Boll's Potter Wasp
Eumenes bollii, commonly known as Boll's Potter Wasp, is a solitary potter wasp in the Vespidae. The is named for its distinctive nest construction: females craft small, urn-shaped mud resembling miniature pottery. These nests are provisioned with paralyzed caterpillars that serve as food for the developing larva. The is part of the diverse Eumeninae , which includes many species with similar mud-nesting .

Behavior
Females construct free-form mud nests in the shape of small urns or pots, complete with fluted necks. Each nest is built entirely before the hunts for prey. The female paralyzes several small caterpillars and stocks them inside the completed pot, then lays a single and seals the top with a mud plug. The paralyzed prey remains fresh for the developing larva, which hatches, feeds, pupates, and eventually chews an exit hole in the side of the pot to emerge as an .
Ecological Role
As a of caterpillars, this may provide of and larvae in its . The mud nests also serve as potential habitat for nest and commensal organisms, though specific associations are poorly documented.
Human Relevance
The mud nests are occasionally encountered on human structures and in gardens. The is not aggressive and poses minimal stinging risk to humans. The nests are sometimes mistaken for unusual debris or fungal growths. Some sources suggest that Native American pottery designs may have been inspired by the form of potter wasp nests, though this connection requires further verification.
Similar Taxa

- Sceliphron caementariumThe black and yellow mud dauber builds multi- mud nests rather than single urn-shaped cells, and provisions with spiders rather than caterpillars
- Trypoxylon politumThe pipe organ mud dauber constructs linear mud tubes rather than rounded urns, and nests are often built cooperatively by male-female pairs

Nest Construction
The mud urn is built in its entirety before provisioning begins, a behavioral sequence distinct from many other solitary that excavate burrows or build nests incrementally. The fluted neck of the nest is a characteristic feature of the Eumenes.
Etymology
