The '''brown recluse''' ('''''Loxosceles reclusa''''', [[Sicariidae]], formerly placed in a family "Loxoscelidae") is a [[recluse spider]] with [[Necrosis|necrotic]] venom. Similar to those of other recluse spiders, their bites sometimes require medical attention. The brown recluse is one of two spiders in North America with dangerous venom, the other being the [[Latrodectus|black widow]].

Brown recluse spiders are usually between {{convert|6| and |20|mm}}, but may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray. The [[cephalothorax]] and abdomen are not necessarily the same color. These spiders usually have markings on the [[Dorsum (biology)|dorsal]] side of their [[cephalothorax]], with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames '''fiddleback spider''', '''brown fiddler''', or '''violin spider'''.<ref name=Yp>{{cite web |url=https://www.yikespest.com/ |title=Brown recluse in Newburgh Indiana | access-date=5 Apr 2021 |website=Yikespest |df=dmy-all }}</ref>
