Foraging activity of Pachycondyla striata and Ectatomma quadridens were studied in Rio Claro, SP, Brazil. Both the species are generalist predators. The daily hunting activities of both species were antagonic in relation to number of foragers leaving the nest, temperature and relative humidity: P. striata prefered the coolest and the wettest hours of the day, and E. quadridens prefered the warmest and the dryest hours of the day. Keywords: Ant, Ectatomma, foraging, Pachycondyla, Ponerinae.
