They’re back! Watch as muckleheads swarm in clouds over Cleveland

CLEVELAND, Ohio -- Warmer temperatures are here, and that means muckleheads!

They were out in full force Thursday morning.

Huge clouds of the little bugs were swarming over the Shoreway in Cleveland.

Muckleheads are insects that hatch from Lake Erie in the late spring each year and push inland.

They don't bite; they are just very visible and swarm what's in their paths.
