Parasitica (the parasitican wasps) is an obsolete, paraphyletic infraorder of Apocrita containing the parasitoid wasps.

[5] It includes all Apocrita except for the Aculeata.

Parasitica has more members as a group than both the Symphyta and the Aculeata combined.

[6] Parasitica also contains groups of phytophagous hymenopterans such as the Cynipoidea (gall wasps).
