Swollen-thorn Acacia Ant
An obligate acacia-ant mutualist that nests exclusively within the hollow thorns of Vachellia trees. Workers patrol the tree constantly, stinging any animal that contacts it.
Did You Know?
Acacia trees with these ant colonies grow significantly faster than uncolonized trees due to the ant's protection services.
Spine-waisted Ant
A slender reddish-brown ant common in eastern North American deciduous forests. It is an important seed disperser, carrying seeds with nutritious elaiosomes back to its nest.
Did You Know?
They are responsible for dispersing seeds of many spring wildflowers including trilliums, violets, and bloodroot.
