Mayfly season begins in the Midwest

Any day now, the Mississippi River is going to give us what the Illinois River gave the people of Havana, Ill., southwest of Chicago, today.

It’s mayfly season.

At one point, about 6 inches of mayflies were piled up on a bridge over the river.

It’s been a few years since the Mississippi mayfly hatch occurred in June, however.

Last year, the La Crosse, Wis., area was hit with the hatching from the mud bottom of the river on July 4.

The worst hatch — or best, depending on how you feel about this sort of thing — in northern sections of the river occurred in Hastings in 2012 when two cars collided on the Highway 61 because of the slippery road caused by the dead flies.

Last year’s hatch in Hastings also occurred on July 4.

What’s really happening here is some mayfly love.

Before they die — anywhere from a few minutes to 24 hours after emerging — males and females find one another, and drop as many as 3,000 eggs back into the water.

    I was told by relatives who live in La Crosse, and who have the need to see the positive side of this, that a big hatch is a sign of a healthy river. Yippee/Yuck!! Looks as though it is very healthy!!

    Eagerly awaiting a made-for-SyFy network film about this. Add some D-list talent along with a hokey title and boom, ratings winner!

    I think they should harvest ’em and put ’em in protein bars

        Except Snowpiercer was… not quite insects.

          Insect protein bar were what the people on the back of the train were eating…

            I totally blocked that out in light of the other thing.

    Saw a mayfly at Stately Moffitt Manor on the weekend. Nice snack, if you’re a trout.
