2024 Annual Report for: Crambidae / Spilomelinae

For species seen in 2024 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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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 2024 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 2024, 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.

63.031 [B&F: 1395] Rusty-dot Pearl Udea ferrugalis (Hübner, 1796) - Migrant

Common immigrant to the British Isles from mainland Europe, most frequent on waste ground by the coast where sometimes abundant. In Hampshire and on the Isle of Wight a common immigrant, which is widely distributed throughout in some years. Wingspan 18-22 mm. The rusty forewing with prominent black discal spot is characteristic of this species [Goater]. Larva feeds on herbaceous plants.

63.032 [B&F: 1389] Udea fulvalis (Hübner, [1809]) - Migrant

Formerly considered a migrant to southern England from mainland Europe, in some years arriving in sufficient numbers to breed, it now has become established since the mid 1990s predominantly along the south coast of Hampshire inland into the New Forest, and along the north shore of the Isle of Wight; it is spreading northwards and has now reached the VC11/VC12 boundary, and one in the north-east in 2022 represents the first incursion from the Sussex heaths to the east. Wingspan 24-29 mm. Similar in structure, size and markings to U. prunalis, but differs in the dull fulvous brown coloration of the forewing, which is slaty grey in U. prunalis, and in the wider submedian sinus of second line [Goater]. Larva feeds on Black Horehound, Meadow Clary, Red Campion and White Campion.

63.033 [B&F: 1388] Udea lutealis (Hübner, [1809]) - Common

Common on waste ground, gardens and woodland edges throughout the British Isles. In Hampshire and on the Isle of Wight locally common to abundant, but scarce or absent in many places where, due to its polyphagous nature, it might be expected. Wingspan 23-26 mm. An easily recognised species on account of the pale coloration and dark clouding in apex of hindwing [Goater]. Larva polyphagous on various herbaceous plants, including Bramble, Thistle, Wormwood and Scabious.

63.038 [B&F: 1405] Mother of Pearl Patania ruralis (Scopoli, 1763) - Common

Common in rural gardens, waste ground and rough pastures throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 33-37 mm. One of the largest and most familiar pyralids, wings have an opalescent sheen, most obvious in sunshine, which gives rise to the vernacular name. Larva feeds predominately on Stinging Nettle, living within a spun or rolled leaf.

63.039 [B&F: 1396] Mecyna flavalis ([Denis & Schiffermüller], 1775) - pRDB2

Rare (proposed as a future Red Data Book species) on chalk downland and grassy slopes in parts of southern England, predominantly coastal. In Hampshire and on the Isle of Wight the species has two strongholds where it is common, on Porton, Broughton and Stockbridge Downs on the mainland, and Compton Down on the Island. Occasional specimens encountered away from these localities suggest that there may be other, perhaps small, colonies still undetected. Wingspan 25-29 mm. Both wings have a very narrow, dark terminal line and greyish cilia, producing a sharply pencilled outline to the wings which, together with the presence of a third stigmatal spot in the forewing, makes this species easy to recognise [Goater]. Larva feeds on Hedge Bedstraw, Field Woundwort, Black Horehound, Small Nettle and Mignonette.

Nationally scarce (Nb) on limestone downland and coastal cliffs in Britain, from Sussex to southern Wales, and in southern Ireland. On the Isle of Wight, frequent on the coast. In Hampshire although the foodplant occurs occasionally on the mainland, there are only a very few records of the moth. Wingspan 27-34 mm. Easily recognised by the long, pointed wings and soft blue-grey coloration [Goater]. Larva feeds on Wild Madder.

63.041 [B&F: 1410] Agrotera nemoralis (Scopoli, 1763) - pRDB1

Previously considered restricted as a breeding species in the UK to woodland in Kent, with occasional records from elsewhere as presumed migrants; however, in 2014 a breeding colony was found in Torpoint, Cornwall. In our area the only historic record dated from 1946, until another (illustrated here) was taken at MV by John Langmaid in Southsea on 4th June 2010. The first of Isle of Wight record was one to light in Borthwood Copse on 21st June 2015, since when it has been taken annually, indicating probable colonisation of the south-east of the island. Still rare on the mainland, there have been four reports since 2018, which may relate to dispersion across the Solent; remarkably far inland, one turned up in Alton (VC12) in 2023. Wingspan 20-24 mm. Unmistakable. Larva feeds on Hornbeam and Hazel.

63.046 [B&F: 1403a] Duponchelia fovealis Zeller, 1847 - Migrant/Adventive

Suspected rare immigrant, or perhaps accidentally imported, from southern Europe and most frequently recorded in houses, garden centres, nurseries and glass houses. In Hampshire first recorded in 1999, with recent years seeing scattered records across the county, and two from the Isle of Wight. Despite the first report being at MV light, half the twenty or so county records since have been indoors, indicating that the majority, if not all, records are likely to originate from imported plant material. Wingspan 19-21 mm. Unmistakable.

63.047 [B&F: 1404] Spoladea recurvalis (Fabricius, 1775) - Migrant

Rare immigrant to southern England from southern Europe. Formerly an accidental import in vegetables from tropical Africa, increasingly seen as an immigrant from mainland Europe. First recorded in Britain in Surrey and Dorset in September 1951, with 19 up to the end of 2005 but 2006, an exceptional year for migrants, saw 18 alone. In Hampshire recorded for the first time in October 2011, when individuals turned up on Hayling Island and in Southampton, and the third record for our area was in Bonchurch, Isle of Wight, in 2013. North Hampshire's first record was in Leckford on 31 Oct 2014, and a further Isle of Wight individual was recorded in Totland on 18 Dec 2015, part of that year's extraordinary late December migrant influx. Wingspan 22-24 mm. Similar to Diasemia reticularis and Diasemiopsis ramburialis, which both have chequered fringes. Larva feeds on fruits and vegetables, causing sufficient damage to be a serious pest on spinach, beet, cotton, maize and soya in some areas; no evidence of breeding in the UK.

Nationally scarce (Nb) on cliffs and shingle beaches in England, from Sussex to Cornwall and the Isles of Scilly, predominantly coastal. In Hampshire and on the Isle of Wight local and uncommon on the coast. Wingspan 20-25 mm. The long legs and antennae give the species a distinctive jizz; in the superficially similar Synaphe punctalis, the discal spot is dark and the second line is clearly pale-edged distally [Goater]. Larva feeds on flowers and leaves of plants such as Bird's-foot Trefoil, Red Clover and Buckshorn Plantain.

63.052 [B&F: 1398] Rush Veneer Nomophila noctuella ([Denis & Schiffermüller], 1775) - Migrant

Common immigrant from mainland Europe, appearing throughout the British Isles, abundantly in some years, but most frequently and numerously in the south. In Hampshire and on the Isle of Wight a common immigrant, which is widely distributed throughout in some years. Wingspan 25-34 mm. Until recently, this was regarded as an absolutely unmistakable species, but it is now known to comprise a species complex of considerable size, one of which, N. nearctica, has been recorded in Britain. Larva feeds on Leguminosae, over-wintering as a pupa.

63.054 [B&F: 1409a] Box-tree Moth Cydalima perspectalis (Walker, 1859) - Adventive

A native to Asia, and after an initial finding in Germany in 2007, it has been found elsewhere in Europe, thought that the species was originally introduced with imports from China. Since the first finding, larvae have been found in more locations across Germany, sometimes causing severe defoliation as they feed on box (Buxus sp.). By 2008, C. perspectalis had been reported from five countries in Western Europe. In England, it was first recorded in 2008, when adult moths were caught in light traps at Icklesham, East Sussex, and Weybridge, Surrey. In 2009 a nursery in Surrey found perspectalis larvae causing severe damage.

In 2013, a large infestation was discovered at Longstock Nursery in central Hampshire, from which a number of adults were bred. In the same year, a few individuals were caught in the wild, provenance unknown, and it was new for Hampshire and the Isle of Wight in the same year.

As can be seen from the annual distribution graph, a resident population became established around 2016-2017, and numbers are increasing significantly each year. In southern Hampshire in particular it can be one of the most abundant species to light for some unfortunate recorders.

Wingspan 38-42 mm. Somewhat variable, but typical form unmistakable, and there is an attractive purple-black melanic form which is not uncommon. Larva feeds on Box, and may become a horticultural pest in the UK.
