Nests are found in a variety of arid or partly arid environments. Some species live in extremely hot deserts, others reside in transitional habitats, and still other species can be found in woodlands which are somewhat cool but still very dry for a large part of the year
Their role is to eat as much as possible of the food presented to them by workers. Their abdomens will swell enormously when food is stored there in the form of water, liquids and body fats. When food is otherwise scarce other ants extract nourishment from them by stroking the antennae of the Honeypot Ant, causing the Honeypot Ant to regurgitate the stored liquid
The abdomen of species like Camponotus inflatus consists of hard stiff plates connected by a softer, more flexible arthrodial membrane. When the abdomen is empty, the arthrodial membrane is folded and the sclerites overlap, but when the abdomen fills the arthrodial membrane becomes fully stretched, leaving the sclerites widely separated
They can live anywhere in the nest, but usually found deep underground, unable to move, swollen to the size of grapes
Honeypot Ants such as Melophorus Bagoti and Camponotus are edible and form an occasional part of the diet of various Indigenous Australians.
