Natural History
This species inhabits forest habitats in the Atlantic lowlands of Costa Rica. I know it from only a few collections. At Casa Plastico, a site above La Selva Biological Station at about 500m elevation, I observed a massive emergence from a nest. A tree was surrounded by a large Atta nest, and at the base of the tree a patch of leaf litter 30cm across was solidly covered with workers, males, alate queens, and brood of S. succinea. At La Selva I have collected the species twice. One collection was of workers scattered over the surface of a freshly sawn log, near the arboretum. The other was workers in suspended dead wood in forest near the lab clearing. Project ALAS never collected the species in any of the quantitative sampling programs (Berlese samples, Winkler, Malaise traps, canopy fogging). A worker has been collected in one of the Winkler samples of Conservation International's TEAM project.
