Workers are the ubiquitous wingless ants that carry out the day-to-day tasks that keep the colony functioning. These usually non-reproductive females make up the vast majority of the colony's population, and are likely to be the only ants seen when observing a Pogo nest, or just about any ant colony (unless mating activity is occurring). Once the colony has been established, foraging, nest construction/maintenance, brood care, and defensive duties are all performed by these workers.

Only one North American Pogo (P. badius, the Florida harvester) possesses a polymorphic worker caste, where workers of significantly different size and proportion have evolved to efficiently perform specialized tasks.

In addition to the workers, there are the reproductive females, including the queen, and 'virgin queens' (those reproductive females who have not yet mated and started a colony of their own). These females are anatomically different from the workers, and possess wings which are shed after mating (a very small number of ant species have egg-laying workers called gamergates, but this is very rare). Males (also winged) are also present in small numbers - they await their chance to take part in a mating swarm, soon after which they usually die. These reproductive members of the colony generally remain in the nest interior, and are not likely to be observed unless a mating swarm is in progress, however, we occasionally get a glimpse of a male P. salinus in or around a nest entrance.

Images of male and reproductive female Pogos will be coming to this site in the future!
