Yorkshire Status: Scarce and thinly distributed or restricted resident.
Sutton & Beaumont, 1989: First recorded in Yorkshire in 1901 (YNU, 1970 suppl.), this species became quite widespread in suburban areas but seems to have declined again slightly. Recorded quite frequently from all five vice-counties but rare away from gardens. In Meanwood, Leeds (VC64) larvae were found on Delphiniums only a year after being grown from seed, a rapid colonisation! (GB pers. comm.).
2012 (CHF): Not a common moth in the county with about ten records per year, virtually all from gardens growing delphiniums. Almost all records are of single moths. There are surprisingly few records of larvae on the database. Occasional records in September are suggestive of a partial second generation.
