Hành vi xã hội

They have a powerful sting which they are not shy about using. Their sting is quite painful and best avoided. In the evening, a few Pogonomyrmex barbatus workers will usually seal the nest entrance with gravel and twigs to keep nighttime intruders out of the nest.

>Winged males and females swarm, pair and mate. Males soon die and females seek a suitable nesting site. After dropping her wings, the queen ant digs a burrow and produces a few eggs. Larvae hatch from eggs and developed through several stages (instars). Larvae are white and legless, shaped like a crookneck squash with a small distinct head. Pupation occurs within a cocoon. Worker ants produced by the queen ant begin caring for other developing ants, enlarge the nest and forage for food.
