Dragonflies and Damselflies Discussed at Lake Lessons

Adult dragonflies and damselflies are showy, beautiful and noisy. Visit a wetland area on a summer day, and chances are you’ll hear two males battling over territory or enjoy a demonstration of their speed and agility as they pursue their prey. Both dragonflies and damselflies are fierce predators, but how do you tell the difference?

On July 25, research scientist Bob DuBois, will present “Enjoying the Dragonflies and Damselflies of Door County,” as part of The Ridges Sanctuary summer speaker series, Lake Lessons, at the Baileys Harbor Town Hall. The program is free to the public and begins at 7 PM. Donations are welcome.

DuBois will focus on the many fascinating aspects of the biology, ecology and behavior of the dragonflies and damselflies of northeastern Wisconsin and will also give tips for identifying them. DuBois is the founder and current president of the Wisconsin Dragonfly Society (WDS) and will provide information on the newly formed organization, as well as how people can become involved in Wisconsin’s statewide dragonfly and damselfly survey (WOS).

DuBois has also published field guides to the Damselflies of the North Woods and to Dragonflies and Damselflies of the Rocky Mountains and has written over three dozen scientific research articles on various topics related to the management and protection of dragonflies, damselflies, and stream trout fisheries.
