Host plants:
The caterpillar feeds on grasses. I found the caterpillars most often in late winter and early spring (February to early April) in ground-near shoots of Dactylus glomerata.
Habitat:
Oligia strigilis is present in almost all grass-rich areas: gardens, meadows, grasslands, forest edges etc.
Life cycle:
The caterpillar overwinters and can be found by pulling the ground level, overwintering shoots of grasses in the winter/spring. The moths fly in a single generation from mid-May to early August.
Remarks:
Oligia strigilis is extremely variable in colour. The animal is widespread and often common in Europe and temperate Asia to Western China.
