What animal eat monarch butterflies?

Monarch Butterflies are primarily preyed upon by birds, especially those that are not deterred by their toxic nature. Some common predators include blue jays, robins, and other Songbirds that can consume them despite their toxicity from the milkweed plants they ingest. Additionally, certain insects like Spiders and wasps may also prey on monarchs. However, the bright coloration of monarchs serves as a warning to many potential predators about their unpalatable taste.
