Sutton & Beaumont, 1989: Only recorded by Porritt (1883-86) from Huddersfield (VC63) and York (VC61/62/64). No further records occurred until 22.8.1955, when W. Reid captured one in Sheffield (Reid, 1955). It was next found in the County in the early 1970s when a great expansion of the species occurred. It spread from the south-east and is now widespread over south and central areas of Yorkshire. It has been commented (PQW pers. comm.) that the peak abundance after the range increase seems to have passed in some areas. Possibly regulatory factors such as predators or parasites are finding a balance suitable for the new conditions.
2012 (CHF): As the relief map shows well, this is a moth of the lowlands. Numbers have levelled out since 1996 and possibly declined a little since though it is still quite widespread. The biggest numbers tend to come from the Spurn area. It is rare to our north with scattered records up to the south of Northumberland.
