Bionomics

Pheidole inhabits various habitats such as open lands, grasslands, forest edges and well-developed forests. Their nests are usually found in rotting logs, twigs, wood fragments, under stones and in soil. The majority of species forage on the ground, but some such as P. vulgaris forage both on and under the ground.
