Many native bees species or other pollinator species depend on one or a few species of flowers for their diet. The monarch butterfly is famous for its dependence on milkweed. Without milkweed, it would cease to exist. In contrast, the honey bee can utilize an extremely large range of pollen and nectar sources. However, when a forager is collecting nectar or pollen, she will stick to one type of flower to collect her load, even returning to the same branch of the same plant to pick up where she left off when she collected her last load. This flower fidelity is encouraged by the way a hive communicates the most desirable pollen or nectar sources to its foragers, recruiting many foragers to a single source through the waggle dance.
