Cucullia tanaceti ([Denis & Schiffermüller], 1775)

Host plants:
The larvae feed on some Asteraceae like Achillea, Artemisia and Tanacetum.

Habitat:
Cucullia tanaceti inhabits dry and warm sites such as sandy grasslands, dry slopes or ruderal areas.

Life cycle:
The pupa hibernates and the moths are on the wing between June and August. The larvae are recorded between July and September or early October. I observed them in late August in east Spain (Sierra de Albarracin) on Artemisia absinthium. A certain part of the mature larvae seem to hide on stems near the ground during the day, but the other stays on the plants.

Endangerment factors:
Cucullia tanaceti has already declined severely due to habitat loss in Central Europe.

Remarks:
Cucullia tanaceti occurs from NW-Africa across southern and parts of Central Europe to Western Asia.
