Summit Disease Explained
- Summit disease is when parasites drive insects to climb high and die in positions that maximize transmission to others below.
- This strategy appears across fungi and viruses and repeatedly evolves because it effectively spreads infectious particles.
Dantial's Drunk Walk To Death
- Kelly narrates the infected ant's progression: it picks up a spore, returns to the nest, then later leaves and performs a 'drunk walk' down and back up a stalk to die biting a leaf underside.
- The fungus then produces a stalk from the ant and rains spores down to infect new foragers.
Specialized Fungi, Precise Behaviors
- Ophiocordyceps unilateralis and close relatives are highly host-specific and produce very precise manipulated behaviors tuned to each ant species and environment.
- The manipulation details vary worldwide, but the core summit-and-bite pattern recurs across species.
