This important wasp can be recognized by the fact that the first abdominal segment is long and slender, very thin at the front and widening towards the back. Its coloring is black with a scattering of ivory-colored markings. It is distinguishable from other potter wasps by its dark, evenly-pigmented wings.
Larvae feed on insects like caterpillars hunted by the females. Adults feed on nectar and pollen from flowers.
The female builds a miniature pot out of mud in which it lays an egg and places a live caterpillar for the larvae to feed on when they hatch. When she has placed enough provisions in the pot, the wasp seals the top with damp soil and goes off to build another nest.
