Parasitic zombie-ant fungus thrives in mosses, too

Scientists studying the parasitic Ophiocordyceps fungus, famous for hijacking the minds and bodies of insects, have discovered that the parasite also resides within nearby mosses.

DNA sequencing of samples collected from infected insects and vegetation in the Amazon basin revealed the presence of fungal material inside the moss tissue. This dual-lifestyle strategy suggests the fungus can survive inside plant hosts when insect populations are low, which may explain why dying host insects often bite directly into moss carpets during their final moments.

The research indicates that this parasitic relationship is more ecologically complex than previously assumed, pointing to a potential co-evolutionary bond between the fungus, the manipulated insect hosts, and the surrounding flora. Researchers gathered plant and insect specimens from Amazonian "ant graveyards" to confirm that the exact same fungal DNA exists in both the zombified insects and the specific vegetation they clamp onto before dying. This finding suggests the fungus may actively direct its hosts toward specific mossy environments to continue its lifecycle.
