I am posting this photo to illustrate two things, how milkweeds are pollinated, and how insects sometimes get fatally caught in the flowers. YOu can see the pollen pads on this beetle's feet. When an insect lands on a milkweed flower head, its feet sink into the individual florets and attach to the pollen pads (or packets). When the insect flies off, the pollen pads go with them and when it lands on another plant, the pads attach to the next flower. However, sometimes insects cannot extricate themselves and they die on the flowers, unable to fly away.
