Biology
Kohout (1988) - A nest was located on the edge of the primary forest, some 1.5m above the ground. It measured approximately 20cm in diameter, and was constructed between twisting multi-stems of a woody liana and the adjacent tree trunk. Its walls incorporated the foliage and shoots of an abundant tendril climber. This nest followed the basic structural design observed in Polyrhachis erosispina throughout Papua New Guinea, and was typical in its situation in the lower arboreal zone. In areas with abundant bamboo growth erosispina, together with many other Polyrhachis species (of subgenera other than Polyrhachis), normally nests in bamboo internodes, much as was the case with the Polyrhachis taylori type colony.

Nests always contain one queen.
