The southern widow is primarily found in (and is indigenous to) the southeastern United States, ranging as far north as Ohio and as far west as Texas. [9] The northern black widow (L. variolus) is found primarily in the middle Atlantic states, though its range overlaps with that of L. mactans.

As such, it is a 'cousin' to the more infamous Latrodectus mactans (black widow).
