Davey, P., 2009: This species appeared on Guernsey in 1990, and was followed by the first mainland record on the Isle of Wight in 1994, and then in Sussex the following year; the larva feeds on garlic mustard (Alliaria petiolata), hedge mustard (Sisymbrium officinale), woad (Isatis tinctoria), wallflower (Erysimum cheiri) and treacle mustard (Erysimum cheiranthoides). The species is double-brooded abroad.

The first Dorset moth was trapped in Swanage by R Cox in July 1997. Subsequently light trap records are: Trigon on 18 July 2002 (C Manley), Shaggs on 12 August 2002 and 20 July 2006 (Butterfly Conservation), Broadwey, on 18 June 2006 (P Harris), Cold Harbour, on 9 July 2006 and on 7 June 2007 (B Withers), Swanage, on 17 June 2007 and on 18 August 2007 (R Cox). ‘Mustard’ plants tend to be common in woodland-edge, hedgerow or waste ground situations, whereas wallflower tends to frequent coastal districts. Given the multiple records from same localities above, it would appear that this stunning moth has become established in Dorset.
