Diagnostic Notes

Adult wasps are 10-44mm long with a cylindrical body. Adults have a spear-shaped plate (cornus) at the tail end. The antennae are entirely black.

 

Females have a metallic blue head and body with orange legs. A spike-like projection on the tail end of the abdomen protects a female's ovipositor when it is not being used for egg-laying.

 

Males have a metallic blue head and thorax. The abdomen is orange at the centre with black at the base and tail end. The hind legs are thickened and black.
