2021 Annual Report for: Drepanidae / Drepaninae

For species seen in 2021 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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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 2021 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 2021, 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.

65.004 [B&F: 1649] Dusky Hook-tip Drepana curvatula (Borkhausen, 1790) - Rare migrant

Rare immigrant from mainland Europe, appearing in southern and eastern England. First recorded at Dungeness, Kent, in August 1960. In Hampshire the UK's fifth record was discovered at Totton in August 1991. Recorded on the Isle of Wight for the first time at Freshwater in 2002. Wingspan male 37-40 mm, female 40-49 mm. Can easily be overlooked as a dark Pebble Hook-tip D. falcataria, but in that species the outer discal spot on the forewing is much larger than the other two, and on the hindwing the cross-lines in Pebble Hook-tip are more jagged and the wing is noticeably paler towards the costa (MBGBI Vol 7 part 2). Larva feeds on Silver Birch, Downy Birch, Alder and Oak, no evidence of breeding in the UK.

VC11: Boscombe, one, 21 Aug (GBro)

65.005 [B&F: 1648] Pebble Hook-tip Drepana falcataria (Linnaeus, 1758) - Local

Common in woodland, especially of birch, heathland and gardens throughout Britain. Widespread and common in Hampshire and on the Isle of Wight. Wingspan male 36-40 mm, female 40-43 mm. In Scotland moths are distinctly straw-coloured with outer markings darker (ssp. scotica), elsewhere, occasional individuals can be very pale (f. pallida), but only likely to be confused with Dusky Hook-tip D. curvatula, a rare immigrant from Europe, which is darker and has the three discal spots roughly the same size (in falcataria, the outer discal spot is much larger then the other two). Larva feeds on Downy and Silver Birch, over-wintering as a pupa.
