Angelica sylvestris
Ova, are probably laid on the seeds of ground-elder ("Aegopodium podagraria"), angelica ("Angelica sylvestris"), wild carrot ("Daucus carota") and burnet-saxifrage ("Pimpinella saxifraga"). The larvae feed within the seeds, spinning two or three together during September and October. Feeding is inconspicuous, but larvae can sometimes be seen on the outside of seeds. The species overwinters in the pupal stage within a flimsy cocoon on the ground.
