If you've been anywhere along with the Lake Erie shore, you've seen them.
Mayflies are everywhere!
This year, the swarms of midges and mayflies overlapped, but the good news is... they are a great indicator of a healthy lake.
Mayflies are usually more common in the west end of the lake and have shown up on Toledo and Detroit weather radar.
"Mayflies are about two to three times the size, they've got larger wings, and they've got three little tails that come out the back of them so that's one way you can identify them," Cleveland Metroparks naturalist Jake Kudma told us. "Same basic story as with the midges, birds will love them, frogs will love them, but we don't really have to worry about bites or anything."
Mayflies have gotten so thick in the past, they've caused traffic accidents. Many towns in western Ohio even shut off their street lights so they aren't attracted to them.
They're not around long, just like midges. Once they mate, they die.
