How big is the biggest insect on Earth?

Phryganistria chinensis Zhao is a stick insect or walking stick, and it is the biggest insect in the world. It was discovered in China three years ago and is over 2 feet long (24.5 inches), which surpasses the size of the previous record holder— a walking stick of the Phobaeticus chani species of Malaysia— by 2.3 inches. The walking sticks only eat plants. They protect themselves from predators by visually merging into their surroundings: They camouflage themselves as dead branches thanks to their body shape and coloration.
