Document Summary
Unit four foraging and reproduction at the individual level, Key information to learn about the foraging behaviour of honey bees includes how foragers find flowers and how flowers attract them. Additionally, you will learn about foraging strategies followed by bees to collect nectar, pollen, water and propolis. However, bees also rob honey from other colonies, a type of. wrong foraging behaviour that may occur during times of nectar dearth. At about three weeks after emergence, workers become field bees that forage for nectar, pollen, water and propolis. Foraging is a risky job because bees are exposed to external dangers and because foraging accelerates their aging process. In the field, bees can be eaten by predators, starve, or get lost. Additionally, field work implies high activity levels, which significantly reduces their length of life. A forager usually lives one to two additional weeks after the onset of foraging activities (28 to 35 days total).
