Norfolk Moth Survey c/o Natural History Dept., Castle Museum, Norwich, NR1 3JU Newsletter No.86 November 2014 INTRODUCTION Opinion seems to be divided over whether this has been a good year for moths or not! Certainly there has been much of interest, but that seems to have depended on local conditions – and they have varied considerably across the county and across the season. The mild autumn definitely brought some unusual sightings, with some species, such as Rosy Footman (and, indeed, other Footman species) producing unexpected extra broods in late October and early November. No fewer than ten –or possibly just eight! - new records for Norfolk were added during the year. The majority of these are species that seem to be spreading north with changing climatic conditions. However, two have slightly different background stories – Epinotia cinereana has only recently been given full species status, having been regarded previously as a form of E.nisella. Confusion surrounds the possible nineteenth century records of Endothenia ustulana, but we now have a definitely confirmed specimen in 2014. At least two more of the additions were migrants – Silvery Gem was not only a first for Norfolk, but also only the second for Britain. Meanwhile, a search for rare migrant birds on the north coast resulted in the surprise sighting of the county’s first Crimson Speckled. Some recorders complained of a generally poor year for migrants, CONTENTS: while others deemed it quite exciting, with a good range of species, including Introduction Ken Saul page 1 large numbers of Rusty-dot Pearl Udea CMR’s Report Jim Wheeler page 2 ferrugalis reported in the autumn. As Can I borrow a boat? Jim Wheeler page 4 usual, Dave Hipperson has compiled a list of migrants received so far.

As you can read Crimson Speckled James Lowen page 19 later, a confusion of dates with the locals meant that we visited Bryant’s Norfolk Moths Website details page 20 Heath on two successive weekends. Photographs page 21 This actually proved fortuitous, insofar as the first attempt saw very cold Norfolk Moth Survey Newsletter 86 Page 1 of 22 temperatures and very few moths. Woodland moths were the target for National Moth Night in early July and we paid our first group visit to Gawdy Hall Big Wood. If you trapped elsewhere over that weekend, don’t forget to send in your results. Many thanks to everyone who came along and helped or supported at the various field trips. Thanks are also due to all the authors of the different reports and articles in this newsletter. Without your efforts the newsletter wouldn’t exist. In the light of that, we would again appeal for articles for inclusion, especially for the spring editions when we tend not to have so much news to report. If you would just like to tell us about mothing on your local patch or in your garden, that would be very welcome. While on the subject of the newsletter, it may not be generally realised that monies received for it also help to support the Norfolk Moths website. With increasing numbers of people reading it online, the financing may be something we will need to look at in the future. Please let us know if you have any thoughts or ideas about all this. After giving it a miss earlier this year, we have decided to organise another indoor meeting for next spring. Our good friend Matthew Deans, from the Suffolk Moth Group, has kindly agreed to give us an illustrated talk on Migrant Moths of East Anglia. This will take place on Tuesday 14 April 2015 at 7.30 pm in the Orchard Room at Mangreen Hall, TG215030. Please put the date in your diaries now and come along and join us. In order to cover costs we have to make a charge of £3 for this meeting, but that does include a cup of tea or coffee and a piece of home-made cake. Finally, as always, a big thank you to all of you for your help, support and enthusiasm for continuing to record the moths of Norfolk. Ken Saul COUNTY RECORDER’S REPORT Please find listed below a selection of notable records taken from data that has been sent to me so far this year. The 2014 list includes eight species new for Norfolk (possibly ten), plus two new for Vice-county 28 (West Norfolk) and five new for Vice-county 27 (East Norfolk). The list also includes several species recorded this year that were last listed by C.G. Barrett in Victorian times, plus a couple of extra records from last year (2013). The New for Norfolk and Post Victorian Norfolk records in more detail: Yponomeuta irrorella (Scarce Ermine) - New for Norfolk. A scarce and local species, occurring in southern and south-eastern England. New for Norfolk in 2013 (not identified until Aug 2014) at Cley-next-the-Sea VC27. (I. Walker, 30/07/13) Amphisbatis incongruella (Ling Tubic) – Post Victorian Norfolk. Plain looking small moth, the males flying on sunny days. New modern-day record of a male taken at Dersingham in 2014 (01/04/14 Gen. Det. R. Jones) Scarlet Tiger Callimorpha dominula – Post Victorian Norfolk. A spectacular adult moth was bred from a single caterpillar was found in a ladies lavatory at Martham in 2014, the only modern-day record, of unconfirmed provenance, in Norfolk. (D. Holman, C. Stean 09/04/14) Psychoides verhuella (Hart's-tongue Smut) - New for Norfolk. Several specimens where collected and bred from Phyllitis scolopendrium (Hart's-tongue Fern) in a Heacham garden. (P. Cobb, collected 10/04/14, emerged 13/05/14 – Gen. Det. (Male + Female) J. Wheeler) Adult moths are day-flying and similar to the other fern feeding Psychoid, P. filicivora, but show a violet tinge and lack the white tornal spot. Lampronia luzella (Wood Bright) – Post Victorian Norfolk. Found very locally in woodland throughout Britain, a specimen was netted at Ashwellthorpe VC27 in 2014 (A. Musgrove, 10/05/14) Diplopseustis perieresalis (Eastern Black Tabby) - New for Norfolk. The first record of this species in Britain is from Tresco, Isles of Scilly in 2001. All UK specimens are thought to be either migrants or introduced through accidental importation of plants from Asia.

I have not listed the common migrants such as Silver Y, Dark Sword-grass, Plutella xylostella, & Nomophila noctuella. White-point records are not listed as we are not able to say which records are migrants and not residents. The records are for single adult moths unless given otherwise in the notes column.
