What is the lifespan of worker bees reared in the spring or summer?

The lifespan of worker bees reared in the spring or summer is typically 5 to 7 weeks. This duration is influenced by various factors, including the season and the amount of work they do. During the seasons of peak activity, spring and summer, worker bees take on roles such as foraging and hive maintenance, which increases their wear and tear and shortens their lifespan compared to those born in the fall or winter.

In contrast, bees reared in the fall or winter have a much longer lifespan of several months. This is because they are not as active during the colder months and are primarily focused on maintaining the hive's temperature and protecting the queen. Therefore, the significant difference in lifespan between summer and winter bees is directly related to their roles and environmental conditions.

Understanding this lifecycle is essential for beekeepers as it informs management practices regarding hive health and productivity throughout different seasons.
