Small, brilliant pin head size lights decorated the ceiling of the cave. These creatures are not really worms but rather they are the larval stage of a small fly.
They mainly live in the rainforest or permanently wet caves. We waited until sunset and then the colony of thousands of glow-worms began to glow.
I’m not sure what makes them glow but there is common belief it’s the sun shining out their bum.
I choose to believe this myth because it’s hard to be unhappy when the sun shines out of your bum. Sometimes I wish I was a glow-worm.
