Description
 
 

Metallic bluish-green cuckoo wasp is an invasive, parasitic cuckoo wasp. It was introduced into North America, probably during World War II, probably on ships with nests of mud daubers on their wooden beams. It is now widespread across the continent, but especially around the coasts.

The head, thorax, and abdomen are bright bluish-green with metallic reflections and coarse sculpturing.

The abdomen has of the male has four segments, that of the female has three segments. The exoskeletal plates on the bottom (ventral) side of the abdomen are flattened or concave. On the male, the rim on the last segment of the abdomen has three nothces, four teeth, and a row of ten small pits along the edge. On the female the ovipositor is very long and stinger-like, and protrudes from the tip (apex) of the abdomen.

There are two large compound eyes, one on each side of the head; and three small simple eyes (ocelli) in a triangular pattern at the top of the head between the compound eyes. The antennae are black, short, and thread-like. They have 13 segments.

The wings have reduced venation. The forewing has 5 or fewer closed cells. The hindwing has a distinct lobe at the base and no closed cells.
