One of the Most Surprisingly Impressive Natural Attractions in the World
One relatively lesser-known natural attraction that often surprises and delights visitors is the Waitomo Glowworm Caves in New Zealand. The caves are located in the North Island of New Zealand and are renowned for their unique phenomenon of glowworms illuminating the darkness. Inside the Waitomo Caves, you’ll find thousands of tiny glowworms called Arachnocampa luminosa. These bioluminescent…

In the humid cave, the insects use bioluminescent light and silk threads covered in sticky, reflective droplets to attract and capture prey

Glow Up with the New Zealand Glow Worm
Not technically a worm, the New Zealand Glow worm, or titiwai (Arachnocampa luminosa), is a species of fungus gnat found only in New Zealand. The distinctive larvae are only found in caves, particularly those with pools of water, while adults are more commonly found near the entrance of the caves in open, brush areas and wetlands; anywhere dim and moist.
The New Zealand glow worm begins its life as one of about a hundred eggs in a clutch. They hatch about 20 days after being laid and emerge in their larval form, between 3-5 mm (0.11-0.19 in) long. They immedietly begin to build 'nests' on the cave wall or roof. These nests are made of dozens of droplets of mucus strung together into long, sticky strands. The titiwai worm then produces a series of bioluminescent chemicals in its rear end. The lights, refracted off the strings of mucus, attract insects including adults of their own species and ensnares them for the glow worm to haul in and eat.
Individuals spend 6-12 months this way, growing until they're about 30-40mm (1.19-1.57 in). They then pupate for a period of several weeks, and females continue to emit light. This attracts males, who wait on the pupa for the female to emerge. Pupation takes several weeks and usually ends in the winter, when they emerge as sexually mature adults. The adult form is about 17 mm (0.66 in) long and resembles mosquitoes, with a dark, thin body. Their last 3 or 4 days are spent mating and, in the case of females, laying eggs. Most adults are eaten by predators like spiders, wasps, birds, bats, and larval A. luminosa, and those that don't eventually starve to death.
Conservation status: The IUCN has not rated A. luminosa, and no data is available on their populations. However, much of their habitats are protected as past of parks and tourist destinations.

[ID: two photos, one of a river flowing into a cave entrance, and the other of glow worms lighting up a cave ceiling. End ID]
I pulled an Emry Karic and took a boat through a glow-worm cave today!!!
Real glow-worms may not create patterns in reaction to music, like in The Stray Spirit, but they DO react to sound! If you make a loud noise, they’ll glow brighter for a few minutes.
Honestly, the glow-worms didn’t feel real. I kept thinking I was on a theme park ride or something! Truly amazing. There was a lot of internal screaming happening.
