About Gnophos obfuscata (Denis & Schiffermüller), 1775
Gnophos obfuscata, commonly called the Scotch annulet or Scottish annulet, is a moth species belonging to the family Geometridae. This species was first formally described by Michael Denis and Ignaz Schiffermüller in 1775. Its distribution covers northern, central, and southeastern Europe, and it is also found in Scotland, Ireland, and the Iberian Peninsula. The wingspan of adult Gnophos obfuscata measures 41–46 mm (1.6–1.8 in). The forewing features a dark spot and two often indistinct dark transverse lines. These lines mark the edges of a trapezoidal field that is sometimes slightly darker than the rest of the wing. A faint white transverse stripe may also appear along the forewing's outer edge; apart from these markings, the forewing is otherwise evenly colored. The larva of this species is smooth and greyish-brown, with two small warts on the back of its posterior body segment. Adult moths are active and in flight during July and August. The larvae feed on a variety of plants that grow in heath areas, including Calluna vulgaris and species from the Saxifraga genus.
