For the county, we have a total of 332 records from 122 sites. First recorded in 1883.
Sutton & Beaumont, 1989: There have been a few new sites reported for this very local species but most records are very recent so it is not yet clear whether it is established at any of them.
Argus 52, 2006: Often mistaken for a pyralid and consequently overlooked. Four of these  records are from new sites. Double brooded in Yorkshire in July and September contrary to what literature suggests.
Argus 63, 2011:
VC65. Marne Barracks, 15.7.2011 (CHF, JCW, AJW). NEW VICE-COUNTY RECORD.
2012 (CHF): Widespread across much of the county in damp places. There has been a marked increase in records since 2007 and it is not obvious whether this is a genuine change or an increase in awareness that this insignificant moth is indeed a macro.
