Caption:
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, and Loxosceles, which includes the brown recluse spider, Loxosceles reclusa, inflict bites that are poisonous to humans.
