Historic records are scattered across our area but are surprisingly few. This moth is not, and perhaps never has been, expected annually with us. The years 1947, 1967, 1969, 1992 may have been especially productive. More recent "good" years include 2000, 2002, 2003, 2013, 2016 and 2021.

Recorded in 23 (56%) of 41 10k Squares.
First Recorded in 1930.
Last Recorded in 2023.
