Norfolk Moth Survey c/o Natural History Dept., Castle Museum, Norwich, NR1 3JU Newsletter No.79 April 2011 INTRODUCTION Following the cold winter, we have already experienced some warmer days – and a few warmer nights, of course – as the new season gets underway again. Some recorders have reported reasonable catches, and some very interesting records. As well as a goodly number of Small Eggar sightings, two of the micros, Pammene giganteana and Acleris literana, are respectively the first and second Norfolk records for about a century. So far, we have two new additions to the county list to report, Ectoedemia heringella and Ocnerostoma friesei. The first of these is a leaf miner on holm oak, which apparently only arrived in Britain in 2002. It has been spreading slowly ever since and is well worth keeping a lookout for. Some exciting records have also been forthcoming following recent re-examination of some of the lepidoptera collections housed at the Castle Museum. These include a stunning specimen of Argent & Sable, bred from Costessey in 1935, together with confirmation of a couple of specimens of the rarer Cnephasias – pasiuana and conspersana. As well as the collections per se, it has been interesting to learn a bit about the lives of some the earlier entomologists working in the county. If they were alive today, I feel sure they would have been involved with NMS! Jim Wheeler has added some information to the website. Please go to www.norfolkmoths.org.uk/collections.php We must also add our thanks for all his help to Tony Irwin at the Castle. As usual, Dave Hipperson has compiled an update to the list of migrant records from last year. If you still have any outstanding records, then please do submit them. Last year, Norfolk Wildlife Trust organised a Big Biodiversity Watch to record species over a twenty-four hour period on their nature reserves in the county, and some of you helped with moth recording as part of this event. This year a Big Urban Biodiversity Watch is being planned for the weekend 4/5 June, with (as the name implies) an Contents: emphasis on recording wildlife in Introduction Ken Saul page 1 more urban areas.

Once again, any offers of help with Advertisement page 14 moth recording will be gratefully Norfolk Moths Website details page 14 received. Please contact Andy Photographs page 15 Musgrove at [email protected] Norfolk Moth Survey Newsletter 78 Page 1 of 16 As you will know from previous articles in this newsletter, insects other than moths are frequently attracted to our lights. And, dare I say this, some of them have proved to be more exciting than some of the moths! We have received a request from Doreen Wells, the County Ant Recorder, to please collect any specimens of flying ants that come to our traps. Last year, a rare species of parasitic ant was discovered in the county, and Doreen is keen to discover what else may be around, especially during July and August. She is more than happy to return pots and pay any postage costs incurred. Please send any captured specimens to:- Doreen Wells, 1 Cobden Terrace, Northgate Street, Great Yarmouth, Norfolk, NR30 1BT. Alternatively, material can be left with the Natural History department at the Castle Museum. We hope that you will find much to inspire and instruct among the other articles in this newsletter. It is really very encouraging to know of all the other mothing activities that our recorders are involved with, often quite informally, alongside the events that are organised by NMS. We include here a piece about the activities of one group active in mid-Norfolk, and hope to continue this as a series looking at what various groups and individuals get up to. We would be very pleased to receive news from anyone willing to write something about their moth recording experiences. For the first time in many years there will be no National Moth Night this year. For various reasons the organisers have decided to give it a miss this time, though hopefully with a return in 2012. However, we have arranged our series of field meetings throughout the county as usual, which you are all welcome to attend. As always, we hope that these events provide a good opportunity to learn more about the county‟s moths, their identification and habits, as well as helping to increase our recording effort. They are free of charge, but we have to advise that attendance is at the individual‟s own risk, and that suitable attire should be worn in case of inclement weather, difficult ground conditions, etc. We must also remind you that the actual trapping site can sometimes be a little distance from the parking/meeting grid reference, so please make sure that you arrive on time if you are unfamiliar with the area. Full details of the meetings are as follows:- Saturday 28 May Roydon Common Meet 8.30 pm in the NWT car park at the western end of the reserve at TF680229. Saturday 4 June Emily’s Wood, Weeting Meet 8.30 pm. Turn off the road to park beside the rough track at TL797901. Saturday 25 June Weston Park Meet 8.30 pm at the old dairy farm at the bottom of the park TG106170. Hopefully this should be signed on the night.

Norfolk Moth Survey Newsletter 78 Page 2 of 16 Wednesday 9 November Our Annual Review Meeting 7.30 pm in the Orchard Room at Mangreen Hall, TG215030. Please join us to share and discuss the highlights of the year, and bring along your pics (please let us know if you intend to bring slides and we‟ll provide a projector, these days it is mostly digital), specimens, and exciting news. In order to cover costs we have to charge £3 for this meeting, but that does include a cup of tea or coffee and a piece of home-made cake! There are usually various other mothing events taking place around the county that are not organised by NMS, but that many of you are frequently involved with. We are always pleased to publish details of these if you let us know about them. Jon Clifton will be leading a moth evening at the Hawk & Owl Trust reserve at Sculthorpe Moor on Saturday 11 June, while the regular National Trust bat and moth night at Sheringham Park takes place on Friday 1 July. As usual, this latter is a paying event for the public, but NMS recorders with moth traps are always freely welcome. The Broadland group of NWT hold their annual moth night at Hickling Broad on Friday 26 August, meeting at 8.30 pm in the reserve car park at TG428221. On Thursday mornings (weather permitting) from the end of April, Norfolk Wildlife Trust will be running a moth trap at Cley NWT behind the visitor centre which will be opened at 9.00 am. Anyone is free to attend and any help will be gratefully received, especially in identification! If you are in the area or intending to come please ring the NWT Cley visitor centre on 01263 740008 on the Wednesday afternoon to check if the trap will be run. Natural Surroundings will also be running evening events during the summer at Natural Surroundings, between Letheringsett and Glandford where again, besides a Bar BQ, a couple of moth traps will be run during the evening. Please ring Natural Surroundings on 01263 711091 for prices and bookings:- Easter Sat 23April; Sat 28 May; Fri July 1, NWT members evening; Weds 3 Aug; Weds 17 Aug; Sat 27 Aug Bank Holiday weekend trap and BarBQ. So once again we look forward to some decent weather and plenty of activity recording and studying the moths of Norfolk.
