Scientific name: Loxosceles spp.
Facts: Recluse spiders live in undisturbed areas. The body of an adult is 3/10 to 1/2 inch long, but much larger if legs are included. Adults have a violin-shaped spot on the cephalothorax (head and thorax combined). The bite can result in a severe wound that may require two months to heal. Usually, the internal reaction to a bite is less severe than is the reaction to the bite of a black widow spider.
The brown recluse spider, Loxosceles reclusa Gertsch and Mulaik, is the species that is often mentioned. However, there are about six species in Texas and they are difficult to distinguish the species.
