Nest densities at La Selva, Costa Rica were high (7.48 nests/m2) and potential nest sites were abundant. Colonies moved frequently (residence times for species ranged from 35-146 days) from one twig nest to another, occupying a wide range of twig types. Colonization was not reduced by the presence of resident ant colonies. Queenright nests (in which at least one queen is present) and queenless workers, as well as dealate queens, colonized artificial nests. Activity times and diet composition did not differ between the two species with largest sample sizes; workers were active under most conditions. Despite their abundance, twig-dwelling ants are limited neither by availability of nest sites nor food. Many of the 32 species found coexisting at La Selva may be limited by high mortality during alate dispersal or colony movement. -from Author
