Maple Pug.
Adults. Posterior tibiae of males 4-spurred. Wingspan 16–18 mm. Forewings distinctly elongate; the outer margin convexly curved; the costa arched; apically somewhat pointed.
Forewings pale greyish-ochreous with a bi-angulate postmedian fascia, the middle of the disc and the sixth fascia mixed brownish-ochreous; the first five fasciae formed by pairs of dark fuscous angulated striae; the submarginal band interrupted and represented by dark patches, no pale subterminal line. Forewings with a dark discal mark. The discal mark dot-like (minute); grey, indistinct to black and distinct. Forewings with a pale tornal spot, or with a pale tornal spot to without a tornal spot. Forewing fringes conspicuously chequered to somewhat chequered.
Hindwings pale greyish-ochreous like the forewings, with a curved postmedian fascia, more whitish costally, with indistinct fuscous striae; less conspicuously patterned than the forewings; fairly conspicuously patterned; faintly transversely striated; with a clear discal mark (this minute, grey), or without a clear discal mark; the fringes fairly conspicuously chequered.
The abdomen conspicuously patterned; with a brown or ferrugineous sub-basal band (or rather dark reddish-fuscous); laterally neither black-streaked nor black-spotted.
Genitalia. The male abdominal plate in the form of two separate sclerotized components. The bursa copulatrix ornamented over most of its surface to with ornamentation conspicuously restricted in distribution; without spines.
Early stages, ecology. Botanically specialised. Foodplants woody-dicotyledonous; Aceraceae. The larvae found on Acer campestre; feeding on flowers.
Months of appearance, distribution. Adults abroad July and August; larvae found May (i.e., when mature?). South-east England, Central-southern England, South-west England, English Midlands, and Northern England (scarce).
Special key characters. The subterminal line not whitish throughout. Hindwings pale ochreous, or pale grey.
General comments. The antennae of the male doubly fasciculated.

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.
