Paradox of the Synchronous Symphony

Synchronous fireflies certainly highlight Earth’s natural magic, yet such cooperative behavior presents quite a thorny scientific paradox!

We do know how some fireflies manage to synchronize their flashing, thanks to work done in the 1960’s by John & Elisabeth Buck (previous post). For instance, male Pteroptyx fireflies in southeast Asia can reset their internal timekeeper whenever they see a neighbor’s flash. Inspired by Steve Strogatz’s book, Sync, Nick Case made a spectacular simulation to illustrate how this works – I’ve played with it for hours, and you can, too!

But why do fireflies synchronize? Why should thousands of males so carefully coordinate their behavior to flash in unison, all of them marching to the beat of a single drummer? According to sexual selection theory, these males should be competing fiercely  with each other for the chance to mate. So why synchronize?

Those Invisible Lines of Connection

Invisible lines of connection run through all our lives, knitting them together. Those lines  burned brightly for me yesterday,  when I met John Buck’s daughter and grand-daughter.

John Buck (1913-2005) was a towering figure in firefly science. He dedicated his life to deciphering how these luminous creatures manage to control their flashes, aided in his research by Elisabeth, his wife of 65 years. Deeply fascinated by firefly synchrony, they traveled to Southeast Asia to study how thousands of males manage to match up their rhythms. Continue reading
