Pheidole hoelldobleri

Longino (1997) states that hoelldobleri “occurs in wet forest habitats, either in the canopy of mature forest or in small trees of young second growth, where it nests opportunistically in cavities in live stems, and in the forks of small trees. It may use accretal soil as nest material.” He obtained specimens by fogging in the canopy of the forest of the La Selva Biological Station, as well as from guava (Psidium) and Cecropia trees along roads and in pastures.
