Technical description and variation
For a key to the terms used, see Glossary of entomology terms.

The wingspan is 45–60 mm. It is like Epipsilia latens Hbn. but larger; the forewing paler, the stigmata with distinct pale and dark outlines. pyrophila Schiff. is ochreous grey; suffusa Tutt is darker, the forewing being blackish grey; —latens Stph. is unicolorous black, with still more intense markings.[1]

Biology

Adults are on wing from June to September.

Larva dark brown; the subdorsal area brownish-tannish peach; dorsal line thin, pale, edged with black; a row of dorsal V-shaped marks; an interrupted white lateral stripe.

The larvae feed on Gramineae, Rumex and Taraxacum species.[2]
