Brown spider

Hi Kelsey, do you have any other images of this spider? I do not believe this is a Brown Recluse. The Brown Recluse usually is found a bit further south than PA. Brown Recluse spiders are "uniformly colored... with no stripes, bands or spines" on the legs. Your spider here has clear banding on the legs. Brown Recluse also have a distinct violin shaped dark marking on the thorax like in this image: http://bugguide.net/node/view/160732 Your spider has no such marking. I think the safest thing to do would to mark this spider as an unknown species. Perhaps someone with a bit more spider knowledge can figure out what type it is.
