This spider can have a painful bite if you bother it, but is only mildly poisonous. May cause itching and slight swelling. For some more info check out "woodlouse spider" on wikipedia.

Can give one quite a scare, with those garish colors, while turning over leaf litter and earth in the garden! Sensitive to vibration; wants nothing more than to hide, may have poor eyesight in the daytime. If one comes toward you, tap the ground in front of you and watch them scurry away. They prey mainly on pillbugs (armadillidium vulgare), which are also called woodlice.
