2020 Annual Report for: Ypsolophidae / Ypsolophinae
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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
17.001 [B&F: 0451] Ypsolopha mucronella (Scopoli, 1763) - Local
Local in woodland on chalky soils throughout southern England. Fairly widely distributed across Hampshire, wherever the foodplant is found, but decidedly uncommon on the Isle of Wight. Wingspan 26-33 mm. The distinctive attenuated resting posture is shared by a few other species of Ypsolopha, and most closely resembles Y. nemorella, which has a distinct dark spot on the forewing. Larva feeds on Spindle, beneath a silken web.

In Hampshire and Isle of Wight widespread but usually uncommon in woodland, principally in the south of our region. Wingspan 21-24 mm.

17.005 [B&F: 0455] Ypsolopha scabrella (Linnaeus, 1761) - Common
Common in gardens and open woodland throughout England and Wales, but less numerous in the northern uplands. Fairly well distributed, with a southerly bias, in Hampshire, but recorded very infrequently on the Isle of Wight. Wingspan 15-21 mm. Distinguished from all other Ypsolophinae by the three sets of raised scale tufts on the dorsal part of the forewing, but even when these have worn away, is still fairly unmistakable. Larva feeds on Hawthorn, Apple and Cotoneaster, beneath a silken web, over-wintering as an egg.

17.006 [B&F: 0456] Ypsolopha horridella (Treitschke, 1835) - Nationally Scarce B
Nationally scarce (Nb) in open woodland and gardens throughout southern England and northern Wales. Barely annual in Hampshire, where recorded widely, but only regular on the coast in the south-east of the county; very rare on the Isle of Wight. Wingspan 16-21 mm. Positioning and size of scale tufts on dorsum, and fuscous colouring distinguish Y. horridella from its congeners. Larva feeds on Apple and Blackthorn, beneath a silken web, over-wintering as an egg.

17.008 [B&F: 0458] Ypsolopha alpella ([Denis & Schiffermüller], 1775) - Local
Local in oak woodland throughout much of southern England and southern Wales, north to Yorkshire. Fairly frequent in south Hampshire, but uncommon in north Hampshire and on the Isle of Wight. Wingspan 14-18 mm. The main confusion species are Y. lucella, from which Y. alpella can be distinguished by the thorax being concolorous with the base of the forewing, and by the presence of fasciae, although on worn specimens these can be inconspicuous; and Y. sylvella from which Y. alpella can be distinguished by its smaller and less conspicuous fasciae, and by the paler ground colour of its forewing (MBGBI Vol 3). Larva feeds on Oak, beneath a silken web, over-wintering as an egg.

17.009 [B&F: 0459] Ypsolopha sylvella (Linnaeus, 1767) - Local
Local in oak woodland throughout much of southern England and Wales, with records north to Yorkshire. In Hampshire there is a scattering of records generally away from the chalk and concentrated in the south and south-west of the county. Apart from one, possibly unconfirmed, record from 2013, not seen on the Island since Victorian times. Wingspan 17-19 mm. Similar to Y. alpella, but generally darker with more obvious fasciae (MBGBI Vol 3). Larva feeds on Oak, beneath a silken web, over-wintering as an egg.
