Davey, P., 2009: A cosmopolitan, mainly tropical and sub-tropical species, and a regular immigrant to Britain, commonest in the south, rarely recorded inland in Scotland, the larva, although rarely encountered, is a defoliator of wild and cultivated herbaceous plants, and sometimes thrives in greenhouses. In the tropics, the larva is a serious pest of vegetables. In Dorset, the moth has been observed in every month of the year, although numbers vary annually depending on the size and northward extent of migrations from the Mediterranean region and mainland Africa, where it is resident. The build up in numbers as the year advances is similar to other common immigrant species. Unusually high numbers of adults were trapped in 1992, 1996, 2000, 2003 and 2006. There is no evidence that the Pearly Underwing overwinters in the county; it is thought that all stages perish during the first frosts of winter. The status of the moth is therefore of an immigrant and transitory resident.
