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

D. admontia is very similar to other small species of Dusona but can be distinguished by a combination of the 3rd gastral tergite being separated from the epipleuron by a crease, the mesopleuron being densely rugose-punctate with the interspaces coriaceous and rather dull, the coloration of abdomen and the number of flagellomeres.

[4][5] Dusona admontina has a short flight period between July and September.

Females attack and lay their eggs in the larvae of the moth Herminia grisealis.

The wasp's larva kills the host during its pupal stage and then spins a cocoon inside the now hollow pupa.
