Back during the summer of 2010 I found a few mud balls attached to some porch furniture. The furniture was going to be cleaned, so I thought I’d save the mud balls to see if anything came out of them. A week later, this Potter Wasp (Eumenes sp.) emerged from one of the mud balls. Presumably the mud ball was full of paralyzed caterpillars, and this wasp spent its larval period eating those caterpillars.
