Followed infected ants in the field through the final hours of manipulation, recording where they went, when they bit, and the state of their bodies, and examined the mandibular muscles of ants fixed in the biting posture.
- Studied in
- Camponotus leonardi, Ophiocordyceps unilateralis
- Sample size
- infected ants observed and dissected in the field
Infected ants leave the canopy, descend to a consistent height and orientation, and bite into a leaf vein around solar noon, dying there. The mandibular muscles of biting ants show atrophy and fungal cells among the fibres, and the bite becomes locked so the body remains attached after death.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
The manipulation is precise in place and time, and the locked bite is achieved through changes in the muscles operating the mandibles.
How NatureHQ reads it
The record that establishes how specific the manipulation is — a consistent height, a consistent orientation, a consistent time of day. That precision is what makes the case interesting, and it also raises the question the next study answered: precise control implies something doing the controlling, and where it is turned out not to be where everyone assumed.
- Field observation of a small number of individuals in the final stage of infection.
- One host–parasite pairing; Ophiocordyceps species are highly host-specific and differ.
