Essential Tips for Free Glowworm Watching

Stay quiet and still – Glowworms don’t like noise or sudden movement.
Wear good shoes – Some hidden gem locations have muddy or rocky paths.
Take photos the right way – Use a tripod and long exposure settings for clear glowworm pictures.

Fun fact: A single glowworm can produce light as bright as a candle flame—but they must remain undisturbed to keep glowing!

FAQ: Everything You Need to Know About Glowworms

Q: Are glowworms actually worms?

No, glowworms are not true worms! They are actually the larvae of fungus gnats. They glow to attract insects into their sticky silk threads, just like a spider catches prey in a web.

Q: Can I touch a glowworm?

No, never touch glowworms. They are fragile creatures, and touching them can damage their ability to glow or survive. Instead, enjoy them from a distance.

Q: Do glowworms only live in caves?

No! While many people think of glowworms in caves, they also live in forests, along riverbanks, and even on damp rock walls. This guide lists some of the best hidden gem spots where you can see glowworms in different environments.

Q: How long do glowworms live?

Glowworms spend 6-12 months as larvae, glowing to attract food. Once they turn into adults, they only live for a few days—just enough time to reproduce before their life cycle ends.
