Arachnocampa is a genus of glow-worms found primarily in Australia and New Zealand. These bioluminescent larvae are known for their unique silk threads, which they use to capture prey. The light emitted by the larvae attracts insects, which become ensnared in the sticky silk. The life cycle of Arachnocampa includes several stages, starting from eggs to larvae and eventually to adult flies. The larvae can glow for several months, while the adult flies are short-lived and do not feed. This fascinating organism plays a role in the ecosystem by controlling insect populations.
