Luminous Landscapes: Fireflies in the Heart of Texas – Williamson County Chapter Meeting, April 10

April 10 @ 7:00 pm 8:30 pm

[Update published to Zoom registrants and Wilco subscribers on April 9=> Due to unforeseen circumstances, the Zoom portion of this meeting was cancelled and the meeting was not recorded.]

Join NPSOT-Williamson County on Thursday, April 10, 2025, when our featured topic will be “Luminous Landscapes: Fireflies in the Heart of Texas” with Ben Pfeiffer. Free and open to the public. The meeting begins at 7:00 PM.  The guest presentation begins after a short business meeting. 

About our topic: This highly educational and fun talk will discuss the types of fireflies (Lampyridae) found in Texas and across the United States. 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.

About our speaker: Ben Pfeiffer is founder of Firefly Conservation & Research (at firefly.org), a firefly conservation and educational organization working to conserve fireflies and their habitats through conservation, education and research efforts.

A recognized public speaker and science educator, Ben’s research work focuses on Texas firefly species. He is working to document the Texas and Southwest firefly diversity and its natural history regarding their life cycle, preferred habitat and unique flash patterns. His research is helping to illuminate much of this never before collected information about Texas’s incredibly rich firefly diversity so that others can work to preserve and enjoy it.

Ben is a member of the International Union for the Conservation of Nature (IUCN) Firefly Working group. He recently completed the Red List Extinction Risk Assessments for Texas firefly species. Ben studied Biology at Texas State University and is a certified Master Naturalist. He is a lifelong 6th generation Texan and has spent most of his life working to understand Texas ecology and its unique diversity.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
