![]() As the adults are unable to feed, Glow Worms must gain enough sustenance during the larval stage to get them through the rest of their lifecycle. “ The adults are delicate flies that do not have working mouthparts, and as such, only live for a small number of days (females two days, males six days). That works fine when the moon and stars are real,” said Dave Merritt, a biologist at the University of Queensland in Brisbane, Australia, “ but when the source is close they end up spiraling into it.”Ī glow worm measures about 3-5cm. They keep the celestial bodies at a constant angle to fly in a straight line. Many of these insects, including moths, navigate by starlight. That’s where the ‘‘glowing” comes in the picture. But being in the larva stage they can’t go looking for food, so these clever creatures instead attract food towards them. ![]() Glow worms are carnivorous, and hence feed on small insects. Similar to maggots which grow into common houseflies, glow worms grow to become fungus gnats.Īlthough they are most spectacular in caves, glow worms are also quite common outside – they can be found wherever conditions are damp, food is in good supply and there is an overhanging wall. They are in fact the larvas of a small fly called Fungus Gnat. Despite their excotic name, they aren’t actually worms! These creatures are commonly known as glow worms and scientifically as Arachnocampa. What’s so special about them and how do they emit this light? However, they are neither stars nor special lights lit for your grand entrance! Rather, they are creatures that emit light and live on the ceilings of caves. You may mistake them for stars that twinkle at night. WHILE gliding through a dark cave in Australia or New Zealand, you may notice shimmering lights above.
