Argentine Ant

Forms massive supercolonies spanning thousands of kilometers. One supercolony stretches 6,000 km along the Mediterranean coast. Displaces native ant species worldwide.

💡

Did You Know?

Argentine ants have formed a global megacolony — ants from Japan, California, and Europe recognize each other as nestmates and will not fight, forming one worldwide supercolony.

Slave-Making Ant

A facultative slave-making ant that raids colonies of other Formica species to steal pupae. The stolen brood hatches and works for the slave-maker colony. Workers are reddish with darker heads and can also establish independent colonies.

💡

Did You Know?

Unlike obligate slave-makers, this species can survive without slaves, but raided colonies grow much faster.
