Some fun GlowWorm facts for you to amaze the kids next time you go:
- they're not really a worm, but the larval stage of a flying insect called a Fungus Gnat
- the scientific name is Arachnocampa luminosa, which means (broadly) "Glowing Spider Worm"
- each GlowWorm has 30-50 sticky threads that hang down which are literally used as fishing lines. Other flying insects are attracted to the light and get stuck in the threads
- the glow is produced by a chemical reaction between an enzyme called luciferase and a substrate called luciferin. These are produced by the GlowWorms and stored in a little sac right at the back end of their body
- there are 8-10 different species of GlowWorm found in NZ and Australia, but A. luminosa is unique to NZ
