(Fox 4) – Dragonflies were out in full force this week in parts of the United States. In fact, the apparent swarms were so massive, they were picked up on weather radars Tuesday across three states, according to the National Weather Service. Swarms could be seen over portions of Indiana, Ohio and Pennsylvania in images released by the National Weather Service in Cleveland, which confirmed that it wasn’t rain being observed. “While we are not biological experts, we have determined —
through input from our followers — that it’s most likely dragonflies mixed with other insects/birds,” the NWS Cleveland posted on Twitter. Many also posted about their run-ins with the insects on social media. Entomologists know that dragonflies swarm for various reasons, but little is known about the behavior, according to the Dragonfly Swarm Project — a large-scale study open to the public on dragonfly swarming.
