Boreal Bluet in Detail.

Enallagma boreale, commonly known as the Boreal Bluet, is a species of damselfly found in North America. It belongs to the family Coenagrionidae and is one of the smallest damselflies in the region, with a length of approximately just over an inch (30-35 mm).

The Boreal Bluet has a distinctive blue and black coloration, with blue on the upper side of the thorax and black on the sides and lower portion. The abdomen is blue and black, with black markings on the upper segments. The eyes are bright blue, which distinguishes it from other species of Enallagma damselflies.

This species is found in a variety of freshwater habitats, including lakes, ponds, and slow-moving streams, usually in forested areas. They are active during the summer months, from late May to early September, and are known to be territorial.

Like other damselflies, the Boreal Bluet has a complex life cycle, with eggs being laid in the water and hatching into aquatic larvae that undergo several molts before emerging as adult damselflies. The larvae are important predators in freshwater ecosystems, feeding on a variety of small aquatic invertebrates.
