Description

This study presents a time-delayed analysis of a firefly flash model derived from the bioluminescent mechanism of fireflies[1]. The model is formulated on the basis of the well-established enzymatic reactions responsible for light emission. Numerical findings are validated against experimentally reported results. Additionally, multiple peak pulses at low temperatures, including double peak pulses that appear through period-doubling bifurcation, are satisfactorily explained by the time-delayed firefly model.
