Please see attachment of spider found in our bedroom tonight. The spider was difficult to capture as it kept jumping, but was eventually caught and released. We're worried it looks similiar to a black widow with large bulb, distinctive marking on bulb, with what appeared to be fangs. Roughly 10mm in length (not including Legs). The markings to the human eye appeared Red, but on the camera shows a brown/orange. (possibly distorted by the flash) Identification would be much appreciated so we can get some sleep tonight!!! Thanks
When you mention that it was difficult to capture because it 'jumped', then it can only be a Salticid, ie a member of the family of jumping spiders. The image does not show the carapace very well and I have not seen abdomen markings like this before. You can forget all about widows and sleep well.
I have to say, I think this spider more closely resembles a steatoda nobilis. This is one of the UK's "false widow" species, it's important to focus on the "false" aspect in the name (nobody thinks they're rich if they find "fool's gold", likewise you're not in danger when you find a "false widow"). They are not dangerous, but like a dozen or so UK species they can deliver a nip, which may not be particularly enjoyable...but they don't kill anybody, or cause any serious illness. They are usually quite docile and no problem if left alone, bites usually only occur if they are trapped in clothing etc.
Compare to this pic...
If they bother you, they are usually quite happy on the outside of houses or around sheds & outbuildings. I stayed in a holiday resort on the Isle of Wight, where every chalet's bathroom had several living in the interior window frames! :-)
