Natural History

Acropyga smithii is known to inhabit rainforests and cacao plantations. It occurs in the soil and litter; Weber (1944) reported nests from red clay soils down to a depth of 7.5 cm. Queens have been recorded from under the bark of a rotten log. Weber (1944) reported that at least two queens were found in one nest, indicating that this species may be polygynous. Winged reproductives have been collected from January-May.
