Arachnocampa richardsae
Glow-worms
Greater Sydney / Blue Mountains
NSW, Australia
Glow-worms are insects having a bioluminescent larval stage.
The roof of a cave / overhang covered with glow-worms can look remarkably like a blue starry night sky ... due to the collective bioluminescent glow from the larvae.
The larva hangs down sticky silk threads from the ceiling of a cave. The glow from its head attracts prey and ensnare them in the threads.
Generally glow-worms have few predators.
Their greatest danger is from human interference.
