Specimen Labels

Rosumek (2017) assessed trophic resource use and period of activity within the ant community in a southern Brazil Atlantic forest. He found, relative to other Pheidole sampled in this study, Pheidole lucretii, Pheidole nesiota, and Pheidole sigillata had similar patterns and broadly used the most attractive resources.
