Sutton & Beaumont, 1989: This species seems to have become more frequent since the 1970s, especially in the south and east of the County. The foodplants, mayweeds and chamomile are common weeds in some crops on sandy soils, especially brassicae, sugar beet and oilseed rape. This last crop has been planted much more extensively since 1970, which could have affected the frequency of the foodplant and hence the moth (PQW pers. comm.).
Argus 47, 2001-2004:
VC65. Hutton Conyers, 11.5.2001 then eight subsequent records to 2003 (CHF). NEW VICE-COUNTY RECORD.
2012 (CHF): Numbers have declined since 2004 though there has been an expansion of the range up to Teesside in the north east. Arable field margins are not popular places to site moth traps and there would be a lot more records if this sort of habitat was targeted. Apparently doing better to the north of us and has been lost from areas of central England. Do not confuse this species with the larger Shark which flies later.
