About Trichopteryx polycommata (Denis & Schiffermüller), 1775
This species, Trichopteryx polycommata (Denis & Schiffermüller), 1775, has a wingspan of 33–36 mm. It is a handsome species, easily recognized by its fairly elongated forewing, and the shape and arrangement of its rich red-brown markings on a glossy brownish-white wing. For the hindwing, the disco-cellulars are biangulate, with the 2nd radial emanating from the lower angle. In typical specimens, the distal area of the forewing has a moderately distinct dark band or shade, which is set off by the pale subterminal. In the aberration prospicua [Prout], the white ground colour has almost no dark markings, and only the median band is somewhat darkened, making this band stand out very clearly. The aberration albinea Tgstr is almost entirely white, with only very little fuscous marking on the forewing. The larva is moderately stout, nearly cylindrical, with distinct ridges and wrinkles along its sides and small anal points. It has a rather small, rounded green head. Its body is dark green, with a darker mediodorsal line and slender whitish subdorsal lines. The lateral stripe is narrow, and coloured white or pale yellow. The pupa is of medium thickness. Its wing and leg cases are dull green, while its dorsum and abdomen are yellowish red-brown, with the dorsum bearing a slight greenish tinge on its anterior end.
