This video explains an interesting and complex pollination process involving insects and milkweed. Pollination in this common plant is very similar to the pollination of Orchids. The video is designed as a resource for teaching plant biology, particularly plant-insect relationships. Here a bee is trapped by the pollinia.

Take a microcosmic safari through a field of milkweed and discover a whole world of life, from bees to wasps to hummingbirds to butterflies. The charismatic Monarch butterfly is completely dependent on milkweed for its survival, and places like Yosemite National Park offer protection for this often overlooked plant.
