Early instars are unknown. Almost full-grown caterpillars construct a silken tubular spinning in a leaflet of the foodplant from where they feed on the adjacent leaves in May–June.
The last instar drops to the ground a spins a loose cocoon in the soil or among detritus in June–July.
It is unknown whether the species hibernates in the adult stage or as an egg or early instar caterpillar. The adults are rarely seen, they occasionally come to light.
