December Moth
Poecilocampa populi

(Linnaeus, 1758) 1631 / 66.001

General comments:
A widespread and common species, but overlooked in many areas perhaps because some people do not run traps late enough in the year. Adults of both sexes come to light traps in large number and adults are rarely recorded by any other method. They fly early in the evening from around 5 or 6 pm and appear to stop after two or three hours since, on several occasions, traps that were not turned on until about 10 pm failed to attract any examples of this species in areas where the moth is present.

Hertfordshire Notes:
Likely to be present in almost all the map tetrads of the county.

Middlesex Notes:
Curiously absent from the River Lea Valley.

Recorded in 31 (76%) of 41 10k Squares.
First Recorded in 1887.
Last Recorded in 2023.
