Aquatic Leafcutter Ant

In millions of years, leafcutter ants may have to move from the tropical rainforests they live today to a fully submerged environment where they would have to adapt to survive. Today, the ants live underground, feeding off leaves they collect. Their new colonies would have to be on top of the water and feed off things like algae and seagrass instead of leaves. To make colonies float, they would need to have new tool-like mandibles to compact and press algae to make floating colonies. They would also need new legs that are long and hydrophobic to walk on water, similar to water striders. Lastly, the coloring would change from being all dark to match tree trunks to being light on the bottom to match the sun from below and dark to match the floor of the water on the top to deter predators from both sides, similar to sharks.
