Raiders and bandits who ride flying vermin prefer giant dragonflies to other mounts. They're less aggressive than wasps but more so than bees. They also make a distinct thrumming sound in flight that strikes fear into common folk.
Riders prefer to use female dragonflies, since males are very territorial. A giant dragonfly is 10 feet long with a 10-foot wingspan. Its body is only 2 feet wide.
