Iridomyrmex discors

Meaning of name: Unknown.

Distribution: This species has been found across most of Australia.

Remarks: Iridomyrmex ants are generally aggressive to other ants. They form large nests (from several hundred to over 300,000 workers), which limits the number of competing nests that can be formed in a given area. Iridomyrmex ants are generally scavengers.

These ants were approximately 10 millimetres long.
