A single mature colony excavates over 40 tons of soil, creating underground chambers that improve soil aeration and drainage.

Vegetable Caterpillar

The host of this relationship is the caterpillar of the native moth Aenetus virescens, parasitized by the endemic Cordyceps fungus. The fungus invades and mummifies the caterpillar underground, then sends a fruiting body to the surface. It was known to Maori as awhato.
