Latrodectus mactans (Fabricius)
Common names.—Black widow, hourglass, or shoe-button spider.
Natural prey.—Cockroaches, Puerto Rico (Petrunkevitch, 1930). U.S.A., Florida, on shipboard (Anonymous, 1939): This is a presumptive host record, as the spiders were not reported as having been seen eating cockroaches; however, heavy infestations of both were found together.
Family LYCOSIDAE
