Cloaked Pug.

Adults. Posterior tibiae of males 4-spurred. Wingspan 23–28 mm. Forewings not noticeably elongate; the outer margin convexly curved; the costa arched; apically blunt.

Forewings relatively conspicuously patterned; light ochreous-greyish or purplish, with indistinct curved fuscous striae; an angulated black sub-basal stria; edges of the median band black-marked, more strongly so towards the costa, posteriorly angulated in the middle; second and fifth fasciae reddish-fuscous, the sixth fuscous. Forewings with a dark discal mark (this oval, black). Forewing fringes somewhat chequered.

Hindwings light ochreous-greyish like the forewings; patterned similarly to the forewings; conspicuously patterned (similarly marked to the forewings, but all the markings greyer and somewhat less distinct); transversely striated (matching the forewings); with a clear discal mark to without a clear discal mark; the fringes not conspicuously chequered.

The abdomen conspicuously patterned, or plain; with a brown or ferrugineous sub-basal band; with lateral series of black spots.

Neuration. Vein 10 of the forewings arising independently, anastomosing with 11 and 9 to form a double areole.

Genitalia. The male abdominal plate in the form of a single sclerotized patch with a pair of apical extensions. The bursa copulatrix with ornamentation conspicuously restricted in distribution (distal and longitudinal); coarsely, conspicuously spiny (with large spines).

Early stages, ecology. Botanically specialised. Foodplants Gymnospermous; Pinaceae. The larvae found on Picea and Abies; feeding on unripe seeds in cones.

Months of appearance, distribution. Adults abroad in June; larvae found August to October. South-east England, Central-southern England, South-west England, English Midlands, Northern England, Southern Scotland, Northern Scotland, Wales, and Ireland.

Special key characters. Forewings exhibiting a conspicuous broad median fascia from costa to dorsum, or without a conspicuous broad median fascia from costa to dorsum; without a dark grey band and two reddish-ochreous fasciae. Hindwings pale ochreous, or light brown, or pale grey, or grey.

General comments. Associated with conifers, this species has become widespread in the British Isles after probable introduction in the mid-19th Century.
