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.
The Monarch knows instinctively where to go and how to get there. It is still a mystery exactly how this information is passed on. Monarchs live in all states and reproduce wherever they can find enough Milkweed to support their young. Monarchs are not pests and will not eat anything but Milkweed. They do not hurt crops, ornamental trees or in any way upset the balance of Nature in areas they are introduced. Monarchs are the State Butterfly of Alabama, Idaho, Illinois, Texas, West Virginia and Minnesota.
