Explanation of Names
Pachodynerus erynnis (Lepeletier 1841)
Forewing: ♂ ~9 mm, ♀ 10.5–11 mm(1)
P. erynnis is the only red-marked species of its genus in the US (Matthews & Gonzalez 2004). However, the same general colour pattern is shared by various Eumeninae species in Florida (Euodynerus, Parancistrocerus, Stenodynerus). Pachodynerus erynnis can be distinguished easily from these look-alikes by the absence of a red spot behind the eyes:
P. erynnis Euodynerus castigatus Parancistrocerus fulvipes
se US (occasionally strays into so. ON)(1)
Often nests under siding boards of buildings
Adults are nectar feeders and hunt caterpillars as food for larvae
Life Cycle
Solitary. A parent wasp builds mud cells or uses empty cells of other mud-building wasp species, provisioning the nest with caterpillars. One larva per cell.
seen using empty cells built by Zeta argillaceum, a neotropical species recently introduced to Florida. May also re-use nests of other mud daubers or build its own.
probably parasitized by Chrysis angolensis
