How do bees and insects pollinate flowers?
This bumble bee is starting the pollination process without even realizing it! When bees land on a flower like this milkweed, its feet often slips into a little groove that holds pollen sacs. When the bee flies away it carries away this sac like a saddlebag stuck on its feet. When this bee lands on another flower looking for nectar, the "saddlebag" falls off, the pollen falls out of the sac, and pollination is underway!
