A very rare and irregular immigrant. Can establish itself for a while after an influx of immigrants. Not often observed.

The caterpillars are frequently eating other caterpillars. Hibernates as a pupa in a flimsy cocoon on or below the ground.
It is active during the day in sunshine visiting flowers. They come to light.
The adults have been recorded from mid-May till mid-August, but most specimens were seen during June and July.
The larva lives on the unripe seedheads and flowers of a variety of plants like Silene, Sanguisorba, Ononis, Artemisia, Centaurea, Hieracium, etc...
