How can you prevent ants from eating monarch caterpillars?

I haven't had a problem with ants but there are wasps that lay their eggs in the caterpillars. The wasp larva eat their way out, killing the monarch caterpillar. I frequently have this problem with the caterpillars of swallowtail butterflies.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
