Recluse spiders like to hide in out of the way places that are not often disturbed, but they emerge at night to hunt for prey. It is best to look at the eye pattern recluse spiders have six equal sized eyes arranged in three pairs along the front of the head. The body size differs by gender the female body length is typically 12-16mm (not including legs), while the male’s length is 6-8mm, but with longer legs compared to that of the female.īrown Recluse spiders ( Loxosceles reclusa), are often identified by the violin-shaped marking on their cephalothorax, but other spiders may have similar markings.
The white abdominal stripes can distinguish this species from the black widow, but the white stripes are often difficult to see on darker colored brown widow spiders.
