It is also commonly called the ghost moth or pepetuna.
This moth is endemic to the North Island of New Zealand.
It is New Zealand’s largest moth, with a wingspan of up to 150 mm.
It spends the first five to six years of its life as a grub in a tree trunk (common host plants are the puriri tree (Vitex lucens) and putaputawētā (Carpodetus serratus), but puriri larva also inhabit non-native species such as Eucalyptus), with the last 48 hours of its life as a moth.
