Bees are excellent pollinators because they have the ability to carry pollen in a specialized structure called a pollen basket or corbicula, located on their hind legs. As they move from flower to flower collecting nectar, they inadvertently pick up and transfer pollen grains from the male parts of one flower to the female parts of another. This leads to fertilization and the production of seeds and fruits. Bees are especially important for the pollination of crops like almonds, apples, avocados, blueberries, cherries, cucumbers, kiwis, melons, and pumpkins, among others.
