Glowworm, an exclusive specie from New Zealand
Only in New Zealand, Waitomo caves you will be able to experience this natural phenomenon of thousands of blue lights shining above your head. Glowworm also called Arachnocampa Luminosa or New Zealand glowworm. It is a species of fungus gnat that originates in New Zealand. Its structure and purpose are in some ways similar to a spider’s net. The fungus gnat egg hatches all over the cave walls and ceiling, the larva creates a long straw of mucus. It may move around the surface to find the best spot to create her silk nest.
The larva spins a net out of silk strings on the ceiling and then hangs down around 30 threads. Then it frequently places small glue drops all along those threads. The glue is made of 99 parts of water, so to survive glowworm needs humidity. Once the arrival of tourists caused a temperature change and humidity drop in the caves, as a consequence glowworms disappeared and did not return for approximately 50 years, they are back now, so make sure to visit it!
The glowworm illuminates its net of reflective droplets to attract its prey. Its victim mostly consists of mayflies and other small insects, however, it may trap spiders as well. When pray is stuck in the glue, the larva pulls it up and begins to ingest its victim alive. Each string can hold more or less three mayflies before it cracks, which prevents the net from falling down.
