New macro-moth checklist published

A list of all the species of larger (macro-) moths that have ever been recorded in Devon has been produced and is now available online. The list includes a total of 661 species, some residents others immigrant visitors, which comprises around two-thirds of the total number of macro-moths ever recorded in Britain and Ireland.

South Devon (Vice-county 3) has a total of 657 species recorded, but 26 of these have not been seen since at least 1960, so are either extinct former residents or rare migrants.

North Devon (Vice-county 4) has a shorter list of 575 macro-moth species with 21 not recorded since 1960.

While some moths have been lost from Devon, new species continue to be recorded, either as immigrants from overseas or due to spread from existing populations in neighboroughing counties. Recent additions include Jersey Mocha (Cyclophora ruficiliaria), first recorded in 2011, and Sombre Brocade (Dichonioxa tenebrosa), first seen in 2015, both of which may now be established in the county.

The new checklist was produced by Devon Moth Group Council member Phil Dean, assisted by County Recorder Barry Henwood, using information from the Group’s sightings database and from the 2001 book The Moths of Devon by Roy McCormick.
