The largest insect on Earth: The Goliath beetle (Goliathus regius) (10 Pics)

Compartir

The Goliath beetles (named after the biblical giant Goliath) are among the largest insects on Earth, if measured in terms of size, bulk and weight. 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.

Apart from their massive size, Goliathus beetles are strikingly patterned as well. Prominent markings common to all of the Goliathus species are the sharply contrasting black vertical stripes on the pronotum (thoracic shield).
