An uncommon species and not often observed in Belgium.

The larva makes white blotches on the leaves of Anthyllis, Onobrychis and Trifolium species. The larvae of the summer generation feed on the blossom and seed-pods. Larvae of the spring generation pupate in detritus on the ground, those of the summer generation in the flower-heads of Anthyllis and perhaps the other foodplants.

The adults have two generations per year; May-June and again August. They come to light.
