2021 Annual Report for: Crambidae / Musotiminae

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taken from the main Hantsmoths website, and it is possible that some information on abundance and occurrence can get out of date, as it is impossible to keep up with all changes; however it should give a good introduction to each species.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

63.119 [B&F: 1355a] Musotima nitidalis (Walker, [1866]) - Adventive

First trapped at Merritown Heath, Dorset on 11 August 2009 by Mike Jeffes and David Evans, and identified at the BENHS Exhibition that year by Martin Honey (BMNH) as the present species, a native of New Zealand which feeds on various fern species. Certainly introduced by the horticultural trade, it has since spread widely, with multiple sightings from other sites close to the original trapping location and in Hurn Forest (in Dorset, but in the VC11 South Hampshire vice-county), but also as far as East and West Sussex, and Harlow in Essex. Unmistakable.
