Triple-spotted Pug Eupithecia trisignaria
Herrich-Schäffer, 1848Wingspan c.20mm.
This species is named after the group of three diffused dark spots arranged in a triangle; two along the leading edge of the forewing and the larger costal spot below.
Other species with similar patterns usually show a white tornal spot, missing in the present species.
It is a fairly local but widespread species, occurring sparsely over England, Wales and parts of Scotland. The adults fly in June and July.
The larvae feed on the flowers and developing seeds of wild angelica (Angelica sylvestris) and occasionally hogweed (Heracleum sphondylium).
