The lunar underwing (Omphaloscelis lunosa) is a moth of the family Noctuidae. The species was first described by Adrian Hardy Haworth in 1809. It has a scattered distribution in western Europe including Spain, Scandinavia and Algeria.
This is a variable species, the forewings ranging from pale buff to dark brown although the paler forms are generally more common. The forewings are usually marked with two dark stigmata and a black streak near the apex. The hindwings are whitish marked with a dark moon-shaped crescent on the hindwing is partially diagnostic and which gives the moth its English name.

[edit]The wingspan is 32–38 mm. Forewing varying from pale greyish ochreous to rufous and dark purple brown, the veins generally pale; upper stigmata distinct and filled up with dark, with distinct pale outlines; inner and outer lines double with paler centres, the inner obliquely curved out, the outer simply sinuous; submarginal line pale, preceded by a row of dark spots, and on costa by a black blotch or bar; hindwing whitish, suffused with grey, especially in the female, with large grey cell spot and interrupted submarginal band. The type form is dull red without pale veins; the red forms with pale veins are ab. rufa Tutt;the palest form of all is obsoleta Tutt without pale nervures; a somewhat darker, more brownish form, with the veins pale is humilis H. & Wwd.; brunnea Tutt has the ground colour deep red-brown with pale veins; in subjecta Dup. it is dark grey brown, the extreme development of which, agrotoides Guen., is blackish grey; — olivacea Vasq., from Spain, has the forewing pale olive ochreous, and rubra Vasq., also from Spain, has it pale reddish ochreous. .[1] The larva is light brownish with dark warts, each with a short brush.
