In , Vetter covers topics such as taxonomy, identification, misidentification, life history characteristics and biology, medical aspects of envenomations, medical conditions misdiagnosed as brown recluse bites, other spider species of medical consideration (several of which have been wrongly implicated as threats to human health), and the psychology behind the entrenched reasons why people believe so deeply in the presence of the spider in the face of strong, contradictory information. Vetter also makes recommendations for control of the spider for households in areas where the spiders are found and describes other species of recluse spiders in North America. Although r was written for a general audience, it is also a valuable source of information for arachnologists and medical personnel.
