CHESHIRE (VICE COUNTY 58) SUMMARY OF CHESHIRE MOTHS: 2008-2013 Authors: Steve H. Hind and Steve Holmes Date: December 2015 Summary of Cheshire Moths 2008-2013 Introduction With the absence of an annual moth report for six years and following publication of the 2014 report earlier this year, we have attempted to bring together some of the main changes to the counties moth populations since the last county report for 2007. Individual Micro-moth reports were published for 2008 and 2009 in the Journal of the Lancashire & Cheshire Entomological Society, Volumes 133 & 134, for Sessions 2009 & 2010 of the Annual Report & Proceedings but this is the first report to include the counties macro-moths for those years. Unfortunately, the amount of work required to produce a similar type of document to the 2014 report would have taken well over a year or more to complete and as such a more selective approach has been taken; this translates to producing an account for just those species that have either: been reported on very few occasions, or have undergone significant changes, either in terms of distribution or population Summary No fewer than seven new macro-moth and 23 micro-moth species appeared for the first time in Cheshire during the period covered by this publication; an astonishing number brought about by Moth recording continuing to increase during the period, especially of micro-moths. We received a record 8,200 records of micro-moths in 2008, yet this more than doubled to 17,700 in 2013. There are a number of references, particularly within the accounts relating to macro-moths, where mention is made of either: the nth Cheshire record, or only ‘n’ records this century, or only ‘n’ Cheshire records To clarify these comments, they all relate to known, submitted, validated records within the County database. We are well aware that there are numbers of records (probably thousands or even tens of thousands) which are sitting around on observers’ PCs or in hand-written notebooks, card-indexes, Museum collections and what have you. These potentially include further records of species within the pages of this report. Accordingly, if anyone reader knowns a statement in this respect to be wrong, as they have additional data, please submit it! We are always more than happy to accept additional records irrespective of when they relate to, now or in the past. Reports such as these are only as good as the information they draw on. Throughout what follows, header information relating to each species looks like this: 70.063 Galium Carpet Epirrhoe galiata ([Denis & Schiffermüller], 1775) (1740) Which, reading left to right details: Incoming Agassiz, Beavan & Heckford species number Species’ vernacular name Species’ taxonomic name Species’ Author(s) and year Outgoing Bradley and Fletcher number Page 2 of 47 Summary of Cheshire Moths 2008-2013 3.003 Map-winged Swift Hepialus fusconebulosa (de Geer, 1778) (18) Twenty-four records, all originating from 2009-2010 and half from sites in Alsager and Higher Poynton (MD, SHH). Essentially an eastern species though one of three records from Delamere Forest on 15th June 2010 accounted for 30 adults (MBe, HD, HJ, SHH, GL). 3.004 Gold Swift Hepialus hecta (Linnaeus, 1758) (16) With just eight records coming from the six years under review this species is clearly very rarely looked for within the County – it’s more likely to be found at dusk around bracken than in a trap in the morning. No site produced more than one record and no record produced more than two individuals. Unrecorded in 2010 and 2013, three records in 2011 was the peak. (SHH, LB, BTS, ES and HL). Steve Hind 4.006 Stigmella sakhalinella Puplesis, 1984 (113) This species was first recorded in the county at Moreton cum Alcumlow in 2002, followed by mines at Knutsford, 2004; Sandbach, 2007 and Crewe, 2008. It suddenly became a lot more common in 2010 with records from 10 sites across the county, followed by a further 15 sites in the next three years. Now recorded from 19 hectads across Cheshire 4.019 Stigmella viscerella (Stainton, 1853) (95) A colony of some forty leaf mines was found near Chester Zoo on 6th September 2010, SHH. Tenanted mines were still to be found on 13th September 2010, RW. The only previous record was from Bowdon, prior to publication of the Ellis List in 1887. Steve Hind 4.020 Stigmella paradoxa (Frey, 1858) (82) Prior to 2005, larval mines had been found in ten monads. A further two have now been added, Oultonlowe on 5th September 2012 and Bradwell on 7th October 2013, SHH. Page 3 of 47 Summary of Cheshire Moths 2008-2013 4.022 Stigmella regiella (Herrich-Schäffer, 1855) (107) A single vacated mine at Higher Poynton on 16th August 2010, SHH. There are only two previous records, Bowdon prior to 1887 and Woodley in 1991. 4.024 Stigmella magdalenae (Klimesch, 1950) (104) After finding a large colony in a plantation on the Staffordshire moorlands in 2009, SHH started looking more closely at upland Rowan Sorbus aucuparia nearer to home during the following few weeks and found small numbers of vacated mines at the Moorside Hotel, Higher Disley; Errwood Hall, Goyt Valley and in Hase Bank Wood, Lyme Park, as well as at Brereton Heath in the lowlands. Further mines were found at Sweet Hill, Lyme Handley; Danes Moss and Threeper’s Drumble, Bridgemere in 2010, Rudheath Woods in 2011 and Radbroke Hall Peover Superior in 2013.There are only three previous county records 4.040 Stigmella assimilella (Zeller, 1848) (74) Leaf mines were found on Aspen Populus tremula at Ellesmere Port on 4th October 2011, MBe, HJ. Our only previous record was of mines on White Poplar Populus alba at nearby Rivacre Country Park in 2001. 4.044 Stigmella continuella (Stainton, 1856) (64) Prior to 2010 larval mines of this local species had been found only at Lindow Common (1999), Wigg Island (2003) and Carrington Moss (2001). Between 2010-2013, mines were also found at, Abbots Moss, Cuddington, Delamere Forest, Little Budworth Common, Rudheath Woods, Saltersley Moss, Shemmy Moss, Thurstaston Common and Wybunbury Moss. MBe, HD, RH, SHH, HJ, BS and ES. 4.051 Stigmella poterii (Stainton, 1857) f. serella Stainton, 1866 (59) ** The first Cheshire record. A single vacated leaf mine on Tormentil Potentilla erecta amongst grazed Bilberry Vaccinium myrtillus on the north facing slopes of Knott, Lyme Park on 23rd October 2009, SHH. Steve Hind 4.062 Stigmella samiatella (Zeller, 1839) (88) ** The first Cheshire records. A male to light at Alsager on 13th June 2009, was followed by a female on 25th May 2012 and a male on 3rd June 2012, MD. Discovery of the first capture encouraged SHH to Page 4 of 47 Summary of Cheshire Moths 2008-2013 examine a few mined leaves of Sweet Chestnut Castanea sativa, collected over the years. Amongst these were three samiatella mines from Mottram St. Andrew on 26th September 2004, Aston on 15th October 2005 and Lower Withington on 18th October 2006. Mined leaves were found at seven sites during autumn 2009, followed by a further 28 during 2010-2013. BB, MBe, SHH, HJ, SJM and BTS. The map, which includes the 2014 data, shows that there is now a fairly widespread distribution across the county, with records from 35 tetrads in 17 hectads. 0088 Stigmella samiatella Records max of 2 in week 22 1 Records for Year 2000 onwards [2km] Records for Years before 2000 [2km] SD SE 9 8 55 Records 9 Individuals 7 41 Sites 6 Records max of 2 in week 22 5 First Recorded in 2004 Last Recorded in 2014 4 Records for Year 2000 onwards [2km] Earliest: 05-25 (May-25, 2012) Records for Years before 2000 [2km] Latest: 09-02 (Sep-02, 2014) 3 Jan Feb Mar Apr May Jun Jly Aug Sep Oct Nov Dec Jan Feb Mar Apr May Jun Jly Aug Sep Oct Nov Dec SJ 1 2 3 4 5 6 7 8 9 SK 1 2 4.074 Ectoedemia sericopeza (Zeller, 1839) (21) ** The first Cheshire records. A couple of winged seeds off Norway Maple Acer platanoides with the characteristic mines running from the wing into the seed were picked up in Stamford Park, Hale on 9th July 2011, RHo. Further mines were found along Old Park Road, Stowford, opposite Lees Wood on 4th September 2011, SHH. 4.075 Ectoedemia louisella (Sircom, 1849) (22) ** The first Cheshire records. Several mines were found in Field Maple Acer campestre samara at Tarvin Community Woodland on 14th August 2011, from which two adults were bred, MBe, SHH, HJ. Further mines were found near the M6 at Tabley Superior on 23rd September 2012, SHH. 4.091 Ectoedemia heringi (Toll, 1934) (39) Following discovery of tenanted leaf mines at Errwood on 5th November 2012, a dozen more sites were found, in eight hectads, mainly in the eastern hills, during the next two weeks, indicating a widespread distribution in this area of the county, SHH. Further west, mines were found along the Whitegate Way, Marton on 4th November 2013, MBe, SHH, HJ and Timperley on 17th November 2013, SHH. Our only previous record was from Brereton Heath in 1986.
