Are there natural predators that kill monarch eggs, larvae, and adults?
Yes, learn more about monarch natural predators on the Monarch Lab website. The percentage of monarchs that survive from egg to adulthood is very low. Researchers agree that less than 10% of the eggs that are laid survive to become adult butterflies, and some feel that this number may be significantly under 10%. To account for low survival in the wild, female monarchs can lay 300-500 eggs in their lifetime.
