plerergate
A plerergate is a polymorph of an ant, also known as a replete or ''rotund'', characterized by an enlarged abdominal area (the crop of the gullet) for the purpose of food storage and survival.〔(antbase.org )〕 This occurs in honey ants.
For example, the North American species ''Myrmecocystus mexicanus'' has select sterile workers act as plerergates or repletes during times of food scarcity. When the pleregates are fully engorged, they become immobile and hang from the ceilings of the underground nests. Other workers drain them of their liquid food stores to feed the rest of the colony.〔Conway, John R. "The Biology of Honey Ants."''The American Biology Teacher''. , Vol. 48, No. 6 (Sep., 1986), pp. 335–343.〕
