Some interesting facts from; “Common Insects in NZ, by David Millar 1971”, the Ghost Moth is the largest native winged insect with a wing spread reaching 150mm (6”). The moths used to appear in great swarms but with the clearing of their habitat, numbers have greatly reduced. The Morepork favour them as a food source.
The caterpillar bores into the growing limbs of a number of trees, which includes our Grey Willows, covering the entrance hole with a fine silken camouflaged web. The caterpillar stage lasts for three years before emerging as a moth during September to November.

Ghost month caterpillar bore the holes which pupa to moths that feed the Moreporks. The holes left behind are a shelter for Weta. Weta are also a food source for Morepork.
