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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
Common near buildings and around dry-stone walls throughout England, Wales and southern Ireland. Widespread and common in Hampshire. Recorded on the Isle of Wight for the first time since 1893 at Freshwater in 2009. Wingspan 11-14 mm. A light coloured species with slender forewing, contrasting markings and with the first discal above the second plical stigma, extremely pale forms of B. dryadella are distinguished from B. domestica by the much darker hindwing (MBGBI Vol 4 part 2). Larva feeds on various mosses, often on walls, living within a silken gallery.

Common in grassland and mossy areas throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 13-17 mm. A plain brown micro and therefore decidedly overlooked and under-recorded, the main confusion species are B. desertella and B. politella, but these are both extremely rare in Hampshire. Larva feeds on various grasses and mosses, living within a silken tube or tent.

Nationally scarce (Na) in urban areas and on old buildings in southern England. First recorded in South Hampshire in 2013, and found on the Hampshire/Surrey border in North Hampshire in 2023. While occasionally reported, records are often unsupported by sufficient evidence to allow acceptance; it is probably under-recorded as very similar to B. dryadella and often only separable by dissection of the genitalia, however shape of fascia is straight or slightly inwards-bent in B. dryadella, but slightly outwards-bent and rarely straight in B. basaltinella (MBGBI Vol 4 part 2). Larva feeds on various mosses, living within a silken tube or tent.

Local in urban areas, old buildings and rocky areas throughout the British Isles, except for the Highlands and Islands of Scotland. In Hampshire frequent only in the south-east, and very much less common elsewhere in the county and on the Isle of Wight. Wingspan 9-13 mm. The brown colour and the dark line running over the vertex of the head distinguish B. senectella from similar looking species, but very dark forms resemble B. similis; in case of doubt, they can be separated by the pale yellow labial palpus and frons of B. senectella (creamy white in B. similis). Larva feeds on various mosses, living within a silken tube or tent.

Not recorded from the Isle of Wight since 1975. Wingspan 12-13 mm. Flies in afternoon, and occasionally comes to light. One of the more distinctive gelechiids, unlikely to be confused with any other species. Larva feeds on Heather, living between shoots spun together with silk, and over-wintering as an egg.

Local on downland, rough ground, dry pastures and in woodland clearings throughout much of England and Wales; rare in Ireland. In Hampshire widespread and common; on the Isle of Wight, first recorded at Cranmore in July 2001. Wingspan 11-13 mm.
