Honeypot ant
Ants that store food in living workers
Honeypot ants, also called honey ants, are ants which have specialized workers—repletes, plerergates or rotunds—that consume large amounts of food to the point that their abdomens swell enormously. This phenomenon of extreme inflation of the trunk is called physogastry. Other ants then extract nourishment from them, through the process of trophallaxis.
