Host plants:
The larvae feed on near-ground plant parts and root approaches.
Habitat:
Agrotis cinerea inhabits warm, gappy and often rocky grasslands. I met a moth in a south-facing limestone juniper grassland in the Swabian Alb.
Life cycle:
The mature caterpillar overwinters. Adults are found from early May to late June.
Endangerment: strongly endangered
Endangerment factors:
Agrotis cinerea has already declined severely due to eutrophication, agricultural intensification, succession (bush encroachment) and overbuilding of grasslands.
Remarks:
Agrotis cinerea occurs in Morocco and Europe to the Urals, also in parts of Western Asia.
