Segestria florentina hiding in sleeve
The spider was actually captured and put in a jam jar so I was able to measure her length, excluding appendages, which came out at bang on the 22mms given in Dick Jones' book, which I have. Surely this means she's an adult?

Location of Segestria florentina
Thanks very much for the information. Segestria florentina is often found in walls or in cracks on the outside of buildings but quite a few records are from indoors. The adult season charts are for adults, and your spider is not necessarily adult (and it is difficult to tell anyway in Segestria except for adult males), so the occurrence of the spider indoors probably can't be read as too significant - the unseasonably warm weather would probably make it more likely to stay outdoors I suppose, rather than move indoors.

Location of Segestria florentina
The segestria was hiding in the sleeve of a Beaver uniform, indoors, at postcode KT3 4DS. The bite happened at 10 am on Tuesday, 24th January 2012. I note from the map that you have no previously recorded incidences of this spider during January - do we attribute this to the inseasonably warm weather?

Is this Segestria florentina?
This certainly looks like Segestria florentina and there is a hint of metallic green on the jaws, typically found in this species of Segestria. Can you provide a postcode or map grid reference, date and the situation in which the spider was found, so that we can add your record to the recording scheme.

Can anyone confirm that the spider that bit my boss was Segestria florentina? Is this Segestria florentina Copyright: Elizabeth Kay

Re: Unidentified jumping spider - Heliophanus sp?
Robert

The species looks like Hasarius adansoni to me.  I've recorded this species in Leeds (Tropical World) and it is a species that is recorded/ observed in hot-houses and other artificial heated environments worldwide.

Steatoda grossa
Thanks Peter.  I've sent my postcode via separate message. 

I've never seen one of these spiders before and to be honest would have preferred not to have had one in my kitchen :)

Kind regards Andrea

Steatoda grossa
Yes, this looks like Steatoda grossa, probably a juvenile (which tend to have the same kind of pattern as adult males). I'd appreciate a postcode or map grid reference so that your record can be added to the recording scheme (contact us). There do not appear to be many records for Pembrokeshire

Is this a steatoda grossa?
Hi, I found this spider when I was cleaning out my kitchen storage cupboard.  I think it may be a false widow spider, steatoda grossa?  I was wondering how common they are in Pembrokeshire?

Certainly not British. Looks to me at least superficially most like an Evarcha species, but it would almost certainly need an actual specimen under a microscope to identify - presumably this could originate from more or less any part of the World. You could try the salticid expert Dmitri Logunov Dmitri.V.LogunovATmanchester.ac.uk (@ replaced by 'AT')

Unidentified jumping spider - Heliophanus sp?
Are these photos of Heliophanus kochii? They seem to match photos of that species on the web but the species appears not to be recorded from Britain. They do not match pictures of the common British Heliophanus species, H. cupreus. All were taken in the glasshouses of the Royal Botanic Garden Edinburgh (NT2475) where our staff say they appear to be very abundant. The individual photographed here was on leaves of begonias.

There don't seem to be many records in Oxfordshire - can you email me your postcode so that we can add the record to the recording scheme?

Thanks. It was found inside my living room in northern Oxfordshire (Charlbury).

Almost certainly a juvenile Salticus scenicus (juveniles variable in scales and pattern). You don't say where you found the spider, but S. cingulatus would only occur in semi natural habitats on tree trunks or old fence palings or similar and would not be confirmable unless adult and examined under a microscope - adults of Salticus species are generally early summer spiders, May/June peak. May be earlier this year if we don't get any hard frosts and snow - some plants have been in flower extraordinarily early.

Salticus ?cingulatus
Dear all

Saw this salticid today. I think it's Salticus cingulatus as it doesn't have the strong abdominal markings of S. scenicus and it resembles this photograph link. What do you think? I attach one of the better photos I got.

Best

Request for Information on B. duffeyi & A. fulvolineata
All

I am undertaking a research project investigating the ecology of two saltmarsh and UK BAP spiders, Baryphyma duffeyi and Arctosa fulvolineata.  If readers could e-mail me (Richard.Wilson_ecology@yahoo.co.uk) with any information based on personal experience of these species or make me aware of grey or scientific literature that deals with their ecology or distribution (UK or European), I would be most grateful. 

Please note however, that I would need this information to be available in sufficient time for me to include it in the report which has a deadline of early February 2012.

Many thanks in anticipation

Richard Wilson (AO for Yorkshire)
