All spiders have four pairs of legs and two major body regions.
The most commonly encountered spider around the outside of a home and inside garages in the Coachella Valley is the Black Widow Spider, Lactrodectus hesperus. The adult female Black Widow has a rounded, glossy black body. The underside of the abdomen usually contains a marking similar to an hour glass and is orange to red in color. Egg cases are a round, yellowish ball, about the size of a marble. The young spiderlings are much smaller and hatch in the spring and early summer.
