Goliath Beetle (Goliathus) on hand

One of the largest insects on Earth with a heavy, bulky body, the Goliath beetles (named after the biblical giant Goliath) are members of subfamily Cetoniinae, within the family Scarabaeidae. They can be found in many of Africa’s tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. Goliath beetles measure from 60–110 millimetres (2.4–4.3 in) for males and 50–80 millimetres (2.0–3.1 in) for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark brown to silky white, but the males are normally brown/white/black or black/white.
