Naming
Hudsonian whitefaces are similar to ''Sympetrum'' species in appearance and behavior in some cases. Species within this genus are similar-looking and change in appearance as they age.
Distribution
The Hudsonian whiteface is found in an area stretching from Alaska to Labrador and from the Hudson bay to northern West Virginia.
Status
Populations of this species are widespread, abundant, and secure.Habitat
Hudsonian whitefaces are usually found at vegetated ponds, sloughs, sand-bottom lakes, bogs, and fens. The bogs are at higher elevations.The naiads of these dragonflies live in submerged vegetation. They don't actively pursue prey but wait for it to pass by. This strategy affords them protection from other predators. Naiads change to adults at night. Many records of this species is sparse, adults are believed to fly from late May to mid-August. They also fly at different times. The hunting occurs from the shoreline vegetation, where this species perches. Many specimen from Idaho tend to be larger than those found further north in its region. Hudsonian whitefaces have been known to swarm over sphagnum bogs in the northern part of its range.Reproduction
After mating, a male guards a female to prevent other males from mating with her. He does this by flying above her while she laying her eggs. It drives away other potential mates or maybe dragonflies of other species. The female lays her eggs by dipping the tip of her abdomen in the water while hovering above the surface.References:
