The Blue Mountains are a great destination any time of year but they have a special magic at night. One of the regions natural wonders is the glow-worms. These bioluminescent insects turn dark caves and tunnels into a starry sky of lights. To experience this magic you need to know the best time of year and the right conditions.
What are Glow-Worms?
Glow-worms are the larvae of certain fly species like Arachnocampa richardsae and are found in damp, dark places like caves, grottos and forested areas. They use their blue-green tail lights, a chemical reaction, to lure in nocturnal beetles and adult fireflies into their sticky mucous threads.
Best Time to See
The best time to see glow-worms in the Blue Mountains is during the warmer and wetter months, November to March when the conditions are perfect for their glow. Here’s why:
- Warm Weather: Higher temperatures means a consistent glow worm population.
- Higher Humidity: Wetter months means the damp conditions glow-worms need to survive.
- Longer Evenings: More twilight hours means more time for night hikes and exploring.
Glow-worms are active all year but the cooler months may see a decrease in their glow so summer is the best Blue Mountains tour time.
