2021 Annual Report for: Adelidae / Adelinae

For species seen in 2021 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is taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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 2021 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 2021, 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.

07.007 [B&F: 0149] Adela cuprella ([Denis & Schiffermüller], 1775) - Local

Local on heaths, fens and woodland in southern Britain, as far north as Sutherland. In Hampshire and the Isle of Wight very local in damp areas where Salix is plentiful, most notably in and around Pamber Forest. Wingspan 14-16 mm. Adult males have a hairy black head and long white antennae, which are quite visible with binoculars, as they fly often in small groups with their characteristic dancing flight over the tops of male Salix bushes. Females have shorter dark antennae with a yellowish/orange head and come lower down to lay on the catkins. Larva feeds on fallen leaves under Sallow, living within a movable case, over-wintering twice.

Local in woodland, fens, marshes and bogs throughout much of England and Wales. In Hampshire and on the Isle of Wight there are scattered records from all three vice-counties. Wingspan 15-17 mm. This species may be confused with N. schwarziellus or N. pilella, but may be recognised by its more rounded wings and more prominent dark mark at the end of the cell of the forewing (MBGBI Vol 1). Larva feeds on dead leaves, living within a movable case.
