The term 'Bioluminescent Beetle' is a reference to the firefly, an insect that produces light through a chemical reaction. Fireflies are known for their ability to produce light from their abdomens, which is used to attract mates and ward off predators. The light produced by fireflies is a result of a chemical reaction between luciferin and luciferase, which produces a cold light with no infrared or ultraviolet frequencies.
