If you have a bumblebee in your yard or garden, you may be wondering what can you feed a bumblebee. There are many things you can do to help a bumblebee to survive, but some of the best things you can do are to encourage the bumblebee to find nectar-bearing plants. Fortunately, there are plenty of great ways to do this.

Pollen
Bumble bees forage selectively to meet a variety of nutritional requirements. They also rely on social information from others about the quality of the pollen they find. Bees need a variety of different nutrients, including proteins, carbohydrates and fats.
To understand bumble bees’ foraging behavior, researchers conducted a series of experiments. They used 31 commercial colonies of the bumble bee, B. terrestris, to determine the effects of pollen type and floral cues. Specifically, the team sought to determine whether bumble bees differentiate between normal pollen and artificially produced pollen.
The results showed that bumble bees consumed normal pollen in much larger amounts than artificially produced pollen. However, they did not distinguish between the amino acid content of the two. Moreover, they were only active during times when all species’ flowers were presenting pollen.
In addition, the team investigated whether bumble bees are able to assess the ratio of lipids and proteins in pollen. This is important because lipids are key to various physiological processes in insects, including molting hormone production.
Plant nectar-bearing plants
Plants make nectar, a sweet liquid, from sugars and oils. Nectar is a food source for animals. Animals need good quality food. The most common substances are sugars, amino acids, and vitamins.
Nectar is especially produced by flowers. In addition to its sugar content, nectar contains proteins, vitamins, and other substances. These are used by bees, butterflies, and other insects for their nutrition.
Some plants, such as red clover, provide a good food source for bees and other insects. Red clover enriches the soil with nitrogen.
The amount of sugar in nectar varies depending on the age of the flower. For example, nectar from one day old flowers has a higher concentration of sucrose than that from two days old flowers.
Honeybees prefer sucrose to other sugars. Sucrose is the most phagostimulatory sugar for bees. Bumblebees have been observed robbing nectar from flowers. They can also detect the quantity of nectar without touching the flower.
Sugar
When you see a struggling bumblebee in the wild, you may wonder if you should feed it sugar water. This isn’t the best way to help a stranded critter. You should also consider safety.
The best time to give sugar water to a bee is when it’s not hungry. Be careful to never leave it out for more than a couple of hours. Bumblebees burn through full tummies of nectar very quickly.
There are several different ways to make a’sugar’ water. A simple method is to dissolve sugar crystals in water. Alternatively, you can use dry white table sugar. If you opt for the latter, be sure to stir the mixture until all of the crystals have dissolved.
While there is no hard and fast rule on the exact ratio of sugar to water, a common recipe is to use one part sugar and two parts water. Some beekeepers prefer a more dense syrup.
Liquid diets
A study examined feeding preferences of bumble bee workers. Bumble bees are a member of the hymenoptera family. They feed on pollen and fecal matter. Adult bumble bees have a P:L intake target range between 25:1 and 5:1.
To examine bumble bee nutritional requirements, the researchers provided a pollen blend to four different bee species. The bees consumed the diets for seven days. The relative amount of food consumed varied significantly, as shown in Table 1.
Lipids were the most abundant dietary component, but bees consuming high lipid treatments had a higher risk of death. In contrast, the surviving foragers had a lower nutrient intake compared to those deceased.
A single P:L diet assay showed that bumble bees consumed more protein than fat. This reflects their preferred macronutrient ratios, which have been linked to the fitness of bumblebee colonies.
In addition, bumble bees have a unique nutrient regulation. They prefer pollen with high sterol and amino acid concentrations.
