Approximately 2.8”, the subarctic darner is a large-sized dragonfly. Their bright, yellow face has a black cross line and short eye seam. Their brown thorax displays yellow and blue stripes that become more spotted across their black abdomen. Male and female subarctic darners are similar in appearance with females having a more robust abdomen.
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.
Nymphs eat a wide variety of aquatic insects and even very small fish and tadpoles. The adult’s diet mainly consists of soft-bodied flying insects like mosquitoes.
The darner is active early June to early October. Females oviposit their eggs on sphagnum, mosses, and sedges along the waterline.
