Stenarella domator

Member of the subtribe Osprynchotina; identification to genus in the Nearctic region requires reference to the key provided in the primary source distinguishing Nearctic genera of this subtribe. Specific diagnostic features for S. domator relative to other Stenarella species are not detailed in available sources.

Nests of aculeate Hymenoptera constructed with mud or earth. The species occupies the nest microhabitat of its hosts rather than free-living vegetation.

Native to the western Palaearctic region with confirmed records from Belgium, Denmark, and Norway. Introduced to and established in the Nearctic region; specific Nearctic localities not detailed in primary source.

Ectoparasitoid development on aculeate Hymenoptera hosts within mud/earth nests. Specific details regarding egg placement, larval instars, pupation site, or developmental duration are not provided in available sources.

Parasitoid of ground-nesting or mud-nesting aculeate Hymenoptera. As an introduced species in the Nearctic, its ecological impacts on native host populations remain unstudied.

Documented as an adventive species in the Nearctic ichneumonid fauna; implications for biological control or pest management potential are not assessed in available literature.
