Wild bees are known for their omnivorous diet, and there are various sources of pollen and nectar available. These provide the energy needed to perform their daily tasks, while nectar also provides the necessary balance of water and nutrients in the diet. Other sources of food include overripe fruit, the sweet secretions of extra-floral nectaries, and meat.

Pollen
Pollen is what wild bees ingest and is the foundation of bee-flower interactions. Pollen nutrition is important for many reasons, from the maintenance of wild plant communities to fruit-crop productivity. In this article, we’ll discuss the basics of pollen nutrition and how we can protect bees and their habitats.
Bees pollinate most crop plants and wild plants worldwide. Without pollination, most plants wouldn’t be able to reproduce and produce seeds. Bees pollinate 80 percent of all flowering plants and 75 percent of all fruits in the United States. Bees eat a lot of pollen, and pollen is their primary source of protein, lipids, and carbohydrates.
Pollen is not always available to honey bees. During the winter, fewer plants bloom. The bees will collect pollen from flowers and bring it back to the colony. There, they will add glandular secretions to the pollen, which prevent harmful bacterial activity. These secretions also make the pollen better-tasting. The pollen is then consumed quickly by the colony.
Nectar
Whether wild bees are responding to climate change or urbanization isn’t entirely clear. In a study of 40 wild bee species from a national park in California, researchers found that they used creative and innovative tactics to obtain sugar during periods of scarce flower nectar. They also found that wild bees may be using honeydew as an alternative fuel source.
Bees’ diets include nectar and pollen. Both provide energy and help maintain water balance. In addition to nectar, honey bees have been observed to eat over-ripe fruit, sweet secretions from extra-floral flowers, and even meat.
Honey
Honey is the main source of nourishment for honey bees. While some species rely solely on plant pollen and nectar, others are scavengers and hunter-gatherers. The honey bee, with its numerous hairs on its body, collects pollen on its setae, which are sticky parts on the bee’s body. The bee then moves the pollen to a special storage area on its hind legs called a pollen basket. If the bee does not have this basket, it may store the pollen in special crops that they can find on their own.
During colder months, the bees do not completely forage for food. They cluster together to keep warm, and during the winter months, they store honey to last until the spring. It’s also a good source of energy, with lots of sugars and nutrients.
Stored food
When feeding your wild bees, they need some kind of protein source. It is important to keep them well-fed to maintain their health. Honey is a good option because it helps strengthen their immune system and keeps them healthy. Alternatively, you can feed them sugar water instead. It is important to check the size and moisture content of the syrup before giving it to your colony.
A common problem for bees is lack of nutritional diversity. Thankfully, there are many initiatives underway to increase natural forage for these bees. By sowing wildflowers, you can improve the health of your bees and provide them with a wide variety of healthy forage. You can also cut back on mowing to make more space for flowering plants. Furthermore, studies are underway to discover the types of pollen that bees need to survive, and tailor seed mixes accordingly.
