|Moulted spider-skin, about 6.5mm long from the jaws to the tip of the abdomen (i.e. not including legs or palps). Note how the jaws are dark as they are the most heavily chitinised part. Also, only one pair of legs points backwards.|
|Close-up of a section of leg. As well as the covering of small hairs, there are a few long, dark bristles. The green bars indicate these and their number and arrangement can be important features for the identification of some spiders.|
|The skin showing that the spider emerged with a split between the eyes (circled) and the base of the chelicerae. The sternum surrounded by leg-bases (coxae) is clearly visible.|
If you want to know more about spider identification in Britain, I've given details of a few books below, and there is a 'UK Spider Identification' facebook group, plus of course the British Arachnological Society.
