The brown recluse is a venomous spider most commonly found in midwestern and southern states of the United States. It is about one-half inch overall and has long skinny legs. The brown recluse is brown with a characteristic dark violin-shaped marking on its head. It is most commonly found outside in wood, leaves, or in piles of rocks. If a brown recluse wanders indoors they will go to dark closets, shoes, or attics. The brown recluse is a non-aggressive spider and will only bite when it is disturbed.
