The brown recluse is not plentiful in PA but they are here.I know of two people that were bitten in my area.The one a lady had to have her nose removed.Another is a man I work with who got bit in his pick up on the way to work.He ended up in bed for three weeks with a leg that looked like hamburger.Luckily he healed with out amputation.He still has the scars but he also has his leg.The brown recluse bite can cause death.The spider has a violin shape on it's top front which I think is called the borex or something like that.
