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.
Milkweed plants (Asclepias) are the host plants for Monarch butterflies...but milkweed is also a highly sought nectar source for many other butterfly species! Aside from attracting Monarch butterflies for egg-laying, milkweed entices swallowtails, painted ladies, American ladies, red admirals, fritillaries, and hairstreaks for nectaring.
