Western Flying Adders, like most other dragonflies, can be found near streams and woods. This particular species is "western" thanks to a range that lies west of the Rocky Mountains and north into Canada. Unlike other dragonflies, Western Flying Adders are not particularly aggressive toward other species of dragonflies.
In early spring, females will insert their eggs into soft wood or plants near creeks or streams using a long syringe-like ovipositor. The young, hairy naiads (juveniles) hatch and then make their way to into water and burrow into the sandy or silty bottom. They emerge from these hiding spots to feed on other aquatic insects using their large spoon-shaped lower lip. They mature rather quickly and are fully developed adult by late spring.
