Glow-worms make sticky silk threads which hang like fishing lines. Small flying insects are attracted to the light of a glow-worm, and get caught in the threads. The glow-worm pulls in the thread with its mouth and eats the insect. In the bush the lines are 1–2 centimetres long. In caves, where there is no wind to tangle the threads, the lines may be up to half a metre long. A large glow-worm larva may have as many as 70 lines.
