Potter Wasp (Eumeninae, Vespidae) Nest

The name “potter wasp” derives from the shape of the mud nests built by Eumenes species wasps and similar genera.

Eggs are attached to the top inner surface of the cell before the nest is provisioned with food (stung, paralysed caterpillars and beetle larvae) and sealed. The hatched wasp grubs feed on these living prey. This nest was about 10mm round and attached to the underside of a leaf.
