What are fireflies and glow worms?

Fireflies, also known as lightning bugs, are bioluminescent beetles belonging to the family Lampyridae, famous for their ability to produce light through a chemical reaction in their lower abdomen, primarily to attract mates. Glowworms, which can refer to various species including some larvae of beetles and moths, are often found in damp environments and emit light to attract prey or mates. Both use bioluminescence for communication and survival, but they belong to different taxonomic groups and have distinct life cycles and habitats.
