alexwild > Paratrechina longicornis - black crazy ant. Along a sun-soaked beach on a Panamanian island, ants drink from nectaries on the underside of a leaf. Many plants attract ants with nectaries, and the ants in return help remove the plant's herbivorous pests. Isla Contadora, Panama

alexwild > Formica obscuripes nestmate workers engaging in trophallaxis, or the social sharing of liquid food. This behavior does more than merely transfer food. Ants also use it to pass chemical signals among each other, and research has shown that trophallaxis helps the colony maintain a cohesive identifying odor. Wisconsin, USA
