I’ve heard reports of massive dragonfly swarms from around Ohio over the past few days. Most of these insects are probably Common Green Darners (the species in the accompanying photo) and Wandering Gliders. These species are highly migratory, and migrant swarms become conspicuous when they descend to feed near the ground. The dragonflies are mostly capturing gnats, winged ants, mosquitos and other small flying bugs. Please comment if you’ve seen such a swarm, along with the general location and date/time, and an estimate of the number of dragonflies. The following link goes to a more detailed article about this phenomenon:
