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.

Dorymyrmex reginicula (at left), a socially parasitic species, is harassed by a worker of its host Dorymyrmex elegans.  Workers of the two species coexist in a single nest for a period after the parasite queen has assumed reproduction and before the last remaining host workers die off.  The transition period is not entirely smooth, as evidenced by this aggressive interaction.
