Appearance
It is native to the European continent. The wingspan is 23–31 mm. The adults fly from June to October in the temperate parts of its range.Naming
It is sometimes placed in the genus ''Orthopygia'' either alone or with a few other species. Being the type species of ''Orthopygia'', as soon as ''O. glaucinalis'' is placed in ''Ocrasa'' "Orthopygia" is abolished. To further complicate matters, ''Ocrasa'' is now mostly treated as a synonym or subgenus of ''Hypsopygia''.Food
The caterpillars feed on decaying plants and dry leaves. They have been found in some fairly unusual locations, such as ''Buteo'' nests, straw and thatching, and discarded paper.References:
