  A low dimensional nonlinear model based on the basic lighting mechanism of a
firefly is proposed. The basic assumption is that the firefly lighting cycle
can be thought to be a nonlinear oscillator with a robust periodic cycle. We
base our hypothesis on the well known light producing reactions involving
enzymes, common to many insect species, including the fireflies. We compare our
numerical findings with the available experimental results which correctly
predicts the reaction rates of the underlying chemical reactions. Toward the
end, a time-delay effect is introduced for possible explanation of appearance
of multiple-peak light pulses, especially when the ambient temperature becomes
low.
