Enallagma boreale (Boreal Bluet)BC conservation rank: S5. Yellow List.Description: Male's appendages, fig. 4e (the view from above is most distinctive). The rear half of female's segment 8 is black, and a pale area at the base is sometimes divided by a black line. Length: male 33 mm, female 35 mm (largest in the far north). Global Range: Alaska east to Labrador and Newfoundland; south to West Virginia, Nebraska, and along the mountains to New Mexico and California (Westfall and May 1996). Faunal element: Widespread Boreal (see Appendix 2). BC Distribution: Throughout BC and north to the Arctic treeline. Biology: One of BC's most abundant odonates. This abundance and its wide distribution is partly the result of its tolerance of a wide variety of habitats - it swarms around warm saline ponds (Gs01-03, Wm07) in dry grasslands, can be common along the marshy shores of lakes and ponds (Wm01-02, Wm04-06), and is a typical resident of cold peatland waters (Wf01, 05-08; Wb13, 50-52). Usually inhabits water bodies lacking fish. BC flight period: mid April to mid October; mainly from early June to mid August.
