2020 Annual Report for: Drepanidae / Thyatirinae
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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
65.008 [B&F: 1652] Peach Blossom Thyatira batis (Linnaeus, 1758) - Common
Common in scrub, hedgerows and gardens throughout the British Isles. In Hampshire and on the Isle of Wight fairly common, especially in open deciduous woodland where there is a good cover of Bramble. Wingspan 39-44 mm. The pink and brown petal-like markings on forewing are diagnostic (MBGBI Vol 7 part 2). Larva feeds on Bramble, over-wintering as a pupa.

65.010 [B&F: 1654] Figure of Eighty Tethea ocularis (Linnaeus, 1767) - Common
Common in broad-leaved woodland, plantations, parks, hedgerows and gardens throughout much of England. In Hampshire and on the Isle of Wight widespread and common in all three vice-counties. Wingspan 36-44 mm. Poplar Lutestring T. or is of similar size and shape, however in that species the white 80 mark is less clearly defined, often obsolete, there are four parallel fasciae in the antemedian region of the forewing, and the antemedian and postmedian lines diverge as they approach the costa instead of being parallel (MBGBI Vol 7 part 2). Larva feeds on Aspen and Poplar, over-wintering as a pupa.

65.011 [B&F: 1655] Poplar Lutestring Tethea or ([Denis & Schiffermüller], 1775) - Local
Local in broad-leaved woodland throughout much of southern England and Wales; also in Ireland and Scotland, where represented by different subspecies. In Hampshire and on the Isle of Wight clearly much more local than Figure of Eighty, but found wherever Aspen is established. Wingspan 38-43 mm. The most likely confusion species is Figure of Eighty T. ocularis, which see for differences. Larva feeds on Aspen, over-wintering as a pupa.

65.012 [B&F: 1656] Satin Lutestring Tetheella fluctuosa (Hübner, [1803]) - Local
Local in broad-leaved, especially birch, woodland and heathland throughout England and Wales. In Hampshire the population is centred in the extreme south-eastern corner of vice-county 12 (north Hampshire), with scattered records in south Hampshire and on the Isle of Wight. Wingspan 35-38 mm. The main confusion species is Common Lutestring Ochropacha duplaris, which differs, for example, in the small apical dash, which originates at the apex in Common Lutestring, and some way down the costa in Satin Lutestring. Larva feeds on Silver and Downy Birch, over-wintering as a pupa.

65.013 [B&F: 1657] Common Lutestring Ochropacha duplaris (Linnaeus, 1761) - Common
Common in woodland, scrub, heathland and gardens throughout the British Isles. Widespread and common in Hampshire, but rather scarce on the Isle of Wight, with just two records there so far this century. Wingspan 25-34 mm. The main confusion species is Satin Lutestring Tetheella fluctuosa, but differs, for example, in small apical dash, which originates at the apex in Common Lutestring and some way down the costa in Satin Lutestring. Larva feeds on Silver and Downy Birch, over-wintering as a pupa.

65.014 [B&F: 1658] Oak Lutestring Cymatophorina diluta ([Denis & Schiffermüller], 1775) - Local
Local in mature oak woodland throughout England, also appearing in some rural gardens, a species of conservation concern under the UK Biodiversity Action Plan. Sparsely recorded, and decreasing, away from extensive woods, but still reasonably common in suitable habitat in Hampshire and the northern half of the Isle of Wight. Wingspan 33-36 mm. The only thyatirid with two distinct brown fascia. Larva feeds on Pedunculate Oak and Sessile Oak, over-wintering as an egg.

65.016 [B&F: 1659] Yellow Horned Achlya flavicornis (Linnaeus, 1758) - Common
Common in woodland, and on heathland and moorland throughout England and Wales. In Hampshire and on the Isle of Wight common in birch areas, especially on the heathland of the New Forest and in the north-east, but in many areas it has suffered from loss of habitat to housing development. Wingspan 39-44 mm. Characterised by orange coloration of antennae. Larva feeds on Downy and Silver Birch, over-wintering as a pupa.
