larvae. Younger workers do receive sugary substances from older workers through trophallaxis. These older workers have the most diverse diet, consisting of sugary substances derived mostly from plants found from their foraging trips. Queens: Founding queens have a low level of fat reserves when compared to other genera. This is because they rely on their fungal gardens to provide these extra nutrients the first generation of workers will need. There is normally a monogynous colony structure within Cyphomyrmex. The queen’s diet is primarily mycophagous, however some sugars are fed to her from the older, foraging workers. Behavior The rimosus group is known for their cultivation of nodules of fungus, also called yeast gardens. This type of growth is known for clusters of small patches of fungus on irregularly shaped nodules full of single-celled yeast-like cells. This type of growth is unique in association with Cyphomyrmex ants. So, it is thought of as a form of domestication for Leucocoprineaceous fungi as they naturally grow in the mycelium form. Workers grow nodules of fungus, in the tribe Leucocoprineae, and they perform this in stages. First, workers will clean a portion of the ground and place insect feces, an old exoskeleton, or another organic item like a leaf. Then a worker will regurgitate fluids from her crop and add anal fluids. She then lets it dry on the surface. Other workers, or the same one, will repeat this process until the ball is about 0.8 mm. At this point, it is transplanted to where other nodules are growing with fungi. This new one is rubbed on established colonies and then placed on the ground, starting a new, small garden. Gardens can also be created hanging from roots on the ceiling of a nest, showing plasticity in the behavior of nest making. Workers also can have highly aggressive behavior towards unwanted guests. Specialized wasps in the family Diapriidae parasitize larvae and can induce a relatively large mortality rate, with about 16% of all larvae being infected. Any newly emerged wasps found in the brood piles are almost immediately attacked. Social chemistry Most Cyphomyrmex species are found to contain 3-octanol. This is thought to act as an alarm signal across species. Traces of nonanal are also found within the genus. Another common chemical group are farnesenes. It contributes to trail following behaviors, and ,potentially more importantly, influences agriculture practices. Some of the nodule-making species contain
