People of all ages are invited to the annual butterfly count Saturday at the University of Louisville’s Horner Wildlife Sanctuary in Oldham County.

The count will be led by U of L biology professor emeritus Charles Covell, who speaks here with WFPL’s Rick Howlett about the purpose of the count and what you need to know to participate.

Covell organized the Society of Kentucky Lepidopterists for the study of butterflies and moths in 1974. He authored “Butterflies and Moths of Kentucky” and the 1984 Peterson “Field Guide to Moths of Eastern North America.”
