A very rare and local species in Belgium.
Bright green with a thin darker green dorsal line; head capsule yellowish green; prothoracic plate green with a few black dots; pinacula pale green.
A loosely spun cocoon in the soil or among detritus; pupa brown.
The caterpillar lives in a loose upper-surface silk spinning of a leaflet; the sides of the leaflet are drawn upwards but most of the time not closing into a tube; full-grown in June–July.
The last instar drops to the ground ans spins a loose cocoon in the soil or among detritus in which it pupates.
The adults are active at night and occasionally come to light.
One long generation a year: from early August till late November and after hibernating again from March till May.
Open grassland and scrub where the food plants grow, ruderal places.
