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.
Monarchs cannot survive without milkweed; their caterpillars only eat milkweed plants (Asclepias spp. ), and monarch butterflies need milkweed to lay their eggs. With shifting land management practices, we have lost much milkweed from the landscape.ow milkweed seeds by scattering them on the soil surface 1/4-1/2 inch apart, and then cover with about 1/4 inch of additional soil. Water frequently after planting until plants become established. Plugs can be placed directly into the ground.
