What are the enemies of the monarch butterfly? The biggest threat to the monarch butterfly are wasps, bees, frogs, and especially people. Insects like to eat the eggs of monarch butterflies.
Milkweeds are the required host plants for monarch butterfly caterpillars (female monarchs lay their eggs on milkweeds) and their flowers provide nectar for bees, butterflies, and other beneficial insects. By planting milkweed, you can provide habitat for monarchs and also attract and support pollinators.
