The firefly is a small nocturnal flying beetle that emits a glow from its body due to a natural chemical stored in its abdomen. These bugs are from the same family as glowworms and are the only winged luminescent bug. They are approximately 2 cm long and have a lifespan of around 2 months. They are usually light brown in colour and can be found in the summer evenings in a variety of warm humid environments (they require a moist environment in order to survive).
They feed on pollen, larvae, slugs, snails and worms. The adult fireflies are responsible for the intermittent light (which is also used as a means of communication between this species). A beautiful sight to observe when there are lots of them flying around resembling twinkling stars in the night sky.
