Habitat
Boreal Bluets can be present in a variety of habitats including fishless ponds and lakes, open marshes, peatland pools and slow streams, all with abundant emergent vegetation. This species is quite tolerant of alkaline, salty conditions (Westfall and May 1996, Acorn 2004, Paulson 2009).

Food Habits
Larvae feed on a wide variety of aquatic insects, such as mosquito larvae, other aquatic fly larvae, mayfly larvae, and freshwater shrimp.
Adult- This damselfly will eat almost any soft-bodied flying insect including mosquitoes, flies, small moths, mayflies, and flying ants or termites.
Reproductive Characteristics
Male Boreal Bluets patrol over open water and perch on emergent vegetation. Copulation and oviposition site exploration are lengthy. Tandem pairs oviposit at the water surface and females submerge below water to oviposit as well (Acorn 2004, Paulson 2009).
