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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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.
Local in woodland and rough meadows throughout much of the British Isles. In Hampshire cases can be found in woodland, on rocks and old walls, and are widespread and common on the mainland, although there are no recent record from the Isle of Wight. Wingspan male 15-20 mm, female wingless. The adult moths are seen occasionally, but most records are of larval cases. Larva feeds on various lichens, dead insects and decaying vegetable matter, living within a movable case, over-wintering once or twice. The case is constructed of silk coated with lichen, fine sand and bark, and can be found.

Endangered (proposed as a future Red Data Book species) in Hampshire and Kent, where it was rediscovered in 1984, and Yorkshire; recently also found in an urban context in Mynachdy, Cardiff. Not recorded from the Isle of Wight to date. There has been some discussion amongst authors as to the identity of the species found in Britain; formerly it was believed to be Dahlica (Bankesia) douglasii, but presently it is assigned to B. conspurcatella. The adult moths are seen occasionally, but most records are of larval cases. Larva feeds on lichens growing on tree trunks, fence posts and rocks, living within a movable case, over-wintering as a pupa.
