CHESHIRE (VICE COUNTY 58) MOTH REPORT FOR 2017 Lobster Moth: Roger Parry Authors: Steve H. Hind and Steve W. Holmes Date: 10th March 2018 Cheshire moth report 2017 Introduction Weather conditions were generally favourable for moth recording during the first half of the year resulting in a number of interesting discoveries and some good catches but the summer was unfortunately cool and unsettled. Five new species were added to the county list during the year, with the first two of these during a hot spell of weather in late May: Lobster Moth Stauropus fagi on 25th May and Assara terebrella on 27th May. Stigmella svenssoni followed on 16th June, with Anania lancealis on 30th June and the first of three Box-tree Moths Cydalima perspectalis on 6th July. 954 species were found during 2017, a new record annual count for Vice County 58, Cheshire, 19 more than last year’s previous record and these from over 70,000 records received. This is only the second time we have passed this figure, so thanks to everyone for sending in their records and photographs, making the production of this report possible. As always, a list of those species new for their respective 10km squares during 2017 can be found after the main report. Work continued during the winter to add historical records from the collections at Manchester Museum, past entomological journals and recorders old note books, which is enabling us to compare our current data with that of the past and this year we have included some additional comments within the species section of the report putting into context some of the years sightings. The map above shows the number of species recorded in each hectad (10km*10km square) during 2017 to illustrate the recording coverage across the county. We managed to increase the number of species recorded in 20 hectads during the year, most significantly in SJ37 (Ellesmere Port), where exactly 100 additional species were recorded compared to 2016 and in SJ86 (Congleton) which was targeted specifically to improve the micro- moth coverage and produced an additional 240 species. However numbers were down in 23 hectads, due in a few cases to regular recorders either not trapping during the year, or not P a g e 2 | 66 Cheshire moth report 2017 submitting their records in time for inclusion within the report. Most moth trapping continues to be carried out in recorders gardens and although we currently have a good spread of recorders across the county, there remain hectads without a resident trapper. Knowledge on the status of our garden moths is increasing each year but trapping away from our gardens is still very limited, so visits into the wider countryside is likely to produce the most significant rewards. Time and effort dictate that this report cannot be a complete analysis of the years’ records; it does however itemise all macro-moth species that were recorded fewer than 10 times during the year as well as the most notable micro-moths. Throughout what follows, header information relating to each species comprises: 3.004 Gold Swift Hepialus hecta (Linnaeus, 1758) Which, reading left to right detail: Incoming Agassiz, Beavan & Heckford species number Species’ vernacular name Species’ taxonomic name Species’ Author(s) Species distribution maps have been deliberately omitted from this years’ report as we have been involved with and are anticipating the on-line publication of an e-atlas for every species within the county in the not too distant future.
