The Monarch butterfly feeds as a larva on species of milkweeds. The milkweeds contain a group of chemicals called cardiac glycosides. Cardiac glycosides are poisonous to vertebrates. The larvae store these cardiac glycosides and the later adult Monarch butterfly contains them as well. If a bird (or other vertebrate such as a mouse or frog) eats a Monarch it finds them distasteful to begin with and is later sick.. Alisa Villarreal. Lily of the Valley. Introduction.
