Deckman, for awhile every necrotizing spider bite in the Pacific Northwest was deemed to be that of the Brown Recluse, but in fact, it is the Hobo Spider, that we now have here, that is causing the problem. Of course, when it comes down to it, what's in a name, they both pack a hell of a wallop. My cousin's wife was bitten on the face by one and it caused some serious problems for her.
