Pheidole aper

Rosumek (2017) assessed trophic resource use and period of activity within the ant community in a southern Brazil Atlantic forest. He found this species, relative to other Pheidole sampled in this study, used more "melezitose (a honeydew analog) over other resources. Since honeydew is the only reliable source of this sugar in nature, interaction with sap-sucking insects should be important for this species."
