Diplazon laetatorius is a hover fly parasitoid wasp in the Diplazontinae subfamily of the Ichneumonid wasp family (Ichneumonidae). ^[2] It was first described as Ichneumon laetatorius in 1781 by Johan Christian Fabricius. ^[3]

Ecology

Adult Diplazon laetatorius feed on floral nectar, with a preference for flowers in the umbellifer family. Females lay their eggs on or near the eggs and larvae of hoverflies (Syrphidae). The developing parasitoid larvae consume the host from within, eventually completing development and emerging as adult wasps. ^[4]
