Species distribution map

Range & Habitat:

Recorded only from Sussex and Morris counties, this species should be looked for in other areas of the Highlands and Ridge & Valley provinces.

Boreal Bluet male lateral 

Description:

Largely blue, with a relatively narrow black humeral stripe, it is virtually identical to the more common Northern Bluet.  The postocular spots are large and rounded-triangular, narrowly separated from a thin occipital bar.  Can be distinguished from Familiar Bluet by the large postocular spots and the shorter cerci. Can be told from the Hagen's/Marsh complex by the size and shape of the postocular spots and possibly by the nearly all black S10.

 

Conservation Status:

State: S1S2 - Imperiled to critically imperiled in New Jersey

Global: G5 - Secure globally, but possibly rare in parts of its range
