Host plants:
Broom species (Sarothamnus, Genista)

Habitat:
Chesias legatella inhabits broom edges in and on the margins of acidic forests and similar sites such as sandy heaths with occurrence of brooms.

Life cycle:
The eggs overwinter and the caterpillars live in the spring to June. The moths fly between late September and early November.

Endangerment: endangered

Endangerment factors:
In many places broom heathlands are almost extinct (due to overbuilding, afforestation and especially agricultural intensification like asparagus fields). In addition, light forest edges become rarer and rarer due to too dense afforestation and eutrophication.

Remarks:
Chesias legatella is distributed from north Africa across Europe to Southern Scandinavia.
