Eupithecia dodoneata Guenée

E. dodonearia Morris.

Oak-tree Pug.

Adults. Posterior tibiae of males 4-spurred. Wingspan 19–21 mm. Forewings not noticeably elongate; the outer margin convexly curved; the costa more or less straight to arched; apically blunt.

Forewings relatively conspicuously patterned; pale brownish-ochreous, more whitish in the disc, with bent, numerous rather dark fuscuous striae; the veins partially black-marked with small arrows, especially towards the edges of the slightly paler median band. Forewings with a dark discal mark. The discal mark slightly elongate (oval); posteriorly whitish-edged; black and distinct. Forewing fringes conspicuously chequered.

The termen of the hindwings slightly concave (but somewhat less so than in E. abbreviata); apex somewhat pointed to smoothly rounded into the costa; hindwings whitish-grey with dark grey striae; hindwings patterned similarly to the forewings to less conspicuously patterned than the forewings; hindwings conspicuously patterned; hindwings transversely striated (especially dorsally and postmedianly); hindwings with a clear discal mark (this very small, dark grey); fringes conspicuously chequered to not conspicuously chequered.

The abdomen conspicuously patterned, or plain; in the male with a black lateral streak.

Genitalia. The male abdominal plate in the form of a single sclerotized patch with a pair of apical extensions, or in the form of a single sclerotized patch with retuse apex (the prongs very short). The bursa copulatrix with ornamentation conspicuously restricted in distribution (dense, but anterior and distal only); conspicuously spiny (with small spines).

Early stages, ecology. Botanically rather specialised. Foodplants woody-dicotyledonous; Fagaceae and Rosaceae. The larvae found on oak (including Q. ilex) and hawthorn; feeding on flowers and leafy shoots.

Months of appearance, distribution. Adults abroad April, May, and June; larvae found June, July, and August. South-east England, Central-southern England, South-west England, English Midlands, Northern England, Wales, and Ireland (absent from Scotland, locally common elsewhere).

Special key characters. Forewings with small dark arrow-like markings pointing inwards from the postmedian line. Hindwings whitish, or pale ochreous, or pale grey.
