History

The first record for Kirkcudbrightshire, D&G and Scotland was one trapped at Rockcliffe on 25 October 2017. The first for Dumfriesshire was at Glencaple on 12 October 2018. There were two other records, both in VC73, in the decade 2010-2020.

This species, once restricted to southern and central England and Wales, increased in abundance and spread into northern England in the early 21st century. It is expected to continue to spread in Scotland.
