Named after the biblical giant slain by David, goliath beetles are among the largest insects on Earth. Native to Africa, they are found mostly in tropical forests, where they feed primarily on tree sap and fruit. Heavily armored, they measure from 2 to 4.3 inches (50–110 mm) long as adults and can reach weights of up 3.5 ounces (100 grams) in the larval stage, though adults are only about half this weight. How long do they live? Discuss
