1832 Eupithecia assimilata (Currant Pug)

Geometridae, Larentiinae - Wingspan: 18-24mm.

A common species throughout the UK. In Cornwall they seem to be a bit more common in the east of the county than the west, but numbers are not as prolific as some common species. Very similar to the Wormwood Pug, but some features serve to separate them, when they are a little faded. The central fore-wing spot is very prominent and elongated in the Currant Pug. Where the white spots near the rear outer edge, and the leading edge dark spots are faded, this species also has specific body patterns, where the front abdominal segments make a light inverted triangular shape, and the rest of the abdomen has a dorsal white line. Although the Wormwood Pug has a broad white band, it is not triangular, and neither is there's white dorsal line on the abdomen.

The flight season for this species ranges from May to August in two overlaid generations, but occasional specimens may be seen in April or September.
