Caterpillar Almost Forces Itself Down Frog's Throat

I've heard of parasites that get into ants or snails and make them climb to the tip of grass blades or plants, which gets them eaten by birds or other predators which incubate the offspring of the parasites in their bodies and then excrete them where ants or snails will then get infected. They call them Zombie Parasites I think. In fact, I may have learned of this right here at Neatorama.

This behavior looks exactly like that to me, but if a parasite can 'sense' a predator from inside the host I am at the same time impressed and really really scared.

Any Neato-Biologists or Neato-Zoologists care to comment on this?

Notice how the frog blinks and retracts his eyeballs into his head when he finally gulps the caterpillar? He does that to help him shove the food down his throat. I'm glad humans don't have to do that when we swallow.
