Announcing Berkshire macro-moth no. 643!

Bernard Clark becomes the first person to add a new species to the county list in 2020, bringing our all-time macro-moth total to 643. On 1 July 2020 Bernard's moth trap in Maidenhead was graced with the spectacular Passenger moth, Dysgonia algira. This is a rare migrant in Britain, with only one or two individuals seen anywhere in the country in most years. Its caterpillars feed on bramble and its range is apparently expanding on the continent so perhaps it is a moth we will see more of in the future.
