Status of Western River Cruiser Macromia magnifica McLachlan in British Columbia Cannings, S.G.
2003

Abstract: The Western River Cruiser, Macromia magnifica McLachlan, is a large, boldly patterned dragonfly of warm, clear streams and lakes in western North America. In British Columbia, the species is restricted to a few lakes and warm streams in the Fraser Valley, Shuswap Lake, Okanagan Valley and Christina Lake areas. Recent observation or collection records are not known from the Fraser Valley and Shuswap Lake. Little is known of the biology of the species and no real trend information is available. Possible threats include shoreline development (including loss of riparian vegetation), pesticide contamination, eutrophication and predation by introduced fish. Recommendations include more focused inventory, basic research into the speciesí biology, maintenance of natural shorelines where possible and control of introduced predatory fish.
