Description

The wingspan is about 43–48 mm. Forewing blackish fuscous; the space between outer and submarginal lines paler, brownish grey, the upper stigmata filled in with white or ochreous; the median area and terminal area on each side of submarginal line blacker; a deep black streak from base below cell and a thick black space along submedian fold between claviform stigma and outer line; hindwing dull ochreous grey with dark veins and cellspot; the terminal half fuscous and the fringe whitish; — lunulina Haw. is blacker with both stigmata dark, the reniform with a few pale dots on outer side; — fribolus Bsd. is uniformly black with all markings obscured; the only pale markings being the whitish dots on outer edge of the reniform and the praeapical costal dots; — ab. variegata Stgr., from Armenia and Turania, has the thorax variegated with white; the forewing with whitish suffusion beyond reniform and at apex; the black markings strong; the hues defined by whitish, and the stigmata with white annuli; this must be very nearly the same as oblonga Haw., which Staudinger has ignored; the grey brown form with the markings fairly plain is abjecta Hbn., of which the extreme form, unicolor Tutt, with the markings obsolete, and the whole wing grey brown, is the usual form in the east of Britain. .[1]

Adults are on wing from June to August. There is one generation per year.

The larvae feed on various grasses, including alkali grass species. They mostly feed on the bases of the stems and roots.[2]

gollark: This is not really, as far as I know, practical for machine-code-y systems, because they don't need to go through a function call or whatever to load new code for execution.
gollark: What I had to do one time to reverse some obfuscated code on potatOS was hook `load` to log newly loaded code to a file, it's called "Protocol Epsilon debug mode" and is still in there.
gollark: I'm assuming you don't mean "polymorphism" in the sense of "functions which can take/return multiple types"?
gollark: no.
