Speed of Work
Honeybees visit up to about 40 flowers per minute depending on floral type, nectar availability and weather conditions. Floral visitation rate by honeybees of some important crops:
Flower | Seconds per visit |
---|---|
Apricot | 10 |
Apple | 68 |
Cherry | 82 |
Raspberry | 116 |
Black currant | 134 |
The longer the time period, the greater the nectar availability. It takes twice as much time to collect a load of nectar compared with a load of pollen. A bee will visit 100–1000 flowers per trip from the hive.
There is general agreement that a single bee will do an average of 10 trips per day (range 7–13). Large single loads of nectar may weigh 70 mg for Italian bees. Sometimes a hive may gain 4–10 kg in a single day. For a 5 kg (11 pounds) gain this means:
In two days a strong hive with more than 20,000 foragers may fill a honey super. This is for nectar, ripe honey has its water fraction reduced significantly.

Famous quotes containing the words speed and/or work:
“The greatest felony in the news business today is to be behind, or to miss a big story. So speed and quantity substitute for thoroughness and quality, for accuracy and context. The pressure to compete, the fear somebody else will make the splash first, creates a frenzied environment in which a blizzard of information is presented and serious questions may not be raised.”
—Carl Bernstein (b. 1944)
“So your work and you shall reinforce yourself.”
—Ralph Waldo Emerson (18031882)
