very rare and local species in Belgium, only known from very old
records in the southern provinces. Recently (2006) observed again in
Namur. Seldom recorded.
larva lives in a loose upper-surface silk spinning of a leaf of Daucus carota, Torilis japonica, Anthriscus sylvestris and Chaerophyllum temulum.
adults fly in one long generation a year; from early August till late
November and after hibernating again from March till May. They are
active at night and occasionally come to light.
