Adults. Head loosely scaled. Head with a frontal tuft. Eyes glabrous; ciliated (crassalis), or not ciliated. Antennae of males ciliate. Labial palps long; at least three times as long as the diameter of the eyes; porrect to ascending.
Wingspan 27–42 mm. The thorax and abdomen coloured like the forewings, or the abdomen lighter and like the hindwings. Forewings various shades of brown, or brown and whitish; patterned transversely, or complexly patterned; the patterning well marked (usually), or obscure; reniform defined, or undefined; orbicular defined, or undefined; claviform undefined. Hindwings fuscous, or grey; plain; without a clear discal mark; without transverse lines; exhibiting vein 5. Vein 5 of the hindwings strong; arising nearer to vein 4 than to vein 6; parallel with vein 4. Thorax not crested. Posterior tibiae with spines; with appressed scales. Abdomen basally crested.
Living adults found June and July, or July to December, or January to April (2 hibernating species).
Larvae, pupae. Larvae conspicuously hairy, or not conspicuously hairy; posteriorly rounded, or posteriorly tapered; feeding on (mainly) Urticaceae, Humulus and (H. crassalis) Ericaceae; pupating on vegetative parts of the foodplant, or on the surface of the ground (? - “in a slight cocoon”).

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.
