Many insects, notably honey bees and some wasps, collect and store liquid for use at a later date. However, these insects store their food within their nest or in combs.
Honey ants are unique in using their own bodies as living storage, but they have more function than just storing food.
Some worker ants turn into honeypots right from their emergence from pupa stage. The young ants stay in the nest, and the worker ants who collect honey, feed them.
As they feed more honey than they need, the surplus honey gets stored in their abdomen. As their abdomen expand, the ants lose their mobility.
Some store liquids, body fat, and water from insect prey brought to them by worker ants. They can later serve as a food source for their fellow ants when food is otherwise scarce.
In Australia, they are eaten mostly by indigenous people as sweets and are considered a delicacy.
