Not only were the numbers reduced but there were only two new species added to the Channel Islands list from Guernsey. The following is a summary of the moths and butterflies recorded in the Bailiwick of Guernsey during 2012. The summary includes both light trap records and sightings by myself together with all other records passed on to me by other recorders. In particular I would like to thank Trevor Bourgaize, Jane Cleal, Peter Costen, Mark Lawlor, and Wayne Turner. I have also included records from the Rothamsted trap and would like to express my thanks to the staff at Plant Health Services for continuing to set and empty the trap. Alderney continues to be extremely well recorded by David Wedd and a complete summary for both the micro and macro moths can be found on the Alderney Record Centre web site and I see no point in duplicating this information. We were not lucky enough to have any visiting lepidopterists and so the few records we did receive from Sark were made by locals making a day visit. As we are now getting so few records from the other islands in the Bailiwick I have omitted the “Guernsey’ heading under each species but have added ‘Sark’ where casual records have been received. The butterfly recorders continue to provide records and I would particularly like to thank Ian Hall, Chris de la Mare and Andy Smith for their excellent work as well as all the birdwatchers who log their records on the Guernsey Birds web site. I would like to take this opportunity to thank everyone who has taken the trouble to pass on their records. In this rapidly changing world it is only by keeping good records that we can monitor changes. Where monthly counts are given for species these are not necessarily exact totals but are intended to give a good indication of flight times and/or relative monthly abundance and refer to Guernsey records only. The order and species numbers used in the summary are as used by J. D. Bradley in 'Checklist of Lepidoptera Recorded from the British Isles' published in 1998 and incorporating subsequent updated nomenclature published in various journals. Taxanomic changes have taken place since Bradley and Fletcher originally assigned each species an identifying number but, for ease of reference, I have kept the list in strict numerical order. The only two species added to the island lists were as follows:- New Channel Islands Records:- 0330 Phyllonorycter cerascicolella (H.-S.) 0407 Argyresthia dilectella (Zell.) 1 Moths and Butterflies of Guernsey 2012 List of Contributors:- Margaret Austin (MA) Rich Austin (RA) Tony Bisson (AJB) Terry Brokenshire (TB) Trevor Bourgaize (TJB) Kevin Childs (KC) Jane Cleal (JC) Peter Costen (PC) Tim Earl (TDCE) Vic Froome (VF) Mark Guppy (MAG) Ian Hall (IH) Tracy Henry (TH) Jamie Hooper (JH) Carole Kinnersley (CK) Mark Lawlor (MPL) Suzi Macdougall (SM) Chris de la Mare (CDLM) Bob Murphy (RJM) Nigel Pletts (NP) Gary Prince (GP) Andrew Smith (AS) Mary Simmons (MCS) Liz Thomson (LT) Wayne Turner (WRT) Brief description of light trapping sites in Guernsey:- St. John, St Peter Port A small urban garden close to the east coast.
