Bumblebees fly by beating two pairs of wings. They make a buzzing sound when they fly.       Bumblebees live for one summer.               Bumblebees live in backyards and gardens. Look near flowers if you want to find one.               Bumblebees are about 3/4 inch to 1 1/4 inch long.       Dinner for a bumblebee is pollen and nectar. Both of these come from flowers. Pollen is usually yellow and sometimes bumblebees get it on their legs because they land inside the flower and walk around in there.
