Angelica sylvestris
Ova are laid on angelica ("Angelica sylvestris") and ground-elder ("Aegopodium podagraria") in June and July, and in the Autumn. Larvae of the first generation feed in May and June in spun leaflets of their host plant, while larvae of the second generation mine a stem immediately below an umbel, causing it to droop and wither. When full grown, larvae leave via a small hole just before the junction above the main stem. Pupation takes place in an open network cocoon amongst detritus on the ground.
