Host plants:
The larvae feed on several Artemisia species (often A. herba-alba), but also Achillea and Tanacetum sp.
Habitat:
Cucullia achilleae inhabits dry and warm steppe areas, rocky slopes, dry pastures or similar places.
Life cycle:
The moths occur in several generations between April and autumn. I recorded a female resting on a twig of the host plant during bad weather in the morning.
During summer drought there is a minimum. Then many pupae are in dormancy (estivation). Main larval times are between mid-May and late June and again between August/September and November.
Remarks:
Cucullia achilleae is a Spain endemic and occurs locally in a generally wide distribution in dry and hot regions from the Northeast (Ebro depression) to Andalusia (e.g. around the Sierra Nevada).
