Short-tailed Ichneumon Wasp
Ophion
Aguila, Maricopa County, Arizona. 26 March 2017.
Ichneumonidae -- Ichneumon Wasp Family
The wasp shown here is a male and like all male wasps it lacks any sort of sting. Ichneumon Wasp females possess an ovipositor that is normally incapable of delivering a sting. Instead it is used to parasitize the larva stage of a lepidoptera (butterfly of moth caterpillar). There are many species and separating them requires considerable expertise.
