Melissotarsus may be the only lineage besides humans to raise other animals for meat. Here, workers tend to domesticated scale insects inside the nest galleries.

Some species of Cyphomyrmex fungus-growing ants are unusual in cultivating their fungus in yeast form. Rather than spongy white mycelia, the gardens of these ants are full of bite-sized white yeast globules.

An ambitious Cyphomyrmex forager carries a piece of insect frass back to the nest. These ants feed exclusively on a fungus that grows on the bits of detritus they gather.

Inside the spongy galleries of the fungus garden, Acromyrmex echinatior leafcutter workers display microbial white patches on their chests made of Actinomyces bacteria. The bacteria are thought to produce antibiotics protecting the ants' fungus garden from infection- a true example of pesticide use among agricultural insects.
