Bees typically feed on nectar and pollen, though there are exceptions – for instance, in South America vulture bees have been known to consume decayed meat as their sustenance source.
Bees are drawn to gardens and fields that provide a diversity of flowering plants, especially gardens with fruiting trees. Bees rely on nectar – an energy-giving fluid composed of glucose and fructose sugars – as a food source.

Nectar
Nectar is a sweet, viscous liquid produced by glands called nectaries on flowering plants’ petals, stems and leaves. Its sugar content can range between 3-80% while it also contains proteins, salts, acids and essential oils. Bees use nectar for energy purposes; their stomachs help them process it further by using enzymes to decrease water content while adding essential nutrients into their nectar mix. Once enough nectar has been consumed by bees they return to their hive and regurgitate the nectar mixture into an internal storage container called crops – an internal storage system designed specifically for this task.
Bees use “pilfering” to collect pollen as they forage for nectar sources; pollen serves as the male component of flowers’ reproductive organs and when transferred by bees it helps pollinate plants and enable fruit bearing blooms.
Honey
Honey is a nutritious source of energy for bees. Composed largely of glucose and fructose sugars, nectar must be extracted by visiting flowers with their long tongue-like appendage called a proboscis to reach into hidden nectararies within them and extract nectar; once back at their hive they store this juice within their comb.
Hylaeus kuakea) bees can often be found gathering nectar from various plants and can often be seen buzzing around picnics or backyards in search of sweet treats like watermelons, soft drinks or frozen desserts. Other bee species, including Halictidae bees (green sweat bee) and mining bees (Andrena agilissima) collect pollen from various flowers within their foraging territory; queen bees on the other hand typically consume honey as their diet and source of protein that helps them produce fertile offspring as well as providing energy-rich protein sources essential to build colonies over time while fuelling labor-intensive activities like building and polinizing activities.
Water
Researchers have conducted field and laboratory experiments on bees’ water preferences. Their experiments reveal that bees prefer clean, freshwater over dirty or chlorinated waters; also showing their preference for waters containing specific mineral concentrations.
Bees feed on nectar and pollen as the cornerstones of their diets. Nectar provides their basic energy needs while pollen supplies protein, vitamins, and minerals – thus fulfilling their primary role as pollinating insects. Male bees may take advantage of flowers they visit by pilfering pollen from flowers while females collect it specifically to feed their larvae within their hive.
Any interference to their diets – from high temperatures linked to climate change or fungicides to poisoned water sources – could cause starvation and/or death for bees, necessitating people to be aware of what kind of water they offer as bee food; water that contains pesticides or harmful chemicals could poison or kill bees searching for sustenance.
Royal Jelly
Royal jelly is produced by worker bee hypopharyngeal glands and mandibular glands between the sixth and twelfth days of their lives, while queen bees consume it exclusively throughout their long lives, which last 50 times longer than average bee lives. This unique diet may explain why queen bees differ both physiologically and behaviorally from worker bees.
Royal jelly, when harvested in its natural state, is a sticky white substance with an unpleasant mixture of faintly sweet, mildly meaty flavour similar to condensed milk. It features low pH levels and contains proteins, sugars, lipids, vitamins minerals and amino acids in abundance.
Beekeepers need to wait for just the right moment to harvest royal jelly from queen cells – typically three to four days post grafting of worker larva into a queen cell – then collect it by hand using either a syringe or vacuum device, before straining out wax and old larval skins before processing into honey, lotion or capsule form for consumption.
