Which large African rainforest beetle is named after the biblical giant Goliath?

The large African rainforest beetle named after the biblical giant Goliath is the Goliath beetle.

Goliath beetles are several species in the genus Goliathus, found in tropical Africa. They are among the largest and heaviest living beetles, with striking black-and-white or brown-and-white patterns. Males often have a prominent Y-shaped horn on the head, which they use in contests with other males.

Adults commonly feed on tree sap and fruit, while larvae develop in decaying wood or rich organic material. Their substantial size comes from a life cycle supported by the abundant plant matter of tropical forests.

The name is sometimes confused with Hercules beetle, another very large scarab beetle from the Americas. Hercules beetles belong to the genus Dynastes; Goliath beetles belong to Goliathus. Both are famous giants, but they are not the same insect.
