Monarch butterflies lay their eggs on milkweed plants. The milkweed plant is the only food source for monarch caterpillars, so this is where the female butterflies choose to lay their eggs.
Yes, milkweed plants are the only food source for monarch caterpillars. The caterpillars rely on milkweed to lay eggs and feed their young. In return, monarch caterpillars help pollinate milkweed plants as they move from flower to flower.
Milkweed is important to butterflies because it is the host plant for monarch butterfly caterpillars. Monarch butterflies lay their eggs exclusively on milkweed plants, and the caterpillars feed on the leaves of milkweed as they grow and develop. Without milkweed, monarch butterflies would not be able to complete their life cycle.
Milkweed is crucial for butterflies, especially monarchs, as their larvae feed exclusively on milkweed leaves. Monarchs lay their eggs on milkweed plants, which provide necessary nutrients and chemicals that help protect the caterpillars from predators. Without milkweed, monarch populations can decline due to lack of suitable habitat for reproduction.
What plants Monarch butterflies do not like is not all that important, though no specific plants that they do not like are known. The most important thing is that they not only like, but need specific kinds of milkweed for their survival. They lay their eggs on milkweed and the caterpillars feed on the plant.
A monarch caterpillar will look for milk weed, once it finds one it will eat from it. That's how they get their poison. When they come out of their chrysalis they will fly around and every once in a while land on a milk eed and possibly spend a few minutes to a few hours on it. Monarch butterflies will eat milk weed too.

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.
Thanks to Monsanto and their product Round Up, milkweed are a lot more rare than they used to be. Many garden clubs are planting milkweed to help keep the monarch butterflies who have caterpillars that only live on milkweed.
