Trissolcus oenone is a small black wasp, 1–2mm in length (depending on host), and shares many morphological similarities with other Australian Trissolcus species.
The New Zealand population can generally be separated from other New Zealand Trissolcus species based on the colour of parasitised eggs, and the colour of the legs and antennae.
Pentatomid eggs parasitised by Trissolcus oenone develop a black ring near the top of the egg, whereas those parasitised by T. basalis turn almost entirely black.
Adult specimens of T. oenone have black patches on the bases of the legs, while T. basalis legs are uniformly orange.
