The caterpillars can reach a length of about 15 mm and are coloured brown to dark brown. These moths are quite variable and can be confused with some other species (Olethreutes obsoletana, Celypha doubledayana, Orthotaenia undulana).Julius von Kennel provides a full description.

The adult moths are active at dusk and fly from late April to September in the temperate part of their range (e.g. Belgium and the Netherlands). The caterpillars can be encountered from April to September. It is a univoltine species. The larvae are polyphagous, feeding on various herbaceous plants (Daucus spec., Succisa spec., Ononis sp., Mentha sp., Caltha sp., Ranunculus sp., Inula sp., Cirsium sp., Chrysanthemum sp., Lysimachia sp., Chenopodium sp.. Urtica sp., Artemisia sp., Filipendula spec., Fragaria sp., Sanguisorba sp., Epilobium sp., Rubus sp., Salix sp., Betula sp., Ligustrum sp.. Larix spec., Picea sp.).
