Yup. This happened because I recently had a chat about all things firefly with Alie Ward for her amazing Ologies podcast! Learn how these tiny insects illuminate the night, some dos and don’ts of watching fireflies, choosy females, nuptial gifts, California pink glowworms, light pollution threats, little-known fireflies of the Western USA, and how you can help the world stay aglow with these beloved bugs.
Watching a whole forestful of fireflies flashing together in unison is a truly mesmerizing experience. As I described in an earlier post, males of only a few firefly species are capable of this remarkable feat. Although we still don’t know why this behavior occurs, some researchers at the University of Colorado – Boulder recently developed cool tools to shed new light on how fireflies accomplish this collective behavior.
Using Go-Pro cameras to film Photinus carolinus in the Great Smoky Mountains National Park, Raphael Sarfati and Orit Peleg were later able to reconstruct the 3D flight paths of individual male fireflies. You can read about their study in this month’s Smithsonian Magazine, or check out their original paper in the Journal of the Royal Society Interface.
Their findings provide clues into how insects with relatively small brains can perform such seemingly complex synchronous behaviors. By demonstrating how fireflies kick off their synchrony, this research will inspire new advances in swarm robotics. In the future, their tracking methods could also be adapted for community science projects like Firefly Watch in the U.S. to help scientists monitor long-term trends in firefly populations.
So excited to announce that we just published the first-ever comprehensive review about the threats facing fireflies around the globe!
In this article we also describe several things we all can do to give fireflies a brighter future. You can read our article here (we’re tremendously grateful to BioScience for making this Editor’s Choice & freely available).
I’m also delighted to announce my upcoming 1-year sabbatic leave from teaching at Tufts University, starting in May 2020. I’m looking forward to spending more time working on several firefly conservation initiatives, including serving as co-chair for the IUCN Firefly Specialist Group and working with my colleagues at Fireflyers International.
In the meantime, you might enjoy this great article in The Guardian summarizing the work that we & many others have been doing to keep the firefly magic alive!
