Monarch butterflies have been facing a rapid decline. In order to find ways to help, it's essential to first understand the life cycle of monarchs. When adult monarch butterflies migrate from their overwintering grounds in spring, the females begin a search for a suitable place to lay their eggs.
Female monarchs lay their eggs exclusively on milkweed plants, one of the critical roles it plays in monarch survival. Female monarchs will actually taste the leaf to make sure it's suitable milkweed, before laying her eggs.
