Natural History

Brown (1959) characterizes the genus as a whole as forming

"small colonies, chiefly in the leaf litter of rain forest or tropical evergreen forest, and nests occupy cavities in rotting twigs, pieces of bark or similar forest-floor vegetable debris... The food... consists primarily of small entomobryomorph Collembola and possibly some other minute terrestrial arthropods as well. Hunting behavior is like that of Smithistruma rather than like the Strumigenys so far studied."

Selected Records
