For the county, we have a total of 51 records from 37 sites. First recorded in 1871.
Sutton & Beaumont, 1989: Now rare in the County, probably due to the decline of the English elm, especially in the south where the moth was previously most widespread.
Beaumont, 2002: Scattered records from the south of the County indicate that this species persists at low density.
2012 (CHF): The only two areas where this moth has been recorded recently are in the south of VC63 and in the Ripon area. Other elm-rich areas on the magnesian limestone should be targeted as it is quite elusive and only ever appears in small numbers. There were records at Spurn in 1995 and 2010 and it is not obvious where they originate from. Our populations are the most northerly in the country.
