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).
rogeri is native to Africa but has spread, along with human commerce, to many parts of the globe. It occurs in Hawaii, Fiji, greenhouses in England and Scotland, Florida, and many islands in the Caribbean. In the mainland Neotropics, I know of records from Guyana and the ones reported here for Costa Rica. Nests are in and under dead wood on the ground. Workers preferentially prey on entomobryoid Collembola and Campodeidae, but also take a variety of other small arthropods (Brown 1954).
At La Selva Biological Station, rogeri occurs in leaf litter deep within mature rainforest. Thus, it appears to be one of the few exotics that can invade mature forest, rather than being restricted to synanthropic habitats.
