Parasite or Parasitoid

Here are some things that I learned today. A parasite is an organism that lives at the expense of its host which it doesn’t usually kill. A parasitoid kills its host. If you are a parasitoid, would you rather lay your eggs in a caterpillar that is well defended i.e. uses camouflage, has a covering that repels predators, or uses other defenses? Or would you prefer a caterpillar that isn’t well defended? Back up your answer.
