Penn State researchers help shine light on firefly populations in the eastern U.S.

Fireflies can bring magic to summer nights — blinking in yards and putting on light shows in fields. But a study by a team that includes researchers from Penn State found that while fireflies' overall populations did not decline, climate change and loss of habitat do have an impact on the winged beetles.
