brown recluse spider
a small, pale-brown, venomous North American spider, Loxosceles reclusa, distinguished by a violin-shaped marking near the head, found outdoors in rock niches or indoors in drawers or dark corners: its bite may cause deep skin ulcers that are occasionally fatal.

Venomous species (Loxosceles reclusa) of brown spider, most common in the western and southern U.S. The brown recluse is light-coloured, generally with a dark violin-shaped design on its back, for which it is sometimes called the violin spider.

About 0.25 in. (7 mm) long, it has a leg span of about 1 in. (2.5 cm). It has extended its range into parts of the northern U.S. and is often found under stones or in dark corners inside buildings. The venom of the brown recluse destroys the walls of blood vessels near the site of the bite, sometimes causing a slow-healing skin ulcer. Bites are occasionally fatal.
