'Arachnocampa luminosa' - this glow worm is unique to New Zealand and requires a special habitat to survive. There are numerous sites to view glow worms, many just a few steps from the homestead. The New Zealand glow worm is one of many creatures that naturally produce light (bioluminescence). The light is the result of a chemical reaction that involves several components: luciferin, a waste product; luciferase, the enzyme that acts upon luciferin; ATP, adenosine triphosphate, the energy molecule; and oxygen. These combined form an electronically excited product capable of emitting a blue-green light. The light is used to attract insects, brought into the cave in the rivers, which the glow worm catches and eats. If a glow-worm is hungry its light will shine a little brighter and is even more effective. When the female glow worm reaches the adult stage the light is used to attract males for mating.


Glowworms can be found in many areas around the farm
