Dewick's Plusia
Macdunnoughia confusa

(Stephens, 1850) 2436 / 73.010

General comments:
Immigrant and perhaps now also resident.

As an immigrant, this moth affects the entire of our area with increasing frequency. It was extremely rare until year 2018, in which year it became an annual visitor in multiple locations. It is widely believed to be resident in Hertfordshire and Middlesex but proof is minimal. A "wild" pupa was found on a West London allotment (and yielded an adult) but most reports continue to refer to adults caught at dates coincident with wider immigrant moth activity making it impossible to separate immigrants from residents if indeed the latter are present.

Recorded in 26 (63%) of 41 10k Squares.
First Recorded in 1995.
Last Recorded in 2023.
