Glossary
The geographic area that a honey bee colony exploits for nectar and pollen collection. Worker bees can fly up to 5 miles from the hive (a foraging area of approximately 50 square miles), though the majority of productive foraging occurs within 1 to 2 miles of the hive.
Honey bees can theoretically fly up to 5 miles (8 km) from the hive to reach a food source. At this extreme range, however, the energetic cost of the round trip (10 miles) consumes most of the nectar the bee collected, making it marginally profitable or even a net energy loss. The productive foraging range, where foraging is economically beneficial to the colony, is approximately 1 to 2 miles (1.5 to 3 km) from the hive.
Within this 1 to 2 mile radius, the foraging area is approximately 3 to 12 square miles. This means a single colony's foragers are sampling thousands of individual plants across a significant landscape. The diversity of nectar and pollen sources within this area directly determines the colony's honey production, nutritional health, and the flavor profile of the resulting honey.
A foraging flight consumes approximately 0.5 mg of sugar per mile. A bee carries approximately 40 mg of nectar per trip (at approximately 20 to 40% sugar concentration, that is 8 to 16 mg of sugar). A 4-mile round trip (2 miles each way) costs approximately 2 mg of sugar, leaving 6 to 14 mg of net sugar delivery. A 10-mile round trip costs approximately 5 mg, leaving only 3 to 11 mg, and the time spent flying rather than collecting reduces the daily foraging efficiency dramatically.
When we say our honey is "locally harvested in Bradenton, Florida," the foraging range gives that claim specificity: the bees that produced our honey visited flowers within approximately 2 miles of our hive locations. This includes the palmetto scrub, wildflower meadows, citrus groves, and garden flowers within that radius, all contributing to the specific flavor profile unique to our location.
Yes. If the theory that local honey helps with allergies has validity (evidence is limited), the relevant 'local' area would be within the bee's actual foraging range: approximately 1 to 2 miles from the hive. Honey from a beekeeper in the same county but 30 miles away would not contain pollen from your specific neighborhood.
A productive forager makes 10 to 12 foraging trips per day during peak nectar flow. Each trip lasts 30 to 60 minutes (including flight time and flower visits). Over her approximately 3-week foraging career, a single worker bee may make 200 to 300 total foraging flights.
