Amazing Adaptations of Aquatic Insects

Lunchtime Lectures
Wednesday, May 26, 2021
1:00 p.m.–1:45 p.m. EDT (UTC -4)

You may not know it, but many insects live most of their lives underwater—including dragonflies, mosquitoes, black flies, some beetles, and many “true bugs.” Insects, the most diverse class of organisms on Earth, have incredible, ingenious, and even beautiful adaptations to their environments, and aquatic insects are no exception. Learn about caddisfly art, mayfly mating rituals, and scuba diving beetles, along with a surprising Guinness Book world record held by a tiny, tiny bug!

Stefanie Kroll is head of the watershed ecology section of the Patrick Center for Environmental Research, a senior scientist, and assistant research professor at the Academy of Natural Sciences of Drexel University. She and her talented colleagues run a macroinvertebrate lab where they identify insects to use as indicators of water quality. She has authored peer-reviewed papers on the effects of human activities on aquatic biological communities using insects, diatoms, and fish as multiple bioindicator groups. Kroll is also interested in recovery of these communities after restoration, and climate change effects on stream biodiversity and resilience. She is passionate about mentoring to increase diversity and inclusion in the environmental sciences. She also teaches yoga part-time and enjoys hiking with her dachshund, Gertie.

About the Series

Now combined with our Saturday Speaker Series, Lunchtime Lectures take a rigorous and entertaining approach to exploring topics for scholars and anyone interested in stories about the history of science. The talks help expand perceptions of the nature of science and how it’s done. This season, we’re showcasing historians and scientists whose work analyzes the past, present, and future of environmental science.
