what is the range of a honey bee
Forage (honey bee) As a rule of thumb the foraging area around a beehive extends for two miles (3 km), although bees have been observed foraging twice and three times this distance from the hive. Experiments have shown that beehives within 4 miles of a food source will gain weight, but beyond that the energy expended is greater than that gained during the foraging flight.[1] Foraging at extreme distances wears out the wings of individual bees, reduces the life expectancy of foraging bees and therefore the efficiency of the colony. The minimum temperature for active honeybee foraging is approximately 55 °F (13 °C). Full foraging activity is not achieved until the temperature rises to 66 °F (19 °C). There are small differences in the races of the Western honey bees at what temperature they will start foraging.
Worker bee Workers gather pollen into the pollen baskets on their back legs, to carry back to the hive where it is used as food for the developing brood. Pollen carried on their bodies may be carried to another flower where a small portion can rub off onto the pistil, resulting in cross pollination. Almost all of civilization's food supply (maize is a noteworthy exception) depends greatly on crop pollination by honey bees, whether directly eaten or used as forage crops for animals that produce milk and meat. Nectar is sucked up through the proboscis, mixed with enzymes in the stomach, and carried back to the hive, where it is stored in wax cells and evaporated into honey.
