Tegenaria agrestis

    Alt Name
    Hobo Spider

    They usually have a brown cephalothorax with diffuse, indistinct darker brown markings on the legs and abdomen. The underside of the abdomen has a characteristic yellow marking with no spots. The genus Tegenaria has recently been split: Tegenaria spp. have banded legs, Eratigena spp. have plain legs. Beyond this distinction, species can only be identified by examination of the genitals of mature specimens.
