Monarch Butterflies are not poisonous, but they are toxic to predators due to the milkweed they consume during their larval stage. This toxicity comes from the cardenolides (or cardiac glycosides) in milkweed, which make them unpalatable to birds and other potential threats. While they are not harmful to humans, handling them may cause mild skin irritation in some cases.
