The only member of the genius Hagenius, they are the largest of the North American dragonflies, averaging 3.3 inches long. They are fairly easy to identify due to their large size and their habit of flying with their abdomen curled under in a sort of "J" shape.
The dragonhunter is legendary for their ferociousness. They have been known to eat large butterflies and dragonflies, this includes other large dragons such as darners, clubtails and even other dragonhunters. They are immune to some types of wasp poisons and to the toxins that build up in monarch butterflies due to their milkweed diet. Typically when hunting they ambush from above, dropping down on their prey like the river jewelwing damselfly that this dragonhunter is eating.
