My son grabbed his shoes from the top of his closet. There was a mud cocoon inside one, when he knocked it out, it broke apart, and all these spiders were inside near hatching. To me, and I'm no scientist, they look like several different species. There was also a large larvae. Don't know what any of it is. One looks like a wolf spider, one an orchard spider, and one a brown recluse, is that even possible?
