I found this spider yesterday in the washing machine when i opened the door to take my clothes out. Was impressed with it surviving the wash, so set up a home for it in a jam jar for now. Its body is about 10mm long. Im trying to find out what exactly it is and what to feed it, so any help would be really useful.
It looks like Amaurobius similisto me - one of the Lace web spiders that are common around our homes out outbuildings. feeds on just about any invertebrates that get caught up in its meshy web. One of a handful of UK species that are able to give you a surprising bite if you upset it.
