New Zealand is home to some of the world’s most charming natural phenomena, and among them is the mesmerizing glow of the Arachnocampa luminosa, or the New Zealand glowworm. These bioluminescent creatures transform dark, damp environments into otherworldly landscapes, captivating all who venture into their glowing domain. So, what are they? How do they glow? And what’s the best place to see glowworms in New Zealand?
What is Arachnocampa Luminosa?
None of the world’s glowworms are true worms. In the northern hemisphere, the name is used for beetles that fly around at night with their tail-lights flashing. In New Zealand and Australia, glow-worms are the larvae (maggots) of a special kind of fly known as a fungus gnat.
Fungus gnats look rather like mosquitoes, and most feed on mushrooms and other fungi. However, a small group of fungus gnats are carnivores, and the worm-like larvae of these species use their glowing lights to attract small flying insects into a snare of sticky threads. One species, Arachnocampa luminosa, is found throughout New Zealand, and others occur in Australia.
Hundreds of Arachnocampa larvae may live side by side in damp places, where the air is humid and still, to construct their snares. Caves and old mining tunnels are ideal. In the forest, glowworm snares are most common on moist banks beside a stream or in a ravine.
In caves, the insects light up at any time of the day or night. Outdoor glowworms start glowing shortly after dark and usually shine all night. Sometimes when a glowworm is disturbed, its light seems to go off suddenly. This is the larva slithering into a crevice, hiding from its light. It takes several minutes for the larvae to shut off the light.
Glowworm life cycle: A glowworm has four stages within its life cycle and has very short lifespans once they reach adulthood – a female glowworm will live up to 76 hours, whilst a male glowworm tends to survive up to 96 hours. All four stages of a glowworm’s life cycle take roughly 10-11 months to complete. It is easy to find glowworms at any time of year, however, a large number of eggs hatch into larvae during winter months. Their lights resemble a star-filled night sky. Māori call them titiwai, which refers to lights reflected in water.
How to Behave Around Glowworms During Your Visit
To “deal with” glowworms when observing them in their natural habitat, it’s important to minimize your impact on their delicate environment. This includes doing the following:
- Glowworms are highly sensitive to light, and a bright torch can cause them to stop glowing temporarily. It’s best to avoid shining bright lights pointed directly at them, taking into consideration that red light is less disruptive to their bioluminescence, so if you need to use a torch, try to keep the light directed away from the glowworms or use a red filter.
- Glowworm habitats are delicate ecosystems, and it’s important to minimize any disturbance, so please tiptoe and avoid making noise with your footsteps or touching the walls of caves, as this can disrupt the delicate structures the glowworms use to catch prey. Be aware that loud noises can affect the glowworms and other cave inhabitants.
- The best way to observe glowworms is in total darkness, as their glow is most noticeable in the absence of other light sources.
