Watching fireflies as they light up a soft warm night is one of the pure joys of summer. As fireflies dwindle and send their last signals of the season, we find out what all of that flashing is about.
In this Horticulture Day edition of Talk of Iowa, Chairty Nebbe talks with Iowa State University Extension entomologist Donald Lewis about the majesty and fertility of fireflies, the genesis of Hort Day, and the upcoming 30th anniversary celebration. Later, ISU Extension horticulturist Richard Jauron joins the conversation to answer listener questions.
