The granulate bladder grasshopper (Prostalia granulata) is an endangered insect last recorded by scientists in 1980.

(Photo: Adrian Armstrong)The most comprehensive global report on ecosystem health estimates that nearly one million species of life are now threatened with extinction, many within decades. Armstrong was delighted by his discovery, but notes that Umtamvuna Nature Reserve still faces several threats, including illegal livestock grazing, unauthorised burning and not enough funding. Another potential threat to the rediscovered grasshopper, he says, is the aerial drift of pesticides from neighbouring macadamia nut orchards.
