For the county, we have a total of 10159 records from 717 sites. First recorded in 1883.
Sutton & Beaumont, 1989: Another species which has increased in recent years. Now recorded as far north as Tow Hill in Widdale (VC65), well north of the line from the 'Mersey to the Humber' suggested by Skinner (1984) as its northern boundary. Whether this species is actually breeding in most of Yorkshire is debatable since it is a strong migrant, and the moths recorded on the coast in 1982 may well have been from the Continent or East Anglia. The only larval record we have is from VC63.
Argus 56, 2008: The spectacular expansion of this moth must be worth mentioning this year with quite huge numbers turning up at some sites. The total of 391 in one trap at Haxby on 29.8.2008 (TJC) would have been quite unbelievable a few years ago.
2012 (CHF): The expansion in range has come from the south and west and coincides with this species becoming regularly double-brooded since 2003. A single brood in July and August has given way to an earlier first brood in June/July and a larger second one in August/September and there are scattered records as late as 1st November. It is now a common moth all over the county though there has been a small drop in numbers since 2009.
