Pheidole absurda excavates deep nests in soil. Colonies are granivorous and store seeds in special chambers. Creighton (1966) studied the habits of this species (as P. ridicula) in south Texas. It seems to prefer open areas and seasonal habitats; it is not a lowland rainforest ant. It may follow a pattern of being a widespread lowland ant in the northern part of the range, becoming a mid-elevation species at the southern limit of the range.
