Glow worms live in dark, damp, and humid environments where they can build their sticky snares to catch prey. They are typically found in caves, rainforest gullies, old mining tunnels, and areas with running water nearby such as streams or waterfalls. These habitats provide the shelter, moisture, and darkness necessary for their bioluminescent glow to function effectively for attracting prey. In Australia and New Zealand, glow worms are found in rainforests, caves, and near waterfalls. In Britain, they are often found in grasslands, woodland edges, and hedgerows, particularly in chalk or limestone areas. Glow worms prefer habitats with still, moist air to prevent their delicate bodies from drying out, and they need places where their flying insect prey are abundant.
