Eupithecia denotata (Hübner)

Including E. denotata subsp. jasioneata Crewe.

Campanula Pug.

Adults. Posterior tibiae of males 4-spurred. Wingspan 22–24 mm. Forewings not noticeably elongate; the outer margin convexly curved; the costa more or less straight; apically blunt.

Forewings relatively conspicuously patterned to dingy; in subsp. jasioneata fuscous with a biangulate postmedian fascia, a curved postmedian one, rather conspicuous dark striae, or (subsp. denotata) brown with the patterning far less contrasty, the faciae very faint or lacking; usually with a detectable pale subterminal line that is dentate near the costa. The forewing patterning not restricted to dark discal or costal and discal spots, or more or less confined to the dark discal spot; without a predominant anterior-median triangle of dark spots. Forewings consistently with a dark discal mark. The discal mark dot-like; not whitish-edged; black and distinct. Forewings usually with a pale tornal spot (this elongate). Forewing fringes somewhat chequered to not chequered.

Hindwings light grey, striated more darkly dorsally and postmedianly; patterned similarly to the forewings to less conspicuously patterned than the forewings; conspicuously patterned to rather plain; transversely striated; with a clear discal mark (or this rather faint and grey); without a pale tornal spot; the fringes conspicuously chequered to not conspicuously chequered.

The abdomen conspicuously patterned; neither ringed nor banded nor white-based; with lateral series of black spots (sub-basally).

Genitalia. The male abdominal plate in the form of a single sclerotized patch with retuse apex, or in the form of a single sclerotized patch with entire apex. The bursa copulatrix with ornamentation conspicuously restricted in distribution (mostly distal); conspicuously spiny.

Early stages, ecology. Botanically specialised. Foodplants herbaceous-dicotyledonous; Campanulaceae. The larvae found on Campanula, Phyteuma and (subsp. jasioneata) Jasione montana; feeding on seed capsules 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, Wales, and Ireland (the western component mainly subsp. jasioneata).

Special key characters. Forewings not dominated by double ante- and postmedian lines. Hindwings light brown, or pale grey.
