[1] Plagiolepis alluaudi is a very small ant averaging 1⁄16 of an inch (1.6 mm) in total length.

P. alluaudi is known to protect these insect species—which are often agricultural pests—from predators, going so far as to raise the pests' offspring in their nest until the larvae reach adulthood.

[2] Colonies of P. alluaudi contain thousands of egg-laying queen ants, forming supercolonies.

However, it can be a threat to agricultural crops, such as citrus, by protecting other insect species that transmit disease.

[3] Plagiolepis alluaudi is generally introduced on land to which they are not native via shipping lanes.
