This species prefers marshes and bogs with plenty of sphagnum growth. The Hudsonian whiteface is only found in northern New Jersey in few colonies.


Nymphs feed on a variety of aquatic insects and will also eat small fish and tadpoles. Adults will eat soft-bodied flying insects including mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites.


Emergence is throughout May and mature adults can be observed from June into early July.


The Hudsonian whiteface requires habitat that is rare in New Jersey and therefore is considered a species of Special Concern in New Jersey.
