This is the largest type of beetle that exists, and it actually is one of the largest insects in the world. They are native to the tropics of Africa and feed off the moist, rotting wood in the rainforests located there.Like all beetles, the Goliath beetle begins life as an egg, hatching into a larva. The larva mainly lives off dead trees and plants, and so it is considered very good for the environment, helping to clean up waste. After many months of eating and growing, the larva builds itself a cocoon, from which it emerges completely transformed into the Goliath beetle. Once a beetle, it doesn't have too long to live. Its primary focus in this stage is reproduction.These beetles have colorful markings on their shells, although they are mostly black and white. They also share some other features with all beetles, such as the elytra, which are the hard, shell-like wings that form a protective cover over a second set of wings-the actual wings the beetle uses to fly. A male Goliath beetle has a Y-shaped horn on the top of its head (used for grappling with other beetles), while the female has no horn. These insects also have a set of claws on each leg, which are incredibly powerful. These claws, known as tarsi, allow the beetle to cling firmly to tree bark.The cover image is from Cassell's Natural History. The cover font is Adobe ITC Garamond.
