Sub-angled Wave

Scopula nigropunctata, the sub-angled wave, is a moth of the family Geometridae. It is found through most of the Palearctic realm.

The species has a wingspan of 29–34 mm. It is closely related to Scopula umbelaria but smaller, less whitish, the ground-colour being appreciably more testaceous and on an average more strongly dusted. The forewing looks slightly shorter and broader, its distal margin being more strongly curved or bent in the middle so that its anterior part becomes less oblique; the black discal spot nearly always distinct, often large; the median shade, which in the typical form is strong and dark, and the postmedian line are both angled near the costa of the forewing, and the former runs rather more obliquely than in umbelaria; the hindwing has the angle in the middle rather stronger on the average, though very variable; both wings have usually a dark terminal line, interrupted at the
