An Illuminous Coloured Spider UK

Luminous, Illuminous, call it what you like, but wow, take a look at this spider I spotted that was just chilling on the leaf of a Grey Willow tree. Sometimes I'll see an insect that looks really strange, and then find out that it's nothing out of the ordinary to those in the know, and very common in the UK. In this case I am not sure. But this certainly looks very strange. The picture doesn't do it justice. In the flesh it looked much more bright green / yellow in appearance. Almost glowing! If you look at the close up picture it even has a purple back abdomen (Spinnerets).

Bright colours are usually a warning sign on animals and insects, but in many cases they are also just for show, and the animal / insect is harmless. I wouldn't put my money on this spider being harmless though, as many of the fake widows have left some seriously bad injuries on the people they have bitten.

Some victims have been left scarred for life, and some have even had to have body parts amputated. One case that springs to mind is where a woman had to have some fingers removed. This subject is making me itch! Does anyone know what type of spider this is? If so post a comment below.
