DISTRIBUTION AND HABITAT

This species reaches the southern-most end of its range in northern New Jersey. Currently, the subarctic darner has only been found in Sussex County inhabiting swamps, bogs, and fens with abundant mosses.

LIFE CYCLE

The darner is active early June to early October. Females oviposit their eggs on sphagnum, mosses, and sedges along the waterline.
