Larch Pug Eupithecia lariciata
Wingspan 19-22 mm.
Distributed widely throughout the British Isles; as the name suggests, this is a species generally found in and around plantations of larch (Larix).
It flies during May and June, when it can be attracted to light.
The small stripy caterpillar feeds on the needles of larch, and is well-camouflaged. The species overwinters in the pupal state.
