Group of fireflies in a forest


Fireflies are best known for the enchanting light emitted from their abdomens. The yellows, greens and reds result from a chemical reaction known as bioluminescence, used to attract both mates and prey. Males flash at night and if a female is impressed by the display she will flash back. If she isn't, she remains hidden in the dark. There are 2,000 species of these winged beetles, found in damp meadows and marshes. If enough gather together, it's rumoured to be possible to read a book from their light. There are day-flying fireflies that don't produce light.
