White-spotted Pug Geometridae

Eupithecia tripunctaria Herrich-Schaffer, 1852

Description: Wingspan 17-21 mm. Forewings greyish brown, with a distinctive white spot at the lower aspect of the pale sub-marginal line. There are also additional white spots in the central area of the sub-marginal line and near the costa, although these are not always present in all individuals. The hindwings are pale whitish brown, with a small white dot at the anal angle.

Key Identification Features:

Sets:  male upperside

Flight Period: End of May to late August. Skinner gives May to September as the normal flight period in Britain.

Status: All the records are from the eastern counties of Armagh and Down apart from a record from Crom Estate, Fermanagh in 2000.

Ecology: This species is found in woodland, fens and other damp habitats. Adults are not overly attracted to light, which might account for its scarceness at many suitable sites. It is probably more widespread in the west than current records indicate.

World Distribution: Eurasiatic; widespread across northern and central Europe, eastern Asia and Japan.

Bradley & Fletcher number: 1835 Agassiz number: 70.160
