55.2. Sterrhinae – wave moths
Small moths ( 20–30 mm wingspan) with wings usually pale yellow, tan, or brown, and variously marked with diffuse dark bands and scattered dark scales. A few species have pastel shades. Th ey can be separated from other geometrids by wing venation: on the hindwing, the Sc and R 1 veins are fused with the Rs vein for less than one-quarter the length of the discal cell. Larvae of most species feed on trees or shrubs.
Approximately 2800 species of Sterrhinae are known worldwide. Ninety-six species of Sterrhinae are known in North America; 16 occur in AB. Th e Canadian species were revised by McGuffi n (1967), and the genus Scopula was treated again by Covell (1970). Sihvonen and Kaila (2004) and Sihvonen (2005) presented a global phylogeny of the subfamily.
