Winged queen weaver ant (Oecophylla smaradigna) from Cambodia.
A common sight among foraging leafcutter ants (Atta cephalotes) in Costa Rica is a smaller ant, known as the minima caste, riding on top of the foraged item being carried by a larger worker. While it might appear that they are simply hitching a free ride, in fact they are providing an important service - protecting their sisters from opportunistic parasitic flies (Phoridae) that attempt to deposit eggs on them.
Major and minor worker ants, genus Camponotus, feed on nectar in the botanical garden in Belize.
