Goliathus goliatus is one of the largest species in the genus Goliathus, males having a body length of 50–110 millimetres (2.0–4.3 in) and females having a body length of 54–80 millimetres (2.1–3.1 in).
In addition to their massive size, Goliath beetles are strikingly patterned; prominent markings common to all of the Goliathus species are the sharply contrasting black vertical stripes on the pronotum (thoracic shield), while the various species may be most reliably distinguished based on their distinctive mix of elytral colors and patterns.

Müller's explanation of the mechanism for this was one of the first uses of mathematics in biology. He argued that a predator, such as a young bird, must attack at least one insect, say a wasp, to learn that the black and yellow colours mean a stinging insect. If bees were differently coloured, the young bird would have to attack one of them also.
Goliathus regius is very similar to Goliathus goliatus in both structure and colour characters. [4] It is one of the largest species of the genus Goliathus, with a body length of 50–115 millimetres (2.0–4.5 in) in males and of 56–82 millimetres (2.2–3.2 in) in females.
