Description:This “Black Widow” spider, Latrodectus mactans, was photographed during a study of migrant labor camp disease vectors.
Though spiders are “mostly” harmless to man, two genera, Latrodectus spp., the “Black Widow” spiders, and Loxosceles spp., including the “Brown Recluse” spider, Loxosceles reclusa, produce bites, which are poisonous to humans.
