Range
The southern widow is primarily found in (and is indigenous to) the southeastern United States, ranging from Florida to New York, and west to Texas, Oklahoma, Arizona, and Nevada The northern black widow (L. variolus) is found primarily in the northeastern United States and southeastern Canada, though its range overlaps with that of L. mactans. In Canada, black widows range in the southern parts of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario. In the Dominican Republic is found along the whole country.
Latrodectus mactans, along with Latrodectus hesperus and Latrodectus geometricus (the "brown widow spider"), is established in the Hawaiian Islands (USA). One pathway of entry into Hawaii for at least one of these black widow species is imported produce (which is also considered an important potential pathway for widow spiders elsewhere).

Famous quotes containing the word range:
“During the cattle drives, Texas cowboy music came into national significance. Its practical purpose is well known—it was used primarily to keep the herds quiet at night, for often a ballad sung loudly and continuously enough might prevent a stampede. However, the cowboy also sang because he liked to sing.... In this music of the range and trail is “the grayness of the prairies, the mournful minor note of a Texas norther, and a rhythm that fits the gait of the cowboy’s pony.””
—Administration in the State of Texa, U.S. public relief program (1935-1943)
“The Canadians of those days, at least, possessed a roving spirit of adventure which carried them further, in exposure to hardship and danger, than ever the New England colonist went, and led them, though not to clear and colonize the wilderness, yet to range over it as coureurs de bois, or runners of the woods, or, as Hontan prefers to call them, coureurs de risques, runners of risks; to say nothing of their enterprising priesthood.”
—Henry David Thoreau (1817–1862)
“As to spelling the very frequent word though with six letters instead of two, it is impossible to discuss it, as it is outside the range of common sanity. In comparison such a monstrosity as phlegm for flem is merely disgusting.”
—George Bernard Shaw (1856–1950)
