The Green Rock-hopper grasshopper, Brachaspis collinus is an alpine species of short-horned grasshopper in the family Acrididae. It is found in New Zealand in the mountains of northern South Island, above the tree line and as high as 2000 m asl.[1][2][3][4] In New Zealand alpine grasshoppers can freeze solid at any time of the year and are alive when they thaw out when temperatures rise.[5]
Brachaspis collinus is flightless and adults are relative large (females 32 mm),[1] and common amongst scree and tussock.[6] Although widespread in 2020, about 97% of the habitat of the green rock-hopper grasshopper will be lost due to global warming by 2070.[7] The species is variable in colour; most individuals are green with yellow markings, but some are olive-grey. In the Kaikoura ranges (Mt Luxford) B. collinus hybridises with B. nivalis,[8] but elsewhere the two species are well differentiated.[4]
An endemic species of mite (Erythrites jacksoni) is an ectoparasite of this grasshopper.[9]
