Wasps in the genus Eumenes can be recognised by the fact that the first abdominal segment is long and slender, very thin at the front and widening towards the back.

It is on the wing from about April to November in North Carolina and is found in glades, rough shrubby areas and forest verges.

[4] Like other members of the genus, the female Eumenes fraternus builds a pitcher-shaped nest in which to lay an egg.

When it is ready, the wasp inserts her abdomen into the hollow interior and lays an egg, suspending it on a fine thread.

When she has placed enough provisions in the pot, the wasp seals the top with damp soil and goes off to build another nest.
