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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
Common in oak woodland throughout the British Isles, excluding northern Scotland. Well distributed and by far the most common Eriocrania: the overwhelming majority of individuals in garden light traps turn out to be this species. It can be abundant wherever there are oak trees. Wingspan 9-14 mm; a diurnal species which is also attracted to light, in dull weather it rests on the trunks and branches of oak trees. The metallic gold forewing is speckled with minute purple or blue spots. Larva mines leaves of Oak, over-wintering as a pupa.

Local in woodland, hedgerows and scrub in southern England and also the Burren in Ireland. In Hampshire very local in deciduous woodland, particularly from Botley Wood, where it still occurs, and there are scattered records across the county, particularly around Fleet and the Blackwater area.The first record from the Isle of Wight came in 2020. Wingspan 9-13 mm. Very similar to E. cicatricella from which separated only by dissection of the genitalia. Larva mines leaves of Hornbeam and Hazel, over-wintering as a pupa.

Local in birch woodland throughout most of Britain. In Hampshire and on the Isle of Wight local and evidently rather uncommon amongst birch, most frequently in thr south and north-east of Hampshire. Wingspan 9-11 mm. This species is most easily distinguished from other Eriocrania by the conspicuous silvery tornal spot, which in most other species is pale golden (MBGBI Vol 1). Larva mines leaves of Birch, over-wintering as a pupa.

Local in birch woodland throughout the British Isles. In Hampshire and on the Isle of Wight local and evidently rather uncommon amongst birch, most frequently in southern Hampshire. Wingspan 10-13 mm. E. salopiella has a similar pattern and wing shape but is normally suffused with purple and bright blue (MBGBI Vol 1). Larva mines leaves of Birch, over-wintering as a pupa.

VC11: Botley Wood, mine, present, 24 Jun (DPH)
Local in birch woodland throughout Britain, with a scattered, discontinuous distribution. The distribution in Hampshire and on the Isle of Wight follows a similar pattern to other Eriocrania, being mainly restricted to the woodlands of the south, along the north edge of Wight, and around the north-eastern heaths. Wingspan 9-12 mm. Day-flying. Adults difficult to distinguish from other Eriocrania species, and more reliably recorded in the larval stage. Larva mines leaves of Birch, over-wintering as a pupa.
