Size
10-20 mm
Identification
A few genera can be identified by distinctive abdomen shape:
First two abdominal segments forming a tapered petiole linking abdomen and thorax: Eumenes, Zethus, Minixi, and Zeta.
Abdomen blunt where it meets thorax, with no obvious petiole between the two. Large, common wasps, with bold pattern: Monobia
Habitat
All habitats from northern boreal forests to the deserts of the southwest
Season
Throughout the warm season, year-round in some southern states
Food
Eumenines prey mainly upon moth larvae, although some take larvae of leaf-feeding beetles. Adults take nectar.
Life Cycle
Most species nest in pre-existing cavities (e.g., old borings in wood, hollow stems, crevices in rocks). They are called mason wasps because they use mud (or less commonly sand) as partitions between their brood cells. Some species construct nests in the ground (e.g., all Pterocheilus, Odynerus, Euodynerus annulatus, E. auranus, E. crypticus). Some ground-nesting species build small mud turrets over the nest entrance (Odynerus dilectus, Euodynerus annulatus). Other species construct more or less free-standing nests of mud ("potter wasps" because of the shape of some of these nests), e.g. Eumenes and Zeta.
Remarks
There are a number of cleptoparasites and parasites of eumenine wasps, with chrysidid wasps, mutillid wasps, and sarcophagid flies being most frequently reared from nests.
