Male Black Widow Spiders

On average, male black widow spiders are smaller than females, reaching only about half their size in length. However, the legs of the male black widow are considerably longer in proportion to the female’s and are marked by orange and brown at the joints. Males may exhibit red and white stripes on the abdomen depending on the species and are more colorful and finely patterned than females.

A mature male black widow spider sends vibrations to a female to initiate mating. Like females, male black widow spiders are shy and prefer to dwell in dark, dry and isolated locations such as cellars, sheds and basements.
