Known in scientific terms as Loxosceles reclusa, the brown recluse is a very interesting creature.  Its common name refers to both its description and habitual instincts.  The spider is brown with a violin-shaped mark on the back of its cephalothorax region.  These spiders have also been called "fiddleback" or "violin" spiders because of it.  The "recluse" section of the common name refers to the fact that this species prefers to live in seclusion from other organisms.
