Fireflies

 

Fireflies are beetles that light up forests, fields, and marshes near bodies of water because they require a moist environment to survive. To attract mates, males flash in a specific pattern to let the ladies know theyre available. Interested females glow in reply, and their flashes help the males find them. Those flashes of light also help fireflies defend territory and to scare off predators.

How Fireflies Glow

 

Their light is a form of bioluminescence (100 percent light, not heat) that is emitted from firefly eggs, larvae, pupae, and adults. Two chemicals found in their tails react to form light—Luciferin is heat resistant and provides the glow (yellow, green or orange light); Luciferase triggers the flash. Firefly populations are in decline due to habitat destruction and light pollution.

 

Human light pollution may be interfering with firefly flash patterns causing lower reproduction rates.
