It's not just bees that help flowers spread their pollen. Wind, other insects, bats and hummingbirds also drink the nectar of flowers and can spread pollen from flower to flower. There are two main types of pollination, wind and insect. Insects use their proboscis, that's a really long insect tongue, to get nectar from flowers. Nectar is a mixture of sucrose and water made by the glands of the flowers called nectaries at the base of petals. Film maker Louie Schwartzberg has made an amazing documentary with time lapse video capturing different animals and insects collecting pollen from flowers.
