Milkweed is famous for being a virtual cafeteria for a large number of insects to feast upon.

Aphids are also found on milkweed, and tend to feed in large groups on the leaves and stems. The blue milkweed beetle feeds on milkweed and can be responsible for holes in leaves.

Do Monarch Butterflies live in Swan Plants?

The monarch butterfly must lay their eggs on milkweed plants (Asclepias ), and the swan plant is listed on wikipedia as a type of milkweed. Most plants in the milkweed family produce flowers which the monarch can feed on. The caterpillars of the monarch butterfly can only eat leaves from plants in the milkweed family and will die without this food source. The milkweed plant is known for it's white milky sap, which contains alkaloids, latex, and several other complex compounds including cardenolides. Some species are known to be toxic. The caterpillars are immune to the milkweed sap and actually make themselves poisonous by eating it. The butterfly retains the milkweed poison as a defense against predators. Both the monarch caterpillars and the monarch butterflies use bright color patterns as a warning that they are dangerous to eat.
