Ants are incredible. The variety is absolutely enormous, in Panama in an apartment building on the 8th floor I stayed in for a while there were ants so small you could barely see them with the naked eye, and down on the ground right in front of the building were ants that were 10mm+.

The leafcutter ant paths there would look like conveyor belts running back and forth with slices of leaves from bushes, I could watch them for hours.
