Potter Wasp
Potter wasps construct mud "pots" or nest in underground burrows, cavities in plant stems, or abandoned nests of other wasps.  Adult potter wasps are commonly seen on the ground searching for prey or nectaring at flowers. They are common and can be numerous. I have encountered them thousands of times, and never once have they taken notice of me. I've never heard of anyone being stung by one.

Potter wasps nests can have one or more individual cells. When a cell is completed, the adult wasp collects a beetle larvae, spider or caterpillar and paralyzes it with venom and places it in the cell to serve as fresh, living food for the larva. In a few species, the adult wasp lays a single egg in the opening of the cell, suspended from a thread of dried fluid. When the wasp larva hatches, it drops and immediately feeds upon the larvae, and later breaks out of the nest to begin its adult life. Adult potter wasps feed on plant nectar.

Hymenoptera (Latin for membrane wing) is a vast assemblage of insects second only to Coleoptera (beetles) in the number of described species. Hymenoptera number some 115,000 species – of which 18,000 live in North America. Hymenopterans inhabit a wide variety of habitats, and show an incredible diversity in size, behavior, structure and color.
