Episode description

This week’s episode of the Backyard Ecology podcast is the conclusion of our conversation with Lynn Faust. Lynn is the author of Fireflies, Glow-worms, and Lightning Bugs: Identification and Natural History of the Fireflies of the Eastern and Central United States and Canada.

In this episode, we continue to just geek out about lightning bugs. Once again, this is a very informal conversation that includes stories and more educational content. If you haven’t listened to the previous episode, then I encourage you to go back and listen to Episode 15, which is part 1 of this conversation.

We ended the previous episode talking about the larvae of the Pyractomena or Spring Tree Top Flasher fireflies and how they are so special because they pupate on the sides of trees where we can see them. And they do this in the late winter / very early spring, basically the late Feb. or early March timeframe in Kentucky and Tennessee. We jump right back into that conversation with Lynn describing some of Pyractomena’s mating behaviors and why they might choose to come out so early.

Much of the story of lightning bugs and fireflies revolves around the theme of just paying attention, making observations, sharing what you see, and asking questions. People doing those things have led to the discovery of new species like the synchronized fireflies of the Smokies and the Low Country Ghost. Other people have been able to help better document the range of a given species like the Pink Flashers. Those activities have also led to recognizing previously overlooked behaviors like the fireflies nectaring on milkweeds. There’s so much out there to learn and discover if we’re willing to open our eyes and pay attention.

Lightning bugs, like many other insects, also face some threats. The main threats to lightning bugs are light pollution, pesticides in the soil, soil compaction, and habitat loss. Lynn talks about these threats and realistic ways that we can make our yards more firefly friendly. She takes a very balanced approach that basically boils down to being aware of how your actions might affect lightning bugs or other organisms and then making the best choices for you and your situation. I, for one, appreciate that balance. Lynn also shares some tips for observing lightning bugs.

Again, if you missed the first part of this conversation, then I encourage you to go back to episode 15 and listen to it. In that episode, Lynn shared the story of how she went from just watching the lightning bugs to becoming “The Lightning Bug Lady.” We also talked about some of the different species found in the eastern U.S., how to identify firefly species, and the general life history of fireflies. I hope you enjoy both these episodes.
