detritus or in the earth close to the food plant.
The adults rarely come to light, but they can be found after dark on flower heads, where they feed on the nectar.
One generation a year: July till September.
Open grassy areas, roadside verges and alike.
