Biology
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.

Dambros et al. (2018) - Gnamptogenys moelleri  was collected via arboreal fogging in an inundated northern Pantanal (Mato Grasso, Brazil) cambarazal forest. The seasonally flooded forest was dominated by Vochysia divergens Pohl. (Vochysiaceae).
