Potter Wasp or Mason Wasp

Description:

This ‘Potter Wasp’ had constructed its nest (pot-shaped structure) in the “back side of the part that was just above the front left tyre of a friend’s car”. That area was hardly visible. There were two pot-shaped structures and it was on the verge of completing the third one.

Notes:

Eumenine wasps are diverse in nest building. The different species may either use existing cavities that they modify in several degrees, or they construct their own either underground or exposed nests. The nest may have one or several individual brood cells. The most widely used building material is mud made of a mixture of soil and regurgitated water, but many species use chewed plant material, instead. The name 'Potter Wasp' derives from the shape of the mud nests built by species of Eumenes and similar genera. When a cell is completed, the adult wasp typically collects beetle larvae, spiders, or caterpillars and, paralyzing them, places them in the cell to serve as food for a single wasp larva. As a normal rule, the adult wasp lays a single egg in the empty cell before provisioning it. Some species lay the egg in the opening of the cell, suspended from a thread of dried fluid. When the wasp larva hatches, it drops and starts to feed upon the supplied prey for a few weeks before pupating. The complete lifecycle may last from a few weeks to more than a year from the egg until the adult emerges. Adult potter wasps feed on floral nectar.
