These spiders were about a half inch or less from a cluster of three black widow eggs being guarded by the Mama Widow. I have also found Brown Recluse spiders in such close proximity and am curious about that behavior. I originally thought these were Brown recluse spiders, but after getting one of my boys to hold the charcoal bag so that I could photograph realized that they are not. So, I'm curious as to the ID of these spiders, and also about how these spiders co-habitate in such close proximity without being territorial (for lack of a better word).
