2023 Annual Report for: Noctuidae / Plusiinae

For species seen in 2023 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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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 2023 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 2023, 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.

73.010 [B&F: 2436] Dewick's Plusia Macdunnoughia confusa (Stephens, 1850) - Recent colonist

Rare immigrant from mainland Europe, appearing in south-eastern England for the first time at Bradwell-on-Sea, Essex, on 3 October 1951. From about 1920 had spread rapidly into Western Europe from the central Palaearctic, and has been seen increasingly in Britain, especially in the last ten years. In Hampshire and on the Isle of Wight recorded for the first time in August 1991, and then again in 1998, 1999 and 2001 (the first for Wight); 2003 to 2006 saw a further six, with another six in 2007, 11 in 2008 and another six in 2009. This pattern has been maintained up to the present year and increasingly extending its range into the north of the county, which may be originating from the London population spreading west. Wingspan 32-38 mm. Fairly distinctive. Larva feeds on herbaceous plants such as Stinging Nettle, Yarrow, Corn Chamomile, Stinking Chamomile and Wormwood; breeding has been confirmed in Middlesex and is probably established elsewhere.

73.011 [B&F: 2435] Scarce Burnished Brass Diachrysia chryson (Esper, 1798) - Nationally Scarce

Nationally scarce (Na) in river valleys, marshes, fens and damp woodland in southern England and South Wales. In Hampshire the headquarters of this nationally very local species are in the Test valley north and south of Stockbridge; there is another colony in the Winchester area, in the valley of the Itchen. Not recorded from the Isle of Wight to date. Wingspan 44-54 mm. The most likely confusion species is the far more common Burnished Brass Diachrysia chrysitis which has the basal portion of the metallic patch extending from costa to dorsum, in Scarce Burnished Brass this patch is squarish and limited to the apical area (MBGBI Vol 10). Larva feeds on Hemp-agrimony growing in carr and along the margins of fen woodland but not, apparently, in dry places.

73.015 [B&F: 2441] Silver Y Autographa gamma (Linnaeus, 1758) - Migrant

Common immigrant from mainland Europe, appearing throughout the British Isles, in most years arriving in sufficient numbers to breed. In Hampshire and on the Isle of Wight sometimes abundant, with numbers boosted, in good years, by the offspring of earlier migrants. Wingspan 40-48 mm. A familiar and conspicuous moth, often seen by day nectaring in a wide range of habitats, when confusion with Humming-bird Hawk-moth Macroglossum stellatarum is possible. Larva polyphagous on plants such as Stinging Nettle, Hedge Bedstraw, Clover, brassicas and legumes, causing sufficient damage to be a serious pest in some areas; unable to over-winter in significant numbers.

The main confusion species is Plain Golden Y A. jota, in which reniform stigma is indistinct or absent. Larva feeds predominantly on Stinging Nettle, but also on Hedge Woundwort, Common Ragwort, Water Avens and Honeysuckle.

73.022 [B&F: 2439] Gold Spot Plusia festucae (Linnaeus, 1758) - Common

Common in marshes, fens, woodland rides and upland grassland, and on heathland, moorland and river-banks throughout the British Isles. In Hampshire and on the Isle of Wight an uncommon resident, mainly in coastal marshes and less commonly in the river valleys, occasional wanderers may turn up elsewhere. Wingspan 35-40 mm. The main confusion species, Lempke's Gold Spot P. putnami, is rare in the south of England, and differs in having the more distal of the silver median spots smaller and more rounded, and the subapical silver streak shorter and thicker, but can often only be separated by dissection of the genitalia. Larva feeds on various sedges, including Tufted Sedge and Glaucous Sedge, and other waterside plants.
