Eupithecia insigniata (Hübner)

Consignata Borkhausen, consignaria Boisduval.

The Pinion-spotted Pug.

Adults. Thorax brown, with a white central stripe. Posterior tibiae of males 4-spurred. Wingspan 22–24 mm. Forewings distinctly elongate; the outer margin convexly curved; the costa arched.

Forewings at least towards the costa relatively conspicuously patterned; pale grey, greyish-ochreous or greyish-whitish, with a conspicuous dark anterior-basal patch and dark costal marks; the veins partly blackish; two pairs of blackish-edged whitish sinuate striae limiting the median band, the second posteriorly ferrugineous-edged; a ferrugineous-brown costal blotch before the first pair and another beyond the second, and between them three brown median striae ending in a dark fuscous costal suffusion. Forewings with a dark discal mark (this large, touching the dark fuscous costal suffusion). The discal mark shortly elongate; black and distinct. Forewing fringes conspicuously chequered.

Hindwings whitish-grey, with two pale grey posterior striae; patterned similarly to the forewings to less conspicuously patterned than the forewings; conspicuously patterned to rather plain; weakly dorsally and postmedianly transversely striated; with a clear discal mark to without a clear discal mark (this pale grey or indistinct); the fringes conspicuously chequered.

The abdomen dark fuscous, plain; neither ringed nor banded nor white-based; laterally neither black-streaked nor black-spotted.

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; conspicuously spiny.

Early stages, ecology. Botanically specialised. Foodplants woody-dicotyledonous; Rosaceae. The larvae found on apple and hawthorn; feeding on flowers and leafy shoots.
