Grass Grub Beetle

Costelytra zealandica (commonly known as the grass grub) is a species of scarab beetle found in forested areas of greater Wellington. It was originally described in 1846 by the British entomologist Adam White as Rhisotrogus zealandicus from a specimen obtained during the Ross expedition. The species is known to feed on roots of plants and trees, so is considered a pest for many farm pastures.
