2020 Annual Report for: Erebidae / Lymantriinae
For species seen in 2020 that had less than or equal to 100 records, full details are included; for more common species, the earliest, latest and highest count by vice-county are shown. The narrative for each species is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species. The tables in each species account summarise the previous status, and that for the current year.
For the maps, all records prior to 2020 are shown by a blue dot (the larger the dot, the more recent), with the current year's records shown in red. As previous records are superimposed on any report for 2020, new sites have greater emphasis (i.e. will show as 'more red').
In the species accounts, an asterisk next to a location indicates a new 10km square record; earliest ever dates are highlighted in orange, and latest ever in red. Initials in the species accounts refer to the recorders listed here. Please get in touch if you identify any omissions or errors, in particular if you have records that have yet to be submitted. Details of how to submit records can be found here.

72.010 [B&F: 2033] Black Arches Lymantria monacha (Linnaeus, 1758) - Local
Local in woodland, especially of oak throughout southern England and Wales, north to Cheshire; common and widespread in Hampshire and the Isle of Wight. Wingspan male 44-47 mm, female 48-54 mm. Normally unmistakable, but the infrequent f. eremita is entirely sooty grey with cross-lines obscured, and could be mistaken for male Gypsy Moth L. dispar. Larva feeds on Pedunculate and Sessile Oak, causing sufficient damage to be a serious pest in some areas, and over-wintering as an egg.

72.011 [B&F: 2034] Gypsy Moth Lymantria dispar (Linnaeus, 1758) - Naturalised
Formerly frequent in the fens of East Anglia, this moth was presumed extinct in Britain in the early 1900s when breeding sites were cleared and drained. Occasional records, mainly from coastal southern England, since then have been regarded as immigrants. However, in the 21st century it has become temporarily established in a very few areas, these all thought to be accidental introductions by the horticultural trade. In Hampshire there has been a pattern of increased occurrence in the 21st Century, possibly related to radiation out from the introduced colonies in London, and breeding was first evidenced in 2019 when larval webs were discovered in Basingstoke. It is probably resident at low levels in urban areas across the county. Wingspan male 48-53 mm, female 59-65 mm. The male has prominent crescent-shaped black reniform mark and black orbicular spot; the female is superficially similar to female Black Arches - but the latter species is smaller with the female Gypsy Moth having a thickset and blunt abdomen - and cannot fly, rarely travelling far from the cocoon and thus any occurrence in Britain of a female moth is clear evidence of local breeding.
The extinct English race fed on Bog-myrtle (Myrica gale) and Creeping Willow (Salix repens). On mainland Europe occurs in a wide variety of habitats feeding on broadleaved trees and bushes.

72.012 [B&F: 2029] Brown-tail Euproctis chrysorrhoea (Linnaeus, 1758) - Local
Local in scrub, hedgerows, parks and gardens, along the coasts on England from Yorkshire to the Isles of Scilly. In Hampshire and on the Isle of Wight formerly confined to a few coastal localities, notably Hayling Island, this species has recently and suddenly greatly increased its range. Larval nests are now plentiful in winter along the coast, mainly on hawthorn, bramble and blackthorn, and it is extending its range inland. Wingspan male 36-42 mm, female 39-41 mm. Larva feeds on Bramble, Hawthorn, Blackthorn, Dog-rose and Sallow, living gregariously within a silken web, causing sufficient damage to be a serious pest in some areas. The larval hairs are extremely irritating, causing rashes on exposed parts of the skin.
