Firefly Communication: Projects

Firefly flashes are more than a mere midsummer night’s wonder: they express a sophisticated social behavior 
characterized by male courtship and female mate choice.

Firefly Communication: Features

During mating season, males of synchronous firefly species flash in unison within swarms of thousands of individuals. These strongly-correlated collective displays have inspired numerous mathematical models to explain how global synchronous patterns emerge from local interactions. Yet, experimental data to validate these models remains sparse. 

Firefly Communication: Features

To address this gap, we develop a method for three-dimensional tracking of firefly flashes, using a stereoscopic setup of 360-degree cameras.

We apply this method to record flashing displays of the North American synchronous species Photinus carolinus in its natural habitat:

… as well as within controlled environments:

Our results show that even a small number of interacting males synchronize their flashes; however, periodic flash bursts only occur in groups larger than 15 males:

Moreover, flash occurrences are correlated over several meters, indicating long-range interactions
