Life Cycle and Behavior

Reproductive cycle

The reproductive cycle of Aphaenogaster tennesseensis is a fascinating process that plays a crucial role in the survival and expansion of the species. This ant species exhibits a unique reproductive strategy known as polygyny, where a single colony can have multiple queens. The reproductive cycle begins with the mating flight, during which the winged reproductive ants, both males and females, take to the air to find mates from other colonies. Once the mating is complete, the males die, and the fertilized queens return to the ground to establish new colonies. The queens shed their wings and excavate a small chamber in the soil, where they lay their eggs and care for the brood. The eggs hatch into larvae, which are fed and nurtured by the queens until they pupate and eventually emerge as adult worker ants. This reproductive cycle ensures the genetic diversity and resilience of Aphaenogaster tennesseensis, allowing the species to thrive in a variety of habitats and environments.

Foraging behavior

The foraging behavior of Aphaenogaster tennesseensis is an intriguing aspect of their ecology.
