Widespread resident.

Today, this moth forms a regular part of the catch in almost all moth traps across the county, but it is surprisingly more localised than the Single-dotted Wave with which it can be confused by beginners

Recorded in 35 (85%) of 41 10k Squares.
First Recorded in 1887.
Last Recorded in 2024.
