This week, thick clouds of millions of mayflies emanated from the Mississippi River in Northeast Iowa.
There were so many of them that the National Weather Service picked up radar surveillance of what looked like rain.
It's Horticulture Day on Talk of Iowa. Guest host Emily Woodbury talks mayflies, mosquitos, and all things insect with Donald Lewis, Iowa State University Extension Entomologist. And, Richard Jauron joins the show to answer listener plant and garden questions.
