This process takes 4–10 days. [9] Dead ants are found in areas termed "graveyards" which contain high densities of dead ants previously infected by the same fungus. [16] The term "zombie ants" has been used in popular media as well as scientific articles, but has also been described as "catchy, yet misleading." [17] [18]
The ant clamps its jaws around the plant in a "death grip" and following, mycelia grow from the ant's feet and stitch them to the surface of the plant. [9] The spores released from the ant carcass fall to the ground and infect other ants that come in contact with the spores so that this cycle continues. [ 10 ]
The fungus Escovopsis is a parasite in fungus-growing ant colonies that can greatly harm the fungal gardens through infection, [22] and the bacterium Pseudonocardia has a mutualistic relationship with ants. The relationship is thought to have been used by the ants for millions of years, co-evolving to produce the right type of antibiotics.
From mosquitoes, ants, flies, roaches and more, bugs are everywhere when it’s warm. This summer’s crop of creepy crawlers look ugly and sinister. But don’t be fooled by their sizes.
The scale of the farming done by fungus-farming ants can be compared to human's industrialized farming. [5] [11] [78] [79] A colony can "[defoliate] a mature eucalyptus tree overnight". [33] The cutting of leaves to grow fungus to feed millions of ants per colony has a large ecological impact in the subtropical areas in which they reside. [7]

The fungus needs the ants to stay alive, and the larvae need the fungus to stay alive, so mutualism is obligatory. The fungi used by the higher attine ants no longer produce spores. These ants fully domesticated their fungal partner 15 million years ago, a process that took 30 million years to complete. [13]
American entomologist and myrmecologist Neal A. Weber began publishing his research on ants in 1934 continued to investigate the relationship between ants and fungus gardens for 35 years. Little had been published in the twentieth century about the species Escovopsis and ant gardens prior to his 1966 article "Fungus-growing ants" in the journal ...
