Sutton & Beaumont, 1989: This uncommon and very local species is still present at its only formerly known site at Thorne Moors (YNU, 1970). It has now also been recorded from several other localities in the south of the County.
2012 (CHF): Most records are still from the south and east of the county but there has been an expansion of range and numbers since 2003. There was a marked contraction in 2007 and 8 (eight records in each year), probably due to wet weather in June and July in both years, but this was followed by a further expansion in the next three years with 2010 bringing the first record for VC62. This pattern of expansion and contraction is typical of many species moving further north. Take care not to confuse this species with Green Oak Tortrix Tortrix viridana. Our records are the most northerly in the country.
