Wildflower-Bee pacs contain a mixture of annuals and perennials.
Bees are dependent on pollen as a protein source, collecting pollen primarily to feed their larvae. They also use flower nectar and oil as an energy source. Most bees have specialized branched or feathery body hairs that help in the collection of pollen. As they fly from flower to flower, some pollen falls off landing on the pistils (reproductive structures) of other flowers, which can lead to cross-pollination. Bees are the most important pollinating insects.
Some bees produce honey from flower nectar. Honey bees and stingless bees commonly hoard large quantities of honey which is exploited by beekeepers, who harvest the honey for human consumption.
There are about 20,000 or more species of bees worldwide. Bees are found throughout the world except at the highest altitudes, in polar regions, and on some small oceanic islands. The greatest diversity of bee species is found in warm, arid or semiarid areas, especially in the Americas. Many bees are black or gray, but others are bright yellow, red, or metallic green or blue.
