Oxybelini
square-headed wasps
Oxybelini is a tribe of Crabronidae containing approximately 15 genera and over 440 described species, commonly known as square-headed wasps. Members are specialized predators of flies, exhibiting a highly concentrated stinging pattern that targets the prey's nervous system with a single thoracic sting rather than the multiple stings typical of other digger wasps. This reduced stinging sequence correlates with the simplified nervous system of dipteran prey, which typically possess a single fused thoracic ganglionic mass.
