Ground Weta (Hemiandrus) – undescribed species

Ground Weta (Hemiandrus) – undescribed species

This New Zealand genus contains about 35 species, of which only some 15 appear to have been described so far, leaving about 20 species still undescribed. [1][3]

The ground weta are thought to be widespread and common, some are even found in urban gardens, however, some species of course are very restricted and are indeed threatened.

Some species are known to exhibit maternal care of eggs and offspring – the mothers take care for their eggs and their young. [2]

Hemideina broughi Buller

West Coast Bush Weta (Hemideina broughi)

The West Coast Bush Weta is an about 8,5 cm large, rather aggressive weta species.

The species is endemic to the northwest part of New Zealand’s South Island, where it can be found at elevations of up to 1100 m in old, and partly hollowed southern beeches, namely tawhai raunui (Fuscospora fusca (Hook. f.) Heenan & Smissen) resp. tawhai rauriki (Fuscospora cliffortioides (Hook. f.) Heenan & Smissen).
