While typically light to medium brown, they range in color from whitish to dark brown or blackish gray.
However, the "violin marking" cannot be used as a reliable way to identify the spider as many unrelated species of spider have similar markings. Recluses are typically about 7–12 mm long. The most common and most famous species in the United States is the brown recluse spider (Loxosceles reclusa). It is found in a large area of the Midwest ...
Loxosceles deserta, commonly known as the desert recluse, is a recluse spider of the family Sicariidae. [1] It is found in Mexico and the United States.

As well as the Chilean recluse spider, the venom of Loxosceles intermedia has a high concentration of the enzyme sphingomyelinase D. [5] responsible for local and systemic effects, and is one of the main species attributed to deaths in South America, since the systemic effects of the bite occur frequently. The symptoms are not immediate, which ...
Among the spiders bearing necrotic venom, the brown recluse is the most commonly encountered by humans. The range of the brown recluse spider extends from southeastern Nebraska to southernmost Ohio and south into Georgia and most of Texas. It can be distinguished by violin shaped markings on its back.
