2023 Annual Report for: Crambidae / Pyraustinae
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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
63.002 [B&F: 1368] Loxostege sticticalis (Linnaeus, 1761) - Migrant
Irregular immigrant to the British Isles from southern Europe, common in some years. In Hampshire and on the Isle of Wight most frequent on the coast, but very irregular in appearance, with a notable influx in 1995 when at least 12 were recorded. Most common in the south, where it is nearly annual, reports from the north are very rare, with only four to date: one in 2022 was the first for 21 years (five individuals were reported in VC12). Wingspan 24-29 mm. Most likely to be confused with the abundant Udea olivalis, but distinguished by the characteristic white terminal streak. Larva feeds on Mugwort, over-wintering as a pupa.

63.004 [B&F: 1364] Pyrausta sanguinalis (Linnaeus, 1767) - pRDB1
Endangered (proposed as a future Red Data Book species) in sand-dunes and on limestone pavements in parts of western Ireland, northern Wales and the Isle of Man, predominantly coastal, a priority species under the UK Biodiversity Action Plan. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 14-18 mm. Somewhat variable in the brightness and contrast of the markings, but unlikely to be confused with any other British Pyrausta [Goater]. Larva feeds on Wild Thyme.

63.006 [B&F: 1361] Pyrausta aurata (Scopoli, 1763) - Common
Local, on chalk downland and open, grassy areas, discontinuously throughout much of England, Wales and southern Scotland. In Hampshire and on the Isle of Wight, sometimes abundant on the downs, but also in gardens amongst cultivated mint. Wingspan 15-18mm. Flies by day and night. The main confusion species is P. purpuralis which is larger and occurs less frequently in gardens. P. aurata has fewer cream spots on the forewing and the spot near the dorsal edge is either absent or small and broken into three parts. P. purpuralis has a rounded leading edge to the dorsal cream spot. Note that the purple scales apparent when freshly emerged quickly wear off and leave just a brown appearance. Larva feeds on Mint, Marjoram and Thyme, living within a silken tube or tent.

63.007 [B&F: 1362] Pyrausta purpuralis (Linnaeus, 1758) - Common
Found on chalk downland and dry, grassy areas, throughout much of Britain favouring very short turf. In Hampshire and on the Isle of Wight, locally common on the downs, and sometimes found in gardens where Thyme is grown. Wingspan 15-22mm. Flies by day and night. At first glance, confusable with P. aurata, from which distinguished by its larger size and the rounded leading edge to the dorsal cream spot on the forewing. The hindwing always has one or two yellow spots or short, broad streaks; this is best seen by viewing the underside of the moth. Also see the very similar P. ostrinalis for differences. Note that the purple scales apparent when freshly emerged quickly wear off and leave just a brown appearance. Larva feeds on Wild Thyme and Large Thyme and sometimes Corn Mint, living within a silken tube or tent.

63.013 [B&F: 1387] Nascia cilialis (Hübner, 1796) - Nationally Scarce B
Nationally scarce (Nb) in marshes and fens and along freshwater margins in the Cambridgeshire fens and, very locally, in Hampshire. In Hampshire still regular in and around Titchfield Haven, with occasional wanderers elsewhere; recently found in the Afton Marsh area of the Isle of Wight and undoubtedly now resident there. Wingspan 24-27 mm. An easily recognised species, though it could conceivably be confused with the scarce immigrant Antigastra catalaunalis [Goater]. Larva feeds on Greater Pond-sedge

63.014 [B&F: 1370] Sitochroa palealis ([Denis & Schiffermüller], 1775) - Local
Local on heathland, downland, waste ground and cliff-tops throughout much of southern England and East Anglia. In Hampshire and on the Isle of Wight an immigrant which has become established; since 1990, singletons have been seen regularly, and breeding colonies are established, perhaps temporarily, in several localities on the coast and across the chalk downland. Wingspan 29-34 mm. Fairly unmistakable: pale sulphur-yellow when fresh, fading whiter with age, but always with prominent veins. Larva feeds on flowers and seeds of Fennel, Wild Carrot, Pepper-saxifrage, Hogweed and other umbellifers.

Common on rough ground and in gardens throughout England, Wales and Ireland. In Hampshire and on the Isle of Wight common wherever elder flourishes, and occasionally recorded away from the foodplant. Wingspan 23-26mm. The main confusion species is the far rarer P. stachydalis, which differs, for example, in the distinctly irregular distal edge of the large white spots on the hindwing and forewing — in P. coronata these white spots are neatly delineated and circular — and the slightly falcate wing-tip of P. stachydalis. Larva feeds on Elder, living within a spun or rolled leaf.

63.020 [B&F: 1380] Anania perlucidalis (Hübner, [1809]) - Common
A species of fens and reed-beds, damp meadows and wasteground. In Hampshire and on the Isle of Wight, first recorded in the county in 1973, but not seen again until 1988. Since then, it has become established and is evidently spreading, though still at low density; most commonly found in the Test valley above Stockbridge, with scattered records elsewhere. Wingspan 21-23 mm. Prominent dark discal spot precludes confusion with any other species [Goater]. Larva feeds on Thistle Carduus/Cirsium.

Local in water meadows, marshes, river-banks and damp areas throughout much of England and Wales. The most likely confusion species is Udea lutealis, in which the cross-lines are more intricately sinuate, the stigmata are larger and clearly outlined, and there is a dark cloud in apex of hindwing [Goater]. Could also be mistaken for the extremely rare Paracorsia repandalis. Wingspan 22-25 mm. Larva feeds on Common Fleabane and Ploughman's-spikenard, living between leaves spun together with silk.
