'Once the ant turned its back on the colony and walked away, it was on a death march. And the parasite was in the driver's seat'

The decapitating fly Pseudacteon wasmanni lays an egg inside an ant's thorax in less than a second .

Once the egg hatches, the ant has only a few weeks of life before it succumbs to the manipulations of its attacker.

Little is known about how the parasitoid avoids being destroyed by the ant's immune system.

Parasitoid insects keep their zombie host alive until the larva's metamorphosis is over, but phorids pupate unguarded inside their dead hosts' heads.

The exoskeleton of an ant's head is extremely hard — tougher than other parts of its body — lends extra protection to the pupating larva.

A few hours after emerging, the adult phorid fly is ready to mate and continue its reproductive cycle.
