Habitat/Ecology. This species was found in disturbed mature or young secondary forest fragments in semi-urban settings, including abandoned plantation secondary forest. Workers and queens were collected mainly from leaf litter or ground debris; multiple alate queens were also collected via malaise traps.

Remarks. An introduced species native to the Neotropical region, S. eggersi has been reported to be an unusually resilient species tolerant of relatively dry environments, and adaptable to a broad range of habitats including highly disturbed forests (Deyrup 1997; Wang & Yamane 2017).
