  Mississippi Gate-keeper Ant

  Colobopsis mississippiensis is a species of ant in the genus Colobopsis, first described by Smith in 1923. It belongs to a group of ants commonly known as "gate-keeper ants" or "doorkeeper ants," characterized by specialized major workers with enlarged, plug-shaped heads used to block nest entrances. The species is native to North America, with records from the Mississippi region implied by its specific epithet. Like other members of the Colobopsis cylindrica group, it exhibits caste polymorphism with distinct worker morphologies adapted for different colony functions.
