Roly-poly Killer (Woodlouse Hunter), Dysdera crocata Drury,
This smooth bodied spider is perhaps best distinguished by its large fangs which it uses to feed on pillbugs (roly-polies) and other hard-bodied prey. When full grown they are about .5 inch (1/2″) in length. Dysdera have a generally creamy gray body with distinctly reddish legs and cephalothorax. They live in a silk retreat and hunt at night. Their bite can be painful but they are not aggressive and their venom is not known to cause medical problems. – Colorado Insects of Interest Fact Sheet
