Labor Day Potpourri | Monarch Butterfly Monarch Butterflies are not as plentiful as they once were. They need milkweed plants to complete their life cycle. Unfortunately, the milkweed population has been decreasing for a number of years. Female monarchs only lay eggs on milkweed plants since monarch caterpillars only eat milkweed. The milkweed plant provides both food and shelter for a caterpillar. After emerging, the adult Monarch eats nectar from a variety of flowering plants.
