Acronicta euphorbiae (Denis & Schiffermüller, 1775)

Host plants:
The larvae are polyphagous. I found them in the Alps often at Alchemilla sp. and once at Gentiana punctata.

Habitat:
Acronicta euphorbiae inhabits nutrient-poor grasslands, alpine meadows, dry gravel banks along alpine rivers, rocky slopes and similar habitats.

Life cycle:
Acronicta euphorbiae flies in one or two generations from April to August. Only a single generation is observed at higher altitudes in June/July. I found caterpillars in the Alps from July to September.

Endangerment: strongly endangered

Endangerment factors:
North of the Alps, Acronicta euphorbiae is highly threatened due to its higher habitat and space requirements. However, in the Alps, where there are still vast extensive habitats, it is one of the more common species.

Remarks:
Acronicta euphorbiae is locally distributed from Morocco through Europe and temperate Asia to China.
