Faunal element: Transition (see Appendix 2). BC Distribution: Widespread throughout BC, but on the coast known only from the Lower Mainland. Biology: Common in slow streams (e.g., Wm01), grassland ponds (Wm04, Wm07, GS01-03), cattail and bulrush marshes (Wm05, Wm06) and peatland pools (e.g., Wf07).
