Like other perilampids, it is likely a hyperparasitoid, with larvae that develop as of other parasitic insects. The has been recorded from Louisiana, Maryland, Minnesota, New York, and Ontario, suggesting a broad distribution across eastern and central North America.

Ecological Role

As a member of the Perilampidae, this likely functions as a hyperparasitoid in . Perilampid larvae typically parasitize other parasitic insects such as tachinid flies, ichneumon wasps, or braconid wasps that are themselves living as inside caterpillars or other insect larvae. This places them at the fourth in some .
