I woke up this morning with a spider in my hair. It was about the size of a 50 p. It looked like a cardinal spider (the shape) but it had a really bright blue body and a yellow/gold head.
Unfortunately I didn't think about taking a picture as I was coming to terms with the fact it was in my hair. I've never seen a spider that beautiful in color and that worries me. I have had a look on the Internet but can't find any that are even close so was wondering if it rang any bells as to what it could be. From the UK.
Outside United States spider identification
If this was indeed a spider, I would really need a picture of it to determine what it might be. I am not an expert of spiders from the UK, but I am also not familiar with any spiders with a bright blue body and yellow head. I had to look up the dimensions of a 50p (27.3mm) to get an estimate of size, which I assume was its leg span. which would make this a medium sized spider. And all the spiders that resemble the cardinal spider in shape, are going to be brown or dull colored. So, I too searched the web for photos and the only one I could come up with that might be close is the orchard spider, Leucage venusta in the family Tetragnathidae. I have attached some pictures below of it. It is quite variable in color, but some color forms of this species have blue legs, a blue underside to the abdomen and a yellowish carapace. The upperside of the abdomen is usually distinctly marked in white, yellow, and black, but at least in one of the photos it is bright blue. However, as far as I can tell, this species only occurs in North America, and I could find no indication of a similar species that might occur in the UK, although some species in the is genus do occur in other parts of the world. So if you think it looked something like the spider in these webpages, then maybe we have narrowed it down a bit. If it doesn't look like it, then I am at a loss as to what it might be. Regardless, you may have to contact a spider expert somewhere in the UK to determine what your spider might have been.
