Alomya debellator is a species of parasitoid wasp in the family Ichneumonidae. It was first described by Johan Christian Fabricius in 1775.
Alomya debellator can reach a length of 10.5–18 mm. The head, thorax and upper legs are black, whilst the abdomen and lower legs are mainly orange with black markings or a broad black band.
Adult wasps feed on aphid honeydew and nectar of Anthriscus sylvestris and Heracleum sphondylium . They can be found from May to September. The females of this parasitoid wasp lay their eggs into the caterpillars of moths, mainly Autographa gamma , Hepialus lupulinus and Euthrix potatoria . When they hatch, the larvae feed on their hosts.
A. debellator is present in most of Europe.
This species prefers hedgerows and meadows.
