Eupithecia goossensiata Mabille

= E. absinthiata f. goossensiata, when viewed as an ecotype; E. minutata Guenée; E. notata Stephens.

Ling Pug.

Adults. Posterior tibiae of males 4-spurred. Wingspan 21–23 mm. Forewings distinctly elongate (more so than in E. absinthiata); margin convexly curved; more or less straight to arched; apically blunt to somewhat pointed (more pointed than in E. absinthiata).

Forewings dingy; brown to fuscous, with striae more sharply angulated than in E. absinthiata, these blackened on the costa and on the edges of the median band also forming dark costal spots; subterminal line whitish, interrrupted, forming a tornal spot. The forewing patterning more or less dominated by the conspicuous, dark discal and smaller costal spots to not restricted to dark discal or costal and discal spots; dominated by two dark costal spots which form with the discal one the corners of a conspicuous anterior-median triangle; triangle of spots not equilateral. Forewings with a dark discal mark. The discal mark dot-like (less elongated than that of E. absinthiata); not whitish-edged. Forewings with a pale tornal spot. Forewing fringes somewhat chequered to not chequered.

Hindwings similar in colour to the forewings, paler and more ochreous-tinged than in E. absinthiata; less conspicuously patterned than the forewings; conspicuously patterned to rather plain (like or unlike the forewings); transversely striated (with faint, darker striae, also an obscure whitish tornal dot); with a clear discal mark (this dark grey); with a pale tornal spot to without a pale tornal spot; the fringes not conspicuously chequered.

The abdomen conspicuously patterned; with an interrupted black sub-basal band; in the male laterally neither black-streaked nor black-spotted.

Neuration. Vein 10 of the forewings arising out of 11 and anastomosing with 9 to form a simple areole.

Early stages, ecology. Botanically rather specialised. Foodplants woody-dicotyledonous and herbaceous-dicotyledonous; Compositae (Asteraceae) and Ericaceae. The larvae found on Calluna and Erica, but also Achillea; feeding on flowers and seeds.

Months of appearance, distribution. Adults abroad June and July; larvae found August, September, and 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 not reddish-tinged. Hindwings ochreous, or light brown, or brown, or pale fuscous, or pale grey, or grey.

General comments. Common; cf. E. absinthiata.
