Millions of mayflies showed up on radar Tuesday night—a sign of a healthy Lake Erie.

When the water temps start warming closer to 60 degrees, which it's doing in the western basin of Lake Erie, the midges start swarming. The larvae, or bloodworms, have been there for weeks. It's the warmth, though, that brings them to the surface. Next step in the midge life cycle is reproduction.

While mayflies are a nuisance, they are harmless.

According to Encyclopedia Britannica, there are more than 2,500 species of mayflies worldwide and about 700 in the United States. Adult mayflies’ lifespans are very short, lasting usually only several days.
