Leucorrhinia glacialis (Crimson-ringed Whiteface)BC conservation rank: S5. Yellow List.Description: Can be confused with L. proxima, but its wings have two rows of cells (where shown in fig. 18a). Male's abdomen is mostly black, with red only at the base and without spots on top of the middle segments (though some have thin streaks). Young females have yellow marks on top of segments 1 to 7, sometimes turning red with maturity. Hamule, fig. 16e; vulvar lamina, fig. 17f. Length: male 36 mm, female 35 mm. Global range: Southeastern Alaska and British Columbia east to Labrador and Newfoundland; south in the western mountains to California, Nevada and Wyoming, and in the east to Minnesota, Pennsylvania, West Virginia and Maryland (Needham et al. 2000). Faunal element: Transition (see Appendix 2). BC Distribution: Widespread in southern and central BC, north to about 56ºN. Biology: Lives around marshy lakes and ponds, especially peaty ones, in forests and mountains. (e.g., Nuphar lutea associations; Wm01-02, Wm04-06; Wf01, 05-08, Wf10). Can be abundant in these places, but in general is not as common as L. proxima. BC flight period: mid May to early September; all records range from late May to late August.
