Sutton & Beaumont, 1989: Widely distributed and usually common in all five vice-counties. However in one area of Rotherham numbers are reported to have fallen steadily since the mid 1940s and it is commented that the larvae and foodplants are similar to those of M. impura (Hubner) which has shown no signs of decreasing over the same period (Barringer & Ely, 1979).
2012 (CHF): Common and widespread across all of the county in good numbers. From about 1994 a second brood has grown and now in most years outnumbers the first. The broods overlap with peaks in July and September.
