The brown recluse spider is native to the United States from the southern
Midwest south to the Gulf of Mexico .
[2] The native range lies roughly south of a line from southeastern
Nebraska through southern
Iowa,
Illinois, and
Indiana to southwestern
Ohio. In the southern states, it is native from central
Texas to western
Georgia. They are generally not found west of the
Rocky Mountains.
[3] A related species, the
brown violin spider (
Loxosceles rufescens), is found in
Hawaii.
[4] Despite many rumors to the contrary, the brown recluse spider has not established itself in California,
[5] nor Canada
[6]. There are other species of
Loxosceles native to the southwestern part of the United States, including California, that may resemble the brown recluse, but these species have never been documented as medically significant.
