FACT #5 — Leafcutter ants are fungus farmers (seriously)

Leafcutter ants don’t cut leaves because they love salad. They cut leaves to feed a fungus they grow underground—because the fungus is the real food source for the colony. If you’ve ever seen a line of ants carrying leaf pieces like green flags, you’re basically watching an underground farm getting stocked up. https://asm.org/articles/2017/september/the-leaf-cutter-ant-s-50-million-years-of-farming

The fungus they raise is commonly called Leucoagaricus gongylophorus (you’ll also see it discussed under closely related names in the scientific literature). The fungus makes tiny nutrient-packed “food pods” called gongylidia, and the ants harvest those to feed the colony (especially the larvae). That’s the trade: ants bring plant material, the fungus turns it into usable nutrients.
