Naming
Like many bluets in the genus Enallagma many species look similar to each other. The boreal bluet looks has similar to many bluet species. They include the northern bluet, familiar bluet, Hagen's bluet, marsh bluet, and vernal bluet. It can be distinguished from familiar bluet by the large postocular spots and the shorter cerci. The characteristics shared by northern and boreal bluets are their large eyespots, and a mushroom-shaped black spot on abdominal segment S2. Its best seen dorsally."Enallagma boreale" has two different subspecies. The following are the two subspecies:⤷ "Enallagma boreale boreale"

Status
Boreal bluet populations are currently widespread, abundant, and secure.
Habitat
The boreal bluet occurs along lakes, ponds, marshes, and streams with slow to moderate flow. This species occurs in a wide variety of habitats, from sagebrush desert to mountain lakes.The boreal bluet looks almost identical to the northern bluet. Even both of these species share similar ranges in North America, they are almost never found at the same body of water. Both the boreal bluet and the northern bluet are found early in the season. The reasons for this separation remains still unknown.
Reproduction
Male boreal bluets set up territories at their choice breeding sites. After both genders mate, the female boreal bluet oviposits in aquatic vegetation.References:
