For weeks, Huw and his crew search the jungle floor for a distressed bullet ant. Finally, they find their guy.
The ant is near death. Spores from a parasitic fungus have infiltrated its body and mind…driving it insane. As cameras roll, a parasite begins to grow from the insect's head. After three weeks, deadly spores will burst from the alien growth. "That was a sequence that I'm probably most proud of," Huw says.
When sick ants like this one are discovered in a colony, worker ants carry them far away and leave them to die. If they don't, thousands could suffer the same fate. Huw says he saw whole colonies destroyed by this fungus.
