Blue Dasher Pachydiplex longipennis

There are 88 species of dragonflies in British Columbia (including 24 damselflies and 64 true dragonflies). Dragonflies are usually larger than damselflies and have larger eyes that are closer together than those of damselflies. A distinguishing feature between the two is the wings: dragonflies have wings that are held perpendicular to the body, as opposed to damselflies whose wings are attached together and folded over the body.Generally, dragonflies require habitat that includes lakes, wetlands, small ponds, bogs,sedge marshes, and occasionally streams. Most dragonfly species lay eggs in the water or on aquatic plants. Eggs generally hatch and remain in the larval stage over winter.When ready to metamorphose into adults the larvae (or nymphs) usually climb onto a plant that emerges out of the water. There they will shed their skin and emerge as dragonflies. The larval stage can last up to a few years for some species, and the adult stage can last up to a couple of months. Alteration, destruction and loss of freshwater habitats are a major threat to dragonflies,as they require these habitats for breeding, larval life stages, and foraging.Learn about what species are in your area and encourage protection of local public aquatic habitats. Build your own pond in your yard or garden and watch for what wildlife comes to visit.
