Biology. The species was collected between 30–1732 m elevation, in Uapaca  woodland, montane rainforest, tropical dry forest, savanna and woodland, gallery forest and rainforest. Nests were located in rotten logs, in the soil, and under stones. Workers were collected from sifted litter.

Comments. Pheidole bessonii  is probably one of the most widespread Pheidole  species known from Madagascar. Morphologically it is most similar to P. voreios  and P. atsirakambiaty  , and its major workers can be separated from both species by punctate occipital lobes (which sometimes have additional thin and very sparse rugulae that arch posterolaterally), and sparsely rugocostulate lateral frons with distinctly punctate interspaces between rugocostulae. In contrast, majors of P. voreios  and P. atsirakambiaty  always have distinctly rugulate to costulate occipital lobes and frons. Minors of P. bessonii  can be separated from P. voreios  and P. atsirakambiaty  by the less elongated posterior part of the neck, a mostly smooth promesonotum with sparse microreticulae on its sides, and very small propodeal spines. Pheidole voreios  and P. atsirakambiaty  have a more elongated posterior part of the neck, mostly or entirely sculptured promesonotum, and larger propodeal spines. In addition, majors and minors of P. bessonii  can be distinguished from P. voreios  by the brown body.
