Underground Army Ant

A mostly subterranean army ant that occasionally surfaces in massive raiding columns across the Americas. Workers are pale yellow, reflecting their underground lifestyle.

💡

Did You Know?

They are the most frequently encountered army ants in the Americas but are rarely seen because of their subterranean habits.

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.
