The River Jewelwing, Calopteryx aequabilis Say, is a large, spectacular damselfly restricted in British Columbia to a single site, Christina Creek. This short stream is the warm, clear outlet of Christina Lake and flows into the Kettle River, 18 km east of Grand Forks. Populations are not large; a maximum of 28 adults have been counted on one date. Western populations of the species are quite spotty and this population is probably isolated from the nearest ones in Washington State. The Kettle River has not been well surveyed; there is an unconfirmed sighting from that river near Grand Forks. The jewelwings are unusual among damselflies in having male courtship displays. Females lay eggs in floating or underwater vegetation, and larvae develop for two or three years before emerging as adults. Because this species was only discovered at Christina Creek in 1999, there is no information on population trends. The habitat is still predominantly natural, but threats or potential threats include exotic fish, riparian
