nice, i love spiders.
that one alongside the black widow are the two deadliest spiders in North America.
these are found in garages out here.
"Do not attempt to apply home first aid as a sole treatment. The widow spider along with the brown or fiddle-back spider - Loxosceles reclusa - are the two most poisonous spiders found in the United States. The brown reculse spider's bite is necrotizing and the site of the bite is very slow to heal. A complication of the brown spider's bite is DIC. Again, the black widow spider can be recognized by the red hourglass marking on its ventral side of the abdomen. The brown recluse spider is somewhat smaller (the body of the spider and its legs cover the size of a quarter) than the black widow and has a characteristic fiddle or violin marking on its back (dorsal side near the top of the spider). The brown widow spiders are easily differentiated from the brown recluse because the brown widowed spiders have a similar appearance to that of the black widows and, of course, lack the fiddle marking. The brown recluse spiders are very timid, hence the scientific species name - reclusa."
