Monarch Butterfly larvae can only survive on the Milkweed family of plants. This includes Common Milkweed, Butterfly Milkweed and Swamp Milkweed, all found in High Park. DSV aka Pale Swallow-wort is similar in structure (see the pods) but when Monarch mistakenly lay eggs on them, the larvae die when they eat it. DSV is a major concern as it is extremely aggressive and will grow back multiple plants if some of the root is left behind when pulled.
