Bionomics
The exact oviposition place is unknown but oviposition is supposed to take place late in the year: August–September.
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.
Flight periods
One generation a year in July–September.

- Daucus carota, Pastinaca sativa and Torilis japonica

Habitat
Grassland and rough ruderal places where the foodplants grow.
