Is Te Anau Glowworm Caves happening right now?
As of today, in season now. Earth Exhibit tracks the live conditions and flags it the moment it is on.
The Te Anau Glowworm Caves host dense colonies of Arachnocampa luminosa, bioluminescent fly larvae that hang silk threads tipped with sticky droplets to trap prey and emit a blue-green glow.
The effect is visible year-round on guided, low-light cave boat tours that cross Lake Te Anau and enter the protected cave system.
