How do ants

build their nest?

Ants live in the forest but how do they build their richly combed nests? They mince wood very finely, soak it in sweet honeydew that is excreted by aphids and let a fungus do the rest of the work: the fungus grows through the sweet substrate and gives the chambers strength, like steel in reinforced concrete. If a young queen flies on a wedding flight, she takes the fungus for a future nest with her.

Picture above: The shining-black wood ant can’t form a nest by herself, but sneaks into a nest of yellow Chthonolasius ants, kills their queen, and is supported by the workers in raising her own brood. © Schlick-Steiner & Steiner

Terrariums for

fungi-breeding ants

Project description

Fungi-breeding ants and termites are known from the tropics, but there are also native ant species that maintain a close symbiosis with fungi and cultivate mushroom gardens, which is largely unknown. This should change with the ant terraria.
