Can Milkweed Beetles and Monarch Butterfly caterpillars coexist on milkweed plants?

Question

Each year it seems as though there are many more beetles and far fewer Monarch butterfly eggs.

This year there seems to to be an exponentially higher number of beetles. A few of the plants are turning yellow.

I would really appreciate and help on this.

Answer 1

They may coexist, with a decrease in their potential for growth.  For this to occur, they must partition the resource.
