Steatoda nobilis.. male?
Hi all, found it today 21/06/20 in the morning on me in my house after it bit me :(. Felt like wasp bite, thanks God i didn't had a bad reaction. I live in Tadley, Hampshire. Looks like i have a few of them in my conservatory but they come out only after sunset. Do not know how this one ended up on me. It didn't move fast on floor, so could take pics for identification.

Preservation of spiders
I've started a reference collection of spiders but I find that the abdomen can swell and haemorrhage within 24 hours of immersion in alcohol. I'm using isopropyl alcohol diluted with distilled water to 55%. Is this common and does anyone have any advice on how to avoid this?

Steatoda grossa-  CH Copyright: Matt Harvey

Hi,

I’m hoping someone can ID a spider I found in my garden on 17/06/20. Post code is SK8 7DL.

Is it a Steatoda grossa? Female?

It was a beautiful specimen! The gold band was incredible!

Hoping my picture has attached to this!

Thanks, Matt

Possible large Marpissa muscosa
Large Marpissa muscosa female 2 Copyright: Jason ArgentLarge Marpissa muscosa female 1 Copyright: Jason Argent Please excuse the awful photos, but I think I found a female Marpissa muscosa on a dry stone wall in South Gloucestershire (grid reference ST681824). She must have been getting on for 20mm in length, by far the the largest Salticid I have ever seen in the UK! Is this size unusual? Is it worth trying to collect a voucher specimen?

Thanks in advance,

Jason Argent

This is Steatoda nobilis, the so-called 'noble false widow', the spider which the media make such an unjustified fuss about. It has been frequent in the southern coastal counties of England for a great many years, and is nowadays frequent and abundant in many areas of southern England and Wales, including the south coast, south-west, south-east, London area and East Anglia, and increasingly much further north. The media frenzy caused by this spider is unwarranted. Steatoda nobilis spiders are unobtrusive, have no interest in attacking humans and would only bite if they were put into a position where they do so as a defensive reaction. They are no greater risk than honey bees and social wasps. There are a number of other 'false widows' in Britain, some which are native or have been in the country for centuries, so there is a lot of misinformation about these spiders.

Your tiny unknown is probably a baby Zygiella (x-notata). Tenuiphantes type are generally body length 2 - 2.5mm as adults. The linyphiidae are generally small spiders body length from minute 1mm - 3mm although some are larger such as Linyphia triangularis mature in the autumn 5-6mm.

Segestria is a massively bigger spider, 13 - 22mm body length.

Thanks Peter. Never thought it would be a money spider as its size was about 2.86mm calculated by measuring its size on a 35mm frame @ 1:1 and doing the maths

Re: Sardinidion blackwalli - county first?
This certainly looks like Sardinidion blackwalli and the first record in the recording scheme for the species, but an absence of records for a VC on the maps does not necessarily mean a record is new to a VC:- it may mean previous records have not been submitted to the recording scheme. The maps in Locket, Millidge & Merrett Vol. III (1974) and quite a few subsequent NCR updates published in the BAS bulletin need to be consulted (as Theridion blackwalli). I will add your record to our database.

Re: poss Segestria senoculata
This is a linyphiid money spider, one of the Tenuiphantes type. These require careful microscopical examination of adults to identify to species.

The photo is far too low resolution to be able to enable identification, although certainly an orb web species

Sardinidion blackwalli - county first?
Very excited to find Sardinidion blackwalli in my house yesterday, 9th June 2020 - SJ198097. This species is new to Montgomeryshire, I believe, in fact new to Powys and third record for the whole of Wales?

tiny unknown
Have been observing this one for a few days to see if it gets any bigger as it is only 1.5 to 2mm judging by the space it occupies in my full 35mm frame and 1:1 macro. No idea what species it is although I suspect it is an orb weaver/missing sector of sorts. I seems to build a new one every so often and sits in the middle waiting for prey.

This is certainly an Araniella orb web spider, but there are 5 variable species found in Britain, which cannot be identified to species without careful examination of adult female epigyne or male palp structure under a microscope. Yours is likely to either Araniella cucurbitina or A. opisthographa.

I think I’ve narrowed it down to Araniella sp?
Car spider 1 Copyright: Jacky Chase Took this image on 8/6/20 in Langholm, Dumfries and Galloway. Estimated body length 2-3mm. I have no experience in spider identification but I believe it may be one of the Araniella species, but would be unable to pin it down further. Maybe someone else could? I’ve posted it, not least as this website’s distribution maps of the various species might suggest this occurrence be at a ‘new’ location depending on species. The car it was on had been stood in Langholm for the last 9-10 weeks except for a brief visit to the moors above Langholm just a day earlier.

Hi all, I'm usually ok at ID but for some reason this one has me stumped! Found on the side of my shed, hiding behind some wood that was propped up against it. Body length around 2-2.5cm. Location: Norwich (NR1), Norfolk. Date: 09/06/2020. I think it might be the same species as Conor's (who posted a picture yesterday evening)? Thanks!

Thanks Peter. Much appreciated

Sun 7th June 2020 18:11 by Peter Harvey
Yes, this looks to be Scotophaeus blackwalli, although there is a second species which has been found several times in the Colchester area, which looks exactly similar until adults are examined under a microscope, and there are another 2 European species as well, so there cannot be any absolute certainty.

This is a clubionid spider, There are a lot of very similar species which need microscopical examination of adults for species identification.

I am afraid it isn't possible to confirm without examination of the sternum, jaw teeth arrangement and preferably adult genitalia. A side view is also not much help for id.

Photo taken on 26/5/20 in Alice Holt Forest, Hampshire, Grid Reference SU 81001 42531.

This seems to be showing one species of spider preying on another.  I think the prey spider may be Metellina segmentata.  I'm not at all sure of the predator, maybe in the genus Philodromus?

I'd be interested in confirming or otherwise the identification of both spiders.
