Norfolk Moth Survey c/o Natural History Dept., Castle Museum, Norwich, NR1 3JU Newsletter No.82 November 2012 INTRODUCTION It has been, as they say, a funny old year. Anyone hoping for an upturn in mothing fortunes following the topsy-turvy summer of 2011 was likely to have been disappointed. In fact, I don’t think I can recall any other year since NMS started in 1985, when so many of our planned field meetings have succumbed to adverse weather conditions. Lynford was postponed, Brettenham was a non-event, and our joint meeting with the Suffolk Moth Group for National Moth Night was cancelled. One suggestion resulting from all this is that in future we should encourage everyone to check information on the website on the day of the event if conditions are likely to be unfavourable. Hopefully that may prevent un-necessary journeys from being undertaken. Having said all that, the remaining field trips were fairly successful, and reports on them are included in this newsletter. As always, we are grateful to all of you who have supported these events in any way. Given the circumstances, it is hardly surprising that migrant species were also relatively sparse in appearance this year. Dave Hipperson has compiled the usual list of records received so far. If you have any outstanding migrant records, do please send them in as an additional list will be included in the newsletter next spring. One of the more exciting migrants that did turn up was a new county record in the form of the pyrale Sclerocona acutellus, the so-called Thatch Pearl. Of interest among the more common migrants was that many recorders reported a high proportion of the dark form of Plutella xylostella Diamond-backed Moth towards the end of October. As well as the example above, it is encouraging that during such a difficult season, no fewer than seven new species have been added to the Norfolk list.

Norfolk Migrants 2012 Dave Hipperson page 10 Further encouragement has come in Norfolk Moths Website details page 12 the form of a CPRE award for the Advertisement page 13 Norfolk Moths website. It was Photographs page 13 commended for its innovative and Norfolk Moth Survey Newsletter 82 Page 1 of 14 ground-breaking format, incorporating the gathering and disseminating of records and information about the moths of the county. It was also noted that other moth groups had begun to follow Norfolk’s lead in such ventures. Our congratulations go to Jim for all his hard work in setting up and maintaining the site for the benefit of us all. Less welcome has been the news regarding ash dieback caused by the fungal infection Chalara fraxinea. With Norfolk and Suffolk appearing to bear the brunt of things so far, it could have far-reaching implications for our ash-feeding moth species – and indeed many other reliant creatures. While only time will tell, the potential effect of this and the various other imported tree diseases on our native wildlife in the future is quite worrying. Our guest speaker for our spring indoor meeting next year will be Les Hill from Butterfly Conservation. The meeting will take place on Wednesday 13th March at 7.30 pm in the Orchard Room at Mangreen Hall, TG215030. In order to cover our costs, we do have to make a small charge of £3 for this meeting, but that does include a cup of tea or coffee and a piece of cake. To conclude, a big thank you as always to all our recorders and supporters. Without you, NMS would not exist.

Please keep sending in your records and photos! This table shows the quantity of records in the Norfolk moth database from year 2000. While showing the general increase in moth recorders over the 12 year period, it also gives a rough indication of the “good” years for moths (2003, 2006 and 2009). Not all the 2012 records Norfolk Moth Survey Newsletter 82 Page 3 of 14 have been received, however I don’t think it is going to be a classic year! I would also like to take this opportunity to appeal to the small minority of recorders who send records to me on paper / cards / notes. If I can persuade you to try the electronic methods, it would be much appreciated. The on-line Recorder, including a new virtual version of the old NMS record card, can be found on the website:- www.norfolkmoths.co.uk Jim Wheeler County Moth Recorder. BRETTENHAM HEATH - JUNE 16TH As the car rocked with each passing gust of wind, we gripped our warming cups of coffee more tightly. Heavy grey clouds scudded across the darkening sky and the air felt chill and dank. Was this November? No, it was Brettenham Heath in mid-June! In what was to become a familiar routine for this season, Joan and I had set off for this field meeting more with a sense of resignation than hope. On arrival at Brettenham, I had even got out of the car and walked for some distance along the track, net in hand, hoping to disturb some stunning rare Breckland micro from the fine grassy sward. Right. As we huddled back in the car, sipping our coffee, our spirits were raised by the spotting of a couple of Stone Curlews flying in at dusk. But that was about it.
