1860 Pasiphila rectangulata (Green Pug)

Geometridae, Larentiinae - Wingspan: 16-22mm.

A common species throughout the UK, and widespread in Cornwall. When freshly emerged, the only other Pug similarly coloured is the V-Pug, but that species distinctive "V" Mark and the rest posture serves well to differentiate them. Faded Green Pugs, tend to lose their green colouration on the wings, although it may stay around the body area. With a superficial similarity with blotches near the tips of the fore-wings, when grey, it can sometimes be confused with a Mottled Pug, although with that species the blotches are reflected on the underside of the wings. That species is a little earlier than the Green Pug, but can still overlap.

The flight season in the UK is defined as June to Early July, although in keeping with many other species, it is extended in Cornwall with individuals recorded from April to August.
