Fireflies emit flashes of light because of chemical reactions, which occur in their abdomens. The rate of the chemical reactions
damaskus [11]

Since the rate of flashing depends on the rate of reaction, it means that fireflies will flash slower during cold weather.

<h3>How does temperature affect rate of reactions?</h3>

Temperature affects the rate of reaction such that reactions are faster at high temperatures and slower at low temperatures.

Thus, since the rate of flashing in fireflies depends on the rate of reaction, cold temperature means that the rate of flashing will be low as compared to warm temperature.

In other words, fireflies will flash lower during cold weather and vice versa.
