Amblyteles armatorius is a species of parasitic wasp in the family Ichneumonidae first described by Johann Reinhold Forster in 1771.

The head and thorax of this large wasp are black, except the yellow scutellum.

This species lacks a sting, so the characteristic markings of many aculeate wasps represent a protective mimicry.

[7] Adults can be usually found in summer on flowers, especially Apiaceae species, feeding on nectar and pollen.

When they hatch larvae feed on their hosts, mainly Noctuidae and Notodontidae, but also some Geometridae, Erebidae, Saturniidae and Lasiocampidae (Calliteara pudibunda, Odontopera bidentata, Macrothylacia rubi and Saturnia pavonia).
