Join Ben for a captivating exploration of Texas enchanting fireflies, where you’ll discover the diverse species that light up the Lone Star State’s wild landscapes.

Ben will present his research on Texas firefly taxa, highlighting the fascinating species found in nearby river basins and riparian areas. He will show you how to identify common firefly species and learn their flash patterns so you can recognize them in the wild. You’ll also discover why fireflies flash and how they use light to attract mates. Additionally, he will discuss specific threats that are causing fireflies to disappear in many areas of the United States.

Ben will also explain how to certify your property as a firefly habitat, suggest native plants you can grow to help them, and share other ways you can contribute to saving these iconic insects.
