Daudebardia rufa

Been itching to get out with the Glamorgan Fungus Group ever since it was reformed back in April 2014. Not only for the fungi but a chance to find new sites for Malacolimax tenellus and anything else that came my way. Work and other commitments had always got in the way until a meet at Caerphilly on 31/10/15.

The well attended group gathered in the car park just off Van road; from here we headed off south over into Wern Ddu. Almost immediately on entering the wood I spotted a small clump of Hypholoma fasciculare (Sulphur Tuft) growing off some moss covered logs, the logs looked to have been lying there for sometime. I went over to investigate further to make sure of my identification and to see what else was to be found. While here I decided to peel back a small section of moss from the top of one of these logs and was immediately presented by a small bluish slug. It wasn’t until I picked it up that I noticed it had a small shell on its rear, yes I thought, finally found a shelled slug. On closer inspection I noticed that the shell was coiled and not finger-nail like, it didn’t look like anything I’ve noted as being found in Britain before. The realisation of me finding something new to Britain was slowly sinking in but didn’t want to broadcast it to the group, as I first wanted to make sure. Another member of the group Martin Bell came over and examined the find, he too didn’t recognise it. So I quickly managed some photos and placed it in a pot.

When I got home I immediately trawled through various on line resources and quickly came across Daudebardia. Checking through AnimalBase I saw that they have 14 species listed for that Genus and D. rufa looking to be the most common. Getting all excited I sent an email with attached photos to Ben Rowson to ask for his expert opinion. I also posted an enquiry on Pan Species Listing Facebook group, to which Malcolm Storey agreed that I was on the right track with Daudebardia.

Me, Ben Rowson and Karen Wilkinson have been back on several occasions to search for more, with great success. It can be readily found in the immediate area of first find, getting slightly more elusive further out. Ben has confirmed it as Daudebardia rufa...more about it in the Journal of Conchology pages 119-121 publish on Friday 5th February 2016.

Brown Field Site

One of the best brown field sites found locally to me has to be the area in between Aberbargoed, Bedwellty and Markham, its apparently owned by the Environmental Health section of Caerphilly Council, which department is anyone guess because they don't even now themselves.

I've got some interesting memories of visiting this place over the years. One from back when it was a water filled quarry, where i nearly drowned when i was about 6 years of age. Me and a friend where trying to catch newts that where surfacing near the waters edge. The banking collapsed from underneath me, the rubble trapping me under water. Thanks to Brett Price for the life saving rescue...pulled me out by my basin cut.

Later on it became a landfill site. Me and a few other mates would go scrounging through the rubbish looking for pen knives, the sort you could buy from the local papershop at the time. You had to be quick as there was competition, mostly in the form of the late Rolly Adams.

Markham/Aberbargoed Old Quarry Site
Its now regenerated into an interesting habitat that's become home for a wide range of local flora and fauna...a large area of grassland, surrounded by Gorse, Bramble and Tree. These scrub areas can be almost impossible to get through, offering excellent shelter for the local fox and rabbit population. A matter of a fact, this is probably the only place you can get to see rabbit regularly these day, rabbit has become quite scarce around here.
The wetter grassed areas can amass an interesting display of Southern Marsh and Common Spotted Orchids, many of which take on some interesting forms.

This particular wet area (shown in photo below) has to be my favourite part of the site. I once counted 52 Bee Orchids in this small area, shame its in the process of being taken over by Willow.
Its one of those places you need to keep an eye on where your placing your feet, nearly trod on these little chaps on one of my visits.
Where there are voles there will certainly be vole runs and tunnels. These are always worth a search through. I've found a good number of beetles this way and at this particular site good numbers of the woodlouse Armadillidium nasatum.

Ambulance station field

Tidy weather for a change, my chickens sunning themselves down the bottom of the garden, even had a bit of tunnage from a couple of Dunnocks and a Song Thrush. So its out for a quick nose about behind the old Ambulance Station in Aberbargoed. Its mostly a small area of grassland and planted trees, the northern end of what used to be Bargoed pit. It has one of those stupid outdoor gyms that nobody use.

I mostly focused my search under the moss covered stones found in amongst the trees. Found a number of Glomeris marginata rolled up under most of the stones i turned. This one caught my eye, not seen one this colour. I've seen close, they have always had some black on them and have all been small specimens, this one was large.

Glomeris marginata

Nice to find some Haplophthalmus mengii, collected three, lucky one was a male. I've also taken H. danicus, not to far from here, would very much like to find H. montivagus to round these off. Not the best photo...

Haplophthalmus mengii

I found my only beetle, this i thought would stand nicely for a few shots. Manged to get in one before it tried to make a run for it down a mouse hole. 

Leistus ferrugineus

The walk back took me on to the old train station. A quick search over the walls never fail to produce Clausilia bidentata.

Juv Clausilia bidentata

Clausilia bidentata
Always worth keeping your eyes peeled for the terrestrial Nemertine - Argonemertes dendyi. Found two of a colour i don't normally find, some shade of pink seems to be the usual here. Geonemertes dendyi also seems to be another name for this Australian introduction.

Centipedes

Once again the weather is pwp, checked the forecast with Alfy Taff The Morning Local Weather Butt via Facebook (check at your own risk). More rain on the way by the looks of things lol, not much chance of looking about again.

Lithobius forficatus
Means I'm stuck in, i've decided to mull over some of my Centipede records on Mapmate. Seems I've picked up 22 spp since i've taken an interest in them. Would very much like to focus more on these this year, mostly going over some old ground and try and fill in some gaps...perhaps a lifer or two. Below is my list so far, in some sort of order to how common i seem to come across them.
Lithobius variegatus










Henia brevis was the first Centipede i came across that i weren't sure of, so this went off to Tony Barber who kindly identified it as such. This one was found behind the Rangers office at Llandegfedd Res, not found one since. 

Lithobius macilentus also seen at Llandegfedd Reservoir and in the rubble of whats left of Aberbargoed train station. Would like to pick up on a few more of these, apparently all British specimens appear to be female.

I found L. borealis dead in a spider web in my green house, not sure how it got here, yet to find it anywhere else. The Graig opposite looks suitable so i'm assuming it may have come from here, where i search regularly?

L. curtipes, I've only found at Cantref Res, fairly easy to find here.

L. tricuspis seems to be high up the list, I actually only come across it in the Darren Valley. Found to be common in the two large conifer plantations and surrounding deciduous old woods as you drive up the valley from Bargoed. My first specimens of these where sent off to Tony for checking. I quickly got a reply congratulating me on my find, seem this was to be the second site for Wales.

Lithobius tricuspis
The rest seem to be readily come by, in the right habitat...to some extent. Its always worth checking over what you "think" is a recognisable species in the field. I've been caught out many a time with these. Those small Centipedes you think may be young of one of those larger types, often turn out to be something else. Thought i had something new recently, it turned out to be an odd Strigamia crassipes with 47 leg pairs. Don't want to say to much or put up any photos as i believe Tony is going to write a small note in the next BMIG newsletter.

Strigamia acuminata
Lithobius melanops
Geophilus insculptus

Standing dead Birch


I came across a nice standing dead Birch to scrounge over yesterday. Its situated on a NW facing bank above the Rhymney river, just over from my house. I grabbed a few small handfuls of the looser material to check an was presently surprised at what was contained within this small mix of bark and pulp. Several Craspedosoma rawlinsii, Chordeuma proximum, Platybunus triangularis,and Sabacon viscayanum ramblaianum.

Also had singles of Tachyporus dispar, Megabunus diadema, Rhagium mordax, Anthocoris nemorum and Lepthyphantes minutus. Did also get a few Springtails which i did not bother with, a female Quedius mesomelinus/maurus and some other tiny Staphs I've yet to id.

Old photo of my first Rhagium mordax.
Was not the best day for taking photos, dark and gloomy so the majority of the photos i took were useless.
Tachyporus dispar
Edit...Those Craspedosoma rawlinsii i mentioned above were in fact a new species for Britain. You can read about them and their discovery here Ceratosphys amoena form confusa .I have yet to find C. rawlinsii...

White slugs

Came across an interesting article earlier on the Conchological Society of Great Britain and Ireland website...The White Slug of Storr.

I found slugs to be a tricky bunch to get on with, it was not until Ben Rowson gave me a lesson on dissecting that i slowly became familiar with them. I've also now learnt to appreciate them more and even tolerate them as a Gardener. They've become a group i regularly look out for and I'd really like to find one of those white ones. Don't get me wrong, I've found white slugs, but want to find one from a species that's not usually that colour, like the one in the above link or a nice big Limax spp.

Here are some of those slugs that are usually found some shade of white in my area. Perhaps the most well known for Wales in recent history is the "newly" discovered Selenochlamys ysbryda - Ghost slug. I find these regularly at two sites local to me, one in Bargoed and the other under Hengoed Viaduct.

Ghost slug from behind the fuel station Bargoed


Another introduced species Boettgerilla pallens - Worm Slug. Its becoming a common slug, I've found it at a good number of sites locally.

The more familiar, especially to the gardener, is Deroceras reticulatum - Field Slug. These can be fairly variable in colour and pattern, I've seen whiter D. reticulatum than this but not got any photos of one. Another similar here is D. agreste, these are mostly a northern slug, don't think there are any confirmed sightings for Wales.

Field slug

Arion intermedius - Hedgehog Slug, another commonly found slug but can be easily overlooked.

Hedgehog slug

Would also like to find more pink slugs, like this baby slug here...possible Deroceras reticulatum?


Tiny pink slug.

The Earwig

I've manged three species of Earwig to date, all of which have been found in Wales...i rarely record anywhere else. The most common has to be, Forficula auricularia (Common earwig), find these almost everywhere i look, its a good one to get familiar with.

Been fortunate to find Forficula lesnei (Lesne's Earwig) a few times, these where all confined to the grounds of Llandegfedd res.

The other and I'm surprised I've only found one, that being recently, Labia minor (Lesser Earwig). Took this in my garden under a plant pot. All attempts at getting a good photo of it in situ failed. When i moved it to more favorable location, it instantly flew off...so no photo...UPDATED, i tell a lie, i do have this poor quality photo of it, now attached.

Male Lesne's found near the Rangers office Llandegfedd Res...no "lobes".

Lesser Earwig

For some good online info on these three, with a good photo of them side by side for comparison. Have a look at, The Earwig species of Devon and Cornwall by Malcolm Lee. Its in a link at bottom of this post as a (DOC)

I'm by no means an expert on Earwigs, far from it. I do look for them regularly in my area and think i've become familiar enough to id them all in the field. Well, adults at least, not sure how confident i would be with juv's?

Here I've attempted/provided a quick key to (adults of) five of the Earwigs that's found in the UK, either I've seen myself or know of recent sightings via iSpot and WAB, leaving out Giant and Bone-house Earwig. Both scientific and common names have links to different info or photos. I'm not best at this sort of thing, so if you see it as a fail then please do enlighten me.
