A previously unknown giant stick insect has been discovered in the high-altitude rainforests of Australia — and it may be the heaviest insect ever recorded in the country.
The colossal critter, which researchers named Acrophylla alta, grows to around 16 inches (40 centimeters) long. The giant insect lives in the difficult-to-access tree canopies of tropical North Queensland, which may be the reason it has eluded scientists for so long.
