The cypress firefly or lightning bug, (Photuris walldoxeyi) was first documented in early 2019 in high-quality cypress swamps in Mississippi,
Tennessee and Indiana. A confirmed Illinois sighting was recorded at the Heron Pond boardwalk in June 2019. Natural heritage biologist
Christina Feng will tell us about fireflies of Illinois while leading a night hike on the Todd Fink-Heron Pond Trail to the Heron Pond boardwalk in search
of the cypress firefly. Meet in parking lot for the trail.
