Dusona terebrator is a species of parasitic wasp belonging to the family Ichneumonidae, subfamily Campopleginae.

Petiole smooth or with fine sculpture laterally in front of the glymmae, at most with some transverse wrinkles anteriorly.

Dusona terebrator is very similar to other small species of Dusona such as D. leptogaster, D. admontina and in particular D. nidulator but can be distinguished by a combination of the sculpture of the mesopleuron and petiole, the coloration of abdomen, the number of flagellomeres, ovipositor index and other smaller characteristics.

[3][4] The known hosts are the Noctuid moths Athetis hospes, Caradrina morpheus and Charanyca trigrammica.

[2] Dusona terebrator is known from much of the Palearctic region: Austria, Armenia, Azerbaijan, Bulgaria, Belarus, Czech Republic, Finland, France, Germany, Italy, Moldova, Netherlands, Poland, Romania, Russia (including east Siberia), Slovakia, Spain, Sweden, Turkey, Ukraine and United Kingdom.
