Van Helsing gently held a glowing insect. “Behold the firefly, or lightning bug, known for its magical bioluminescence. These little beetles use light signals to communicate, especially during mating season.”
He continued, “Fireflies produce light through a chemical reaction in their lower abdomen, called bioluminescence. This glow attracts mates and sometimes warns predators that they taste bad.”
