What is the background to this spider, where did it come from, where was it found? This is not the forum for non-British spiders.

Keswick spider photo
Unidentified record CBDC Copyright: David Blackledge Unidentified photo CBDC Copyright: David Blackledge Hi All These photos were submitted to me this week, sent in to the local records centre who came up with a blank. At a first cursory glance I thought an Amaurobidae of some description, possibly a Coelotes until I looked properly at the photo and realised it is next to a 2p coin! A 2p is over 25mm making this beast around 30mm - so presumably a non native import from somewhere, though details of the find were not given. Any suggestions of what this might be? Regards Dave

This is a juvenile Philodromus 'running crab spider' in the aureolus group. These are not identificable to species without microscopical examination of adults, and even then can cause great difficulties even with experienced arachnologists. Yours is probably likely to be the very variable P. cespitum.

Moth trap spider 2
Moth trap spider 2 Copyright: Kate Colles Moth trap spider preserved Copyright: Kate Colles Moth trap spider abdomen Copyright: Kate Colles This spider appeared in our garden moth trap on 25th April 2020. It is only about 4mm long. I think it is from the family Thomisidae by the eyes. Is it identifiable?

Raft spiders occur on extensive heathland with wet acid bog areas or wet fens, and there is virtually zero chance of any entering a house, even if you lived in e.g. the Dorset or New Forest heathland areas. The related nursery web spider, which can occur in gardens, is completely harmless and not known to be able to pierce human skin.

Thank you so much for your time in answering my questions. Both times this week the bites have been 2 pin pricks together but I do see your point about the distance between the the 2 marks, but on neither occasion did it wake me.  I also appreciate your point about the last time this happened (exactly three years ago) and yes it certainly is more than likely that it was coincidence that I then found a spider, and yet....  Also I’m pretty sure the last one was a raft spider by its markings, or is it unlikely for it to enter the house to breed? The photos I was referring to were shown as part of an extreme first aid course by medics, but did relate to other countries

The two red marks are too far apart to be from any British spider. If the two marks on your finger are from the couple of times this week you were woken up, then again they can't be spider bites - each one would leave two pinpricks close together. What makes you assume it must be a spider? A biting insect is vastly more likely.  Spiders of a number of species commonly occur inside houses and in gardens even if you don't see them, so just because you found a large spider (probably one of the larger house spider species) 3 years ago does not mean at all that this spider was responsible for a bite - you just happened to see the spider then. Few spiders have fangs that can penetrate the human skin or have any inclination to try.

PS, most photographs on the internet and virtually all photos in the media purporting to be of spider bites or the results of spider bites are nothing of the sort and nothing at all to do with an spider.

Hi Peter, thank you for your comment.  What makes you think this isn’t a spider bite? I will be so happy if it’s not. A few days ago I woke up with the same thing on my foot. The reason I thought it could be is that the last time this happened (3 years ago) we did indeed find a large spider. Part of my work involves being in very remote places in the world for a reasonable amount of time, before each expedition I have to do a refresher ‘extreme first aid course’ part of which covers spider bites. A colleague came close to losing his arm and spent six months in hospital after our return from one trip, so I have paid close attention and the marks look like the photos I’ve been shown. Obviously I know if these are spider bites I won’t come to any harm from them. Do you know if there is anything I can do to increase my chance of finding this creature if indeed it is living in my bedroom?

These do not appear to be a spider bite.

Raft spider bite?
Spider bite Copyright: Julia Brace I have woken up a couple of times this week with what I think are spider bites. Three years ago at this time of year the same thing happened and we eventually found a huge spider sitting on some cushions but lost it again. Later on that day I saw it down the toilet it appeared to be walking on the water. At the time when I looked it up I thought it was a raft spider. I haven’t found a spider this time yet, the bites don’t hurt or itch and I don’t feel it at the time. Has anyone any ideas or opinions to what it might be. We have a well in our garden and an underground spring. I’m intrigued, but also not terribly happy with the thought of being trampled over in the night by it.

Yes, a clubionid spider, and most likely Clubiona reclusa in a garden. It is probably not mature this early in the season and from its general appearance, but if it was mature then a definite female epigyne structure would be visible on the underneath of the abdomen. This enables identification to species level, but its appearance in air would be very different to its appearance in figures in publications due to refractive indices differences between air and the alcohol from which these figures are always drawn.

Moth trap spider
Moth trap spider Copyright: Kate Colles Spider 7mm front to back. The photo was taken with a microscope in a quiet moment. I also have a picture of the underneath in a not so quiet moment but haven't quite figured out how to use the web site yet. This is my first post. The spider appeared in our moth trap on 11th April 2020. The location is Upper Boddington, Northants. I would like to know if it is Clubionidae and if it is mature. Many thanks, Kate Colles

It will be a Eratigena / Tegenaria (house spider) species, but you will not be able to identify to species without an adult under a microscope.

Help with spider identification

Could anyone kindly offer any suggestions regarding what this large spider is?

Unknown large spider Copyright: Richard Tanner Unknown large spider 2 Copyright: Richard Tanner

The spider was found whilst demolishing an old shed in my garden in West Oxfordshire last week.

I suspect it is a hobo spider (Eratigena agrestis) however I am unsure due to the incredible coloration of the opisthosoma. Apologies for the poor quality of the images, the spider was fast moving and did not like the camera getting close for a macro.

The wooden plank it is sitting on is around 5 inches wide.

Many thanks for your time,

Richard Tanner
