Localities: Yardley Chase, Kirtley Coppice, Rockingham Park and Barnack Hills & Holes.

Currently Pitsford Reservoir is perhaps the best Northamptonshire site with sixteen examples being recorded in 2001 to two 125 m.v. light traps running nightly. By comparison, fifty years ago in 1951 a single 80 watt m.v. light trap running in a Wellingborough garden throughout the season attracted 321 examples of the moth, a typical number for this site in the early 1950’s.
