Adults. Antennae of males simple. Face rough.
Wingspan 27–30 mm. The outer margin of the forewing convexly curved. Forewings not predominantly green, yellow, or black; brown, fuscous or dull olive-green; predominantly green, or greenish, or brown, or fuscous; with a clear discal mark (this black, linear); with a distinct median band (this darker, but the inner margin less clearly distinguished than the outer one). The outer margin of the hindwings smooth. Hindwings conspicuously patterned to plain; whitish, pale fuscous or light grey, striated grey; with a clear discal mark (this dark); transversely lined.
Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 stalked.
Posterior tibiae of males 4-spurred.
Early stages. Larvae feeding on Stellaria.
British representation. 2 species; South-east England, Central-southern England, South-west England, English Midlands, Northern England, Wales, and Ireland. Living adults found June and July. E. biangulata (Short-cloak Carpet, Cloaked Carpet), E. unangulata (Sharp-angled Carpet).
Subfamily. Larentiinae.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
