The diet of leaf-cutter ants is principally _______. a. leaves b. fungus c. saliva-coated leaves d. fungus-treated leaves. The diet of leaf-cutter ants is principally fungus.
Both leaf-cutter ants and their Trachymyrmex relatives cultivate a specialized fungus (white) in subterranean farms. Researchers found that the same type of fungal parasites attack the farms of both Trachymyrmex and their leaf-cutter relatives. Credit: S. Solomon/Rice University.
