Goliath beetle

Based on weight and bulk, goliath beetles are strong contenders for the title of largest insects on Earth.

Native to Africa, males of these species can grow to over 4 inches, and can weigh as much as 100 grams (3.5 ounces) in their larval stage.

Though they are believed to be primarily vegetarian in the wild, they have shown a voracious appetite for protein in captivity, and captive beetles are often fed dog and cat food.
