The process of mating is in a wheel position often for an extended period of time. Oviposition can happen alone or in tandem. After mating, the male may release the female and both land. During oviposition, the male will guard around her, whereas the female will either fly up to drop eggs or just perch to lay eggs into shallow water. The eggs then overwinter and hatch in the spring (Paulson 2009). The adults emerge in the evening (Lung and Sommer 2001) when the flight season begins.
Conservation Very widespread species in North America (Lung and Sommer 2001). Diet Info Bottom dwelling aquatic nymphs feed on many small soft body arthropods and vertebrates in water. Terrestrial adults feed on many small soft-bodied flying insects (Lung and Sommer 2001). Range Rare in northeastern North America. This species ranges from British Columbia east to Ontario and Nova Scotia, and from southern Northwest Territories south to Kentucky, Virginia, and Maryland (Paulson 2009).
