The life histories, behaviour, diet, habitat, and
diurnal activity patterns of two species of Snares Island
weta, Zealandrosandrus subantaraticus and Insulanovlectron
spinosum, are presented. The males and females of
Z. subantarcticus had 12 instars. The males of I. spinosum
had 9 instars while the females had 10 instars. Eclosion,
moulting, inter- and intraspecific interactions, oviposition,
and cannabalism are described. The diet of both species
included arthropods, plant material, and dead seabirds.
Descriptions of abdomina-femoral stridulatory apparatus for
both species are presented. Reproductive parameters and sex
ratio of both species were examined. Diurnal activity
patterns showed an increase in activity half an hour after
sunset and a decrease half an hour before sunrise for both
species. These species of weta from the Snares Island showed
similarities in aspects of their biologies to those of
mainland species
