'Exceptionally rare' pink grasshopper spotted by New Zealand ranger – video

Researchers from New Zealand's conservation department conducting an annual grasshopper survey near Lake Tekapo on the South Island have spotted a rare pink grasshopper. The species - the robust grasshopper - is native to New Zealand and is the country's largest lowland grasshopper. The pink hue is thought to be caused by a genetic mutation, as the insect is typically grey or brown like the river stones of its native habitat in the MacKenzie basin
