Legionary Ant
The most common army ant species in the United States, conducting nocturnal column raids on other ant nests. Workers are small and reddish-brown with reduced eyes.
Did You Know?
They are rarely seen because they raid almost exclusively at night and spend most of their time underground.
Stripe-Backed Leafcutter Ant
A small leafcutter ant adapted to the grasslands and dry regions of southern South America. Unlike most leafcutter ants, it primarily harvests grass blades and herbaceous plant material. Nests are relatively small and partially surficial, often marked by a low mound of discarded plant material.
Did You Know?
It is one of the few leafcutter ants to thrive in temperate grasslands, tolerating winter temperatures that would kill most tropical species.
