Natural History:

Brown and Wilson (1959) summarize the genus as follows:

"Widespread in tropics and warm temperate areas. Primarily forest-dwelling; some species occur in grassland and arid scrub. ... Nests mostly in soil and rotting wood; a few species live in arboreal plant cavities in tropical rain forest. Foraging hypogaeic to epigaeic-arboreal. Food: most species are collembolan feeders; a few are polyphagous predators or occasionally feed on sugary substances..."

Members of the genus are all predaceous, with a kinetic mode of attack (Bolton 1999).

The feeding habits of louisianae have been studied by Wilson (1950, 1954) and Brown (1962). Workers take live prey, mostly small arthropods in litter and soil. Preferred prey are entomobryoid and symphypleonan Collembola; poduroid collembolans are not taken.

The species prefers synanthropic and/or seasonally dry habitats. It is more abundant in the peripheral parts of its range (Costa Rica northward, southern Brazil southward) than in the center (Panama southward to Amazonian Brazil) (Brown 1961).
