Northern Bluet

Dennis Paulson assures us that this dameselfly is a Northern Bluet. We found just one flying along a forest trail on 10 May 2020 at the Darlin Creek Preserve just south of Olympia. This species is often common but hard to tell from a Boreal Bluet. Many observers combine the two species into one, calling both NoBo Bluets. If you enlarge this photo and look at the upper terminal abdominal appendage, you can see that has a tiny, sharp spine, The same structure is oval on a Boreal Bluet and looks a bit like a shark’s fin on another similar damselfly, the Familiar Bluet.
