Webs and Devil’s Bit Scabious at Seven Sisters in Neath Port Talbot on 11 th Sept. All photos by RGS. Reminder: reports to Frits About are no substitute for actual1 records.

Dear all, As the good weather continues, the summer of 2014 seems possibly to be one to be remembered for making history for Fritillaries in Wales. Temperatures this week have been in the mid-twenties and SWFs still being seen flying in Carms last week, albeit a bit tatty. It contrasts strongly with summer 2012, when we may reasonably have considered whether, and if so how long before, our scarcer butterflies recover. For some the answers started in 2013, with remarkable signs of recovery for Marsh & High Brown Fritillary in particular. We can only try to get habitat secured and managed right, then let weather do the numbers, but without the first, we don’t even get to the second. This year seems mostly to be very good news. Many smaller marsh fritillary sites or indeed metapopulations have had long awaited increases e.g. Seven Sisters and Rhos Tonyrefail, whereas others have shown even further strength than previously - like Gower Commons, Heads of Valleys, Mynydd Mawr, Ystradgynlais, Castlemartin, Puncheston and Blaencleddau. Yet in North Wales, despite record webs at Harlech, there seem to be too many uncertainties about ensuring the right management to be confident of the longer term of the NW part of its Wales distribution. Hopefully, I’ll be proved wrong here! HBFs had another great year in the Vale of Glamorgan. Plans are afoot to try to expand habitat still further, and rise to the challenge of increasing management and even new sites, in a changing and challenging funding climate. As always, contributions are very welcome – but don’t forget to send in your records to county recorders as well. 1. Pearl-bordered Fritillary (0) reports 2. Small Pearl-bordered Fritillary (9) reports Most of the reports are from Gwent, where the local group’s newsletter comes out at the end of each month, so includes June & July, but missed last “Frits About”. Carmarthenshire (VC44) 12 th June: 1 SPBF - on `nice bit of M24 pasture`in Cilycwm SN740396 (Neil Matthew) Monmouthshire (VC35) 1st June: 4 Small Pearl-bordered Fritillary at Blackrock Quarry, Clydach .

(George Tordoff) 9th June: 2 Small Pearl-bordered Fritillary at Cwm , above Marine Colliery site (Martin Anthoney) 9th June: 10 Small Pearl-bordered Fritillary at Garden City, Ebbw Vale (Nadine Morgan) 20 th June: 2 Small Pearl-bordered Fritillary at Aneurin Bevan Stones, Ebbw Vale . (Martin Anthoney & Roger James) 30 th June: 6 Small Pearl-bordered Fritillary at Blaenserchan . (Rupert Perkins) 16th July: A late Small Pearl-bordered Fritillary, flying at Balance Meadows, Varteg .

Marsh Fritillary (67 + 4) reports Late sightings of adults since last Frits About. There were late June sightings of both adults and eggs from Pembs. Added to earlier reports, there’s a feeling that adult numbers had been quite good compared to recent years. Also a singleton photographed at Blaenserchan in Gwent, presumably a stray (from Aberbargoed) as no obvious local habitat. Summary of recent larval web reports – although a few sites revealed larval webs in August, with first half of September reports in from across South Wales , there is much evidence of good to very good numbers, perhaps surprisingly higher than might be expected from adult counts. But then this shows the value of monitoring and/or surveying during web season as a more reliable indicator. Maybe also the relatively benign summer weather with good vegetation growth, has seen higher than usual survival rates of larvae? There are already several reports of 100+ webs from sites in Aberbargoed, Blaencleddau, Castlemartin, Gower, Heads of Valleys, Mynydd Mawr, Puncheston and Ystradgynlais metapopulations, with some of Carms, Ceredigion and North Wales results not yet available. In North Wales , despite highest web count ever at Morfa Harlech , some of the important sites brought to my attention seem to be inflicted with inappropriate management, either actual damage or perceived risk of such happening at any time. This sort of taint to efforts to monitor and protect the NW part of MF range in Wales, can be demoralising for all involved and it is hoped that more robust solutions can be found. Anglesey Cors Erddreiniog (Anglesey) surveillance to be undertaken on 23rd & 24 th Sept. Reminder: reports to Frits About are no substitute for actual3 records.

Brecon Beacons National Park/Heads of Valleys/north RCT RGS had reliable reports of 29 larval webs at a small site near Hirwaun Industrial Estate . As early as 6 th August, there were 5 very small larval webs (2 on DBScabious plants that were transplanted in 2013, and 3 on older plants). At least 9 adult Marsh Frits were seen flying in the area on 6th June . Nick Sharp advises that Blaen Cynon SAC web numbers were 177 (counted on 3rd & 9 th Sept ) this year, all from the Cors Bryn y Gaer fields, but two webs at Woodland Park , 10 webs at one of the satellite smaller sites in BBNP part of SAC, but none two others. Lucy Emery has only just started searches on sites close to Hirwaun, but already one web at Heol-y- graig, 2 webs at another small site (for first time), several at the large private site in SN9207 (where BC manages habitat but main count yet to be carried out – 72 webs found on 24 th Sept , but a repeat count of a small part of a similar site nearby on 23 rd found only 25% of those found originally on 11 th , so real numbers in Sn9207 may be up to 280 webs), 122 webs at Bryncarnau Grasslands SSSI and 361 webs at Dderi Hir . Caernarvonshire Andrew Graham advises: “We did count three webs from the boardwalk at Cors Gyfeleog , the other day. This is a very wet site and even now, with it so dry, it’s too hazardous to venture more than a few steps from the boardwalk. However, there is Succisa visible into the distance on both sides so there could be many webs out there and it may be one of the best sites nowadays. This is one site where we’ll never manage a full web count!” Carmarthenshire MYNYDD MAWR AREA From Carmel Nature Reserve , Malcolm Samuels, a regular volunteer with WTSWW, writes: “On Tuesday (12 th Sept ) we did a Marsh Fritillary larval web search on the site and I found one on a south-facing unimproved grassland slope. It's not rhos pasture but myself and another guy have both seen adults on the site earlier this summer. The grid ref is SN5916.” A group of 9 of us, mostly volunteers, spent the day on 16 th Sept carrying out the annual web count at BC’s Caeau Ffos Fach/Median Farm reserve in Cross Hands, with a total of 262 webs , much more evenly spread between all of the original CFF fields and the Median SSSI fields. On 18 th Sept , a similar but smaller group of us, counted the webs at an agreement site on Black Lion Road, Cross Hands, finding 17 webs , which was up on last year. Amanda Evans carried out a survey at a site in Cross Hands with 3 volunteers on 11 th Sept and found 9 larval webs . “We also found one web at a site in Upper Tumble . Judith (Weatherburn) and I and a group of volunteers surveyed an area of Llyn Llech Owain Country Park on 10 th Sept and didn’t find any, despite having seen adults flying there in the summer. We are going to try again later as Judith thinks they normally survey a bit later in the month”. Elen Hall has been working with Amanda Evans (Caeau Mynydd Mawr Project Officer) to monitor several sites in the area during the flight period and hopefully I can include these in Frits About. Meanwhile, Lizzie Wilberforce tells me that Rhos Cefn Bryn WTSWW reserve near Llannon , has had a relatively good year with 24 larval webs , the highest of several recent years. NW NPT & BRYNAMMAN (AMMAN & GORS VALLEYS) AREA Reminder: reports to Frits About are no substitute for actual4 records. However, county recorders are included in Frits About circulation list and will thus be alerted to look out for actual records in due course. Please therefore follow up in usual way. Most of SE Wales’ MF habitat potential has been systematically assessed over the last 10 years, but this area only received close focus late last year and this year, with 6 new 1km squares found to be occupied as reported in previous Frits About editions.
