Planning to catch a glimpse of glow worms in New Zealand? This rare sighting should be on anyone’s list when visiting New Zealand. Glow worms are New Zealand’s underground stars emitting a gorgeous blue-green glow. This natural beauty has been attracting tourists all over the world. And while they may be small, they will leave a spectacle like no other. To enjoy the glimmering world of glow worms, here are 5 hidden caves to spot them in New Zealand.

 

What Is A Glow Worm?

A glow worm is a crawling insect capable of emitting a prolonged or continuous glow of light. Their tails produce a glow because of bioluminescence. This is the reaction between the chemicals their bodies give off and the oxygen in the air. Glowworms emit light to attract food, burn off its waste, warn predators, or attract mates. What do glowworms grow into? While maggots grow into houseflies, glowworms grow into fungus gnats, which are like mosquitoes.

 

Glowworms are normally found in New Zealand and Australia populating cave ceilings. These cave bugs also inhabit undisturbed woodland areas where there’s an abundance of prey. Glowworms predominantly feed on snails and slugs. These make up the majority of their diet. They also eat smaller insects and small invertebrates.

When they’re hungry, their light shines brighter. The colors that glowworms emit include red, yellow, orange, blue, and green. With its high population, when shining together, glowworms can illuminate a cave.

When visiting glow worm caves in New Zealand, it’s important to observe proper etiquette. This is to ensure the comfort and safety of all the visitors. Aside from that, this is to ensure the protection of the glow worms and cave resources.

 

Here are some important etiquette tips to follow:

  • Listen to and follow the instructions: Keep in mind that you’re entering a sensitive environment so it’s important to follow the rules. If the cave rules say no food and drinks allowed, please respect that.

  • Be respectful to the guide and other visitors: Just as it’s important to follow the rules, it’s equally important to respect the guide and other visitors. Keep your voice low throughout the tour so everyone can understand the guide well. Maintain a harmonious and respectful atmosphere throughout the glow worm tour. 

  • No taking of photos: Photography is not allowed inside most of the glow worms caves in New Zealand. This is due to the sensitivity of the glow worms. Lights and flashes are harmful to the glowing nature of these bug caves. However, there are caves that allow non-flash photography and video. Make sure to clarify this before entering the cave.

  • No touching of anything: Don’t touch or move anything when inside the cave. These include rocks and the glow worms. Should there anything that needs to be moved, let your guide do it. 

  • No light-up shoes in the cave: Electronic gadgets are not allowed inside the caves. These also include light-up shoes or any other form of gadgets that light up. Flashlights are allowed but use them only when needed. Unnecessary light can easily disturb and harm glow worms.

  • No loud noises: Aside from light, loud sounds can disturb and harm glow worms. Refrain from making unnecessary loud sounds. This also means don’t bring music devices that can be disturbing throughout the tour. 

  • No littering: Just like in any other tour, don’t litter. Maintain cleanliness on the boat and the surroundings. Should you have any disposables, keep them in your bag first.

What Type Of Insect Is A Glow Worm?

Glow worms are often mistaken as worms, but they are actually not. Glow worms are adult beetles or their larvae. These cave bugs belong to the Lampyridae family. Currently, there are over 2,000 lampyrid species existing. 

 

What Does A Glow Worm Look Like?

Glowworms are narrow beetles with medium-sized bodies. The males are more beetle-looking, while the females look similar to the larvae as they don’t have wings. Glowworms mostly inhabit under rocks or limestones and feed on snails and slugs. 

 

What Makes Glow Worms Glow?

The glowworms in New Zealand are among the creatures that have the ability to produce light naturally. This process is called bioluminescence. It’s a result of a chemical reaction between some components from their bodies and the oxygen in the air. 

 

Why Do Glow Worms Glow?

Glowworms glow mainly as part of their hunting behavior. This light greatly attracts smaller insects that they feed on. The glow becomes even more attractive because glow worms live in dark places. 

 

Glowworms spin sticky threads that they use to hang from caves. This sticky thread eventually traps the smaller insects that get attracted by their glow. The excellent combination of their glow, sticky thread, and dark habitat makes glow worms successful hunters. 

 

How Was The Glow Worm Cave Formed?

Glow-worm caves form when the hard limestone under the ocean, through the years, move and rise above the seafloor. When these rocks are exposed to air, they will separate and create cracks, allowing water to flow in and dissolve the limestone. After many years, caves are formed. Insects are the common animals that live in these caves. Some of these include albino cave ants, giant crickets, and the glowworms as the most popular.
