A very rare and local species, recorded for the first time in Belgium in 2016.
Native
Dark green or greyish green: head capsule and prothoracic segment black.
A loose silken cocoon; pupa brown.
The caterpillars live, often gregariously, in the flower heads or between leaves spun together. Where the species occurs, it can sometimes be very common.
Pupation in a loose silken cocoon in the soil or amongst detritus.
The species hibernate in the adult stage. The adults are rarely seen, they are active at night and occasionally come to light.
One generation a year from August and after hibernation in March–May.
Monophagous on Seseli libanotis, though the species has rarely been observed on Laserpitium latifolium also.
Ruderal places, sandy areas, road sides.
