About the Sigaus australis
Sigaus australis is the most common alpine grasshopper found in New Zealand. It can be found in the southern half of the South Island above the tree line. Sigaus australis was described in 1897 by Frederick Hutton. Like all of New Zealand sub-alpine and alpine grasshoppers S. australis has a 2 or 3 years life cycle. Individuals can survive the cold by freezing solid at any life stage, at any time of the year. Sigaus australis adults are relatively large grasshoppers (females ~ 26mm, 0.8g). The genus Sigaus is endemic to New Zealand.
Sigaus australis can be found in the southern half of the South Island, from Otago and Canterbury regions. It can be found as far south as the Takitimu Mountains and as far north as the Torless Range (43°14′39″S 171°48′34″E). Sigaus australis prefer tussock grasslands between 1,300–1,700 metres (4,300–5,600 ft) elevation, however, can be found as low as 200 metres (660 ft) on the Alexandra Tailings, (45°14′49″S 169°22′07″E) and as high as 2,000 metres (6,600 ft) on Smite Peak (43°21′10″S 171°14′17″E). Evidence from mtDNA sequencing suggests that S. australis encompasses several narrow endemic taxa and one widespread species... Wikipedia →
