Pauper Pug Eupithecia egenaria
Wingspan 21-24 mm.
Also known as Fletcher's Pug, this species is a rare and local moth, occurring in a few localities throughout England and Wales. In some parts of eastern and south-east England, the population appears to be recovering or possibly reinforced by continental migrants.
The larvae feed on large-leaved lime (Tilia platyphyllos) and small-leaved lime (T. cordata).
May to June is the typical flight period for this species.
