Host plants:
The caterpillar lives polyphagous on herbaceous plants, grasses and young woods.
Habitat:
Agrochola helvola inhabits extensive areas from not too xerothermic grasslands over mesophilic edges to fens, stream margins and other little mown habitats.
Life cycle:
The moths fly from late August to early November. The eggs overwinter. The caterpillar lives from April to June. I found it, for example, near Memmingen in one of the last nutrient-poor grassland embankments in the catchment area of the river Iller close to the ground resting on a blade of grass in the evening in late May.
Remarks:
Agrochola helvola is widespread in Europe and is also found in parts of temperate Asia.
