Status

New arrival to the eastern U.S. First report for U.S. collected in Potomac, Maryland in October 2015 (T. Mustelin). Later review turned up earlier U.S. records from Reston, Virginia, going back to October 2013 (BugGuide), indicating an earlier introduction to the United States. Native range is scattered across western Europe. Thanks to Tomas Mustelin, Hugh McGuinness, Tim Reichard, Bob Biagi, and Steve Nanz for their review of East Coast records.

Illustration from John Curtis's British Entomology Volume 5

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.

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.

Biology
