About Euphyia biangulata (Haworth, 1809)
Euphyia biangulata, commonly known as the cloaked carpet, is a moth species belonging to the family Geometridae. It can be found across most of Europe, including West Russia, and in the Middle East. This species has a wingspan ranging from 25 to 30 mm. On its forewings, the dark brown central cross-band contrasts against the paler brown basal area and the distal cream-colored band. Two projections extend from the dark brown central cross-band into the cream band. The dark brown cross-band contains a black, oblong discal spot. Greenish scaling is present on the basal field. Hindwings are a plain whitish, pale fuscous, or very light grey color, with pale grey striations and a distinct dark discal mark. Mature stout caterpillars are typically yellowish brown, though they sometimes appear reddish brown. They have a series of blackish to dark brown spots running along their back, a stripe of dusky freckles along each side, and two slender wavy lines lower on the body that enclose a dusky stripe. The head is yellowish brown, mottled with darker brown. Adult moths are active from late June to August, producing one new generation per year. The larvae feed on plants of the Stellaria genus, including common chickweed (Stellaria media). Larvae can be found from July to September, and the species overwinters in the pupal stage.
