Host Associations
- Lepidoptera - preyEumenine provision nests with paralyzed caterpillars; specific records for P. tolteca are not documented in available sources
Life Cycle
As with other potter wasps, females construct mud nests, provision them with paralyzed caterpillars, and lay on the prey. Larvae develop on the provided food source.
Behavior
Observed visiting flowering mustards (Brassicaceae) for nectar. Females engage in nest construction and provisioning typical of the Eumeninae.
Ecological Role
Acts as a of caterpillars and may contribute to pollination through nectar feeding on flowers.
