Large Insects


Whether you love insects or find them creepy, it’s easy to believe that man is the master over them. When you consider these giant bugs, though, your ideas about man’s strength might change.


Fun Facts

  • The largest insect ever to live was the extinct dragonfly-like insect belonging to the Protodonata This insect had an impressive wingspan of 2.5 feet and had huge mandibles (jaws). Now that’s something out of a horror show.
  • Insects, like everything else, tend to grow larger in warm, moist climates with ample food supplies. Many huge insects live in rainforests, including the titan beetle, which lives in the Amazon, and can grow to be 6.5 inches long – longer than your whole hand. This massive beetle has jaws strong enough to break a pencil in half.
  • On the island of New Zealand lives a cricket-like insect, the giant weta. At 2.5 ounces, it’s too heavy to fly, but scuttles on the ground. Its name comes from the Maori word wetapunga, or “God of the ugly things.”
  • Stick insects look like dried sticks and leaves – a clever camouflage that keeps these insects safe. The largest ones live in Southeast Asia and can grow to 2 feet or more. They look scary, but they’re actually so docile that they’re kept as pets.
  • The Goliath beetles of Africa can grow 4 inches long and weigh up to 3 ounces. They’re sometimes kept as pets and fed dog food or cat food.
