The robust baskettail reaches its northern limits in New Jersey where it inhabits flood plain swamps and marshes along the coastal plain.


Predatory larvae and adults feed on other invertebrates.


The robust baskettail emerges as early as mid April and has been observed until mid May. Females release large masses of yellow or orange eggs on or near emergent vegetation while in flight.


Due to a scarcity of habitat, the robust baskettail is considered Threatened in New Jersey.
