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.
Mars Leafcutter Ant
A major leafcutter ant species found in Colombian and Panamanian tropical forests. It forms large colonies with millions of workers that maintain extensive underground fungus gardens. Workers show extreme polymorphism, with soldier heads being over five times the width of minor workers.
Did You Know?
The waste dumps of its colonies support unique microbial communities found nowhere else, essentially creating their own mini-ecosystem of decomposition.
