Davey, P., 2009: A regular long-range immigrant that varies in numbers from year to year, the larva is polyphagous on herbaceous plants that include woundwort (Stachys spp.), mint (Mentha spp.), hemp agrimony (Eupatorium cannabinum) and currant (Ribes spp.). In Dorset, the moth has been recorded in every month of the year apart from February. In favourable years late spring immigrations spawn large indigenous broods during the late summer and autumn. These resident populations are often augmented by further waves of immigrants from the continent. Larvae have been found feeding on french honeysuckle (Hedysarum coronarium) and spear thistle (Cirsium vulgare). Three main broods are evident from the data, with a period of sixty-five days, on average, between each peak.
There is no indication that the moth can survive the UK winter, however, the following examples trapped in the first three months of the year all coincided with southerly airflows from very low latitude sources: West Bexington, on 6 January 2002 (R Eden), Portland, on 12 February 2004 and on 23 January 2008 (M Cade), Preston, on 17 March 1999 (P Knight), Gillingham, on 21 March 2002 (G Hopkins).
