Black widow spiders are common throughout Arizona, although they are seldom seen. They spin "messy" webs in dark and quite places. Only the females pose a danger to humans, since, while its venom is equally toxic, the male's fangs are too small to puncture human skin. If you suspect you have been bitten by a black widow spider, contact your local poison control center.Download 136 KB
Credit: Alicia LafeverSource: Catoctin Mountain ParkThe black widow, Latrodectus mactans, is a highly venomous spider. The female's abdomen is very shiny and black with red markings (if she has the red hourglass-shaped marking, it will be on the underside). They tend to have "messy" webs and love to build them in cracks of rocky outcrops.
