A very rare and local species in Belgium.
The larva lives in a spun shoot or between spun leaves of the foodplant, sometimes gregariously.
Pupation amongst detritus or in the earth.
The adults are active at night and occasionally come to light.
One generation a year: from July till September.
The main foodplant is Angelica sylvestris though the species has been recorded from quite some other species of Apiaceae.
Wet areas like fens, marshes, and river sides.
