More than thirty species of ant have a caste known as 'honeypot ants'. These essentially act as living pantries for other ants in the colony. They consume large quantities of food until the abdomen is incredibly engorged. When worker ants lack other food sources, honeypot ants simply regurgitate out nutrients for them to eat.
In some parts of the world, eating honeypot ants is viewed as a sweet delicacy.
