Fiordland Cave Weta
A large cave weta found in the cave systems of the Waitomo region in New Zealand. It has very long legs and antennae adapted to navigating dark cave environments. These weta form an important part of cave ecosystems, connecting surface and underground food webs.

Cave weta venture outside caves at night to feed, then return and deposit their droppings inside, providing an essential nutrient input for the entire cave ecosystem.
Trechine Cave Ground Beetle
A fully cave-adapted ground beetle from the Pyrenees with no eyes, no pigmentation, and extremely elongated spider-like legs and antennae. It is beautifully adapted to life in total darkness.
Did You Know?
Named after Cerberus, the three-headed guard dog of the underworld, this beetle navigates pitch-dark caves using enormously elongated antennae that can be twice its body length.
