The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The super family is made up of the ichneumon wasps (often inaccurately called "ichneumon flies"; family Ichneumonidae) and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.
