A very rare and local species in Belgium.
The adults fly in two generations a year; during May and June and again onwards from July till August. They are active at dusk and later come to light.
The larva lives in the flowers and seeds of Chrysanthemum, Tanacetum, Achillea, Matricaria etc... It hibernates and pupates in the larval habitation during the next spring.
