Crematogaster acuta

DaRocha et al. (2015) studied the diversity of ants found in bromeliads of a single large tree of Erythrina, a common cocoa shade tree, at an agricultural research center in Ilhéus, Brazil. Forty-seven species of ants were found in 36 of 52 the bromeliads examined. Bromeliads with suspended soil and those that were larger had higher ant diversity. Crematogaster acuta was found in 8 different bromeliads but was associated with twigs and bark cavities, rather than suspended soil or litter, of the plants.
