Brown recluse spider
The Brown Recluse Spider is also known as Loxosceles reclusa and is one of the most dangerous spiders in North America due to its venomous bite.
They are easily recognizable by their violin-shaped marking on the back. This spider is shy and usually hides in dark and undisturbed places like closets or woodpiles. Its bite can cause serious skin necrosis which can lead to painful ulcers and tissue damage that may require medical treatment.
Though rarely fatal, the venom can cause systemic symptoms in some cases. Because bites are often painless initially, many victims don't realize they've been bitten until symptoms develop that makes it a stealthy threat.
