Lobophora halterata

Lobophora halterata, the seraphim, is a moth of the family Geometridae, first described by Johann Siegfried Hufnagel in 1767. It occurs in central and northern Europe, in a few localities in southern Europe, and eastward through Siberia, Amur, Primorye and Sakhalin to Japan. The wingspan is 20 to 25 millimetres and the forewing is 12 to 15 millimetres long. The forewing is whitish with a very slight brown tinge in the central area, crossed by a narrow dark subbasal band followed by a broader one, while the hindwing is white and usually has a narrow greyer border. The markings vary in intensity. The caterpillar is green, darker below, with two yellow lines along the back, a notched head and two points on the last ring, and the pupa is reddish brown. The moths fly from May to June and the larvae feed on aspen and poplar. Trichopteryx carpinata is a similar species that lacks the blackish basal region on the forewing.
