Meranoplus is a genus of slow moving mid and small ants. These are typified by a hard and often spiny exoskeleton and long fine hairs. These hairs act a defense mechanism particularly against other ants. I call them the heart-butt ant from their heart shaped gaster similar to those of Crematogaster.

They are ground dwelling ants and are mainly scavengers feeding on dead arthropods and other small dead animals. They also frequent plants such as herbs and shrubs for nectar and honeydew.

This species had their nuptial flights in the early morning after dawn on a windless morning. They typically fly around 4 feet above ground level and the female will hover at a particular spot until she is mated.

Another special feature of this species is that they have a recess on each side of their head where they can withdraw their antennae. One or two sets of spine are on the back of the thorax on either side with a stubby spine on either side of the first thoracic segment (pronotum). When attack they will curl up their bodies.
