How Long Do Bees Live? Lifespan of Workers, Drones and Queens

Honey bee lifespan at a glance

Lifespan in the western honey bee depends far more on a bee’s role and the season than on its genes. Queens and workers hatch from the same kind of fertilized egg, yet a queen can outlive a summer worker roughly 15 to 40 times over.

Development time before adulthood adds a little: about 21 days from egg to adult for a worker, 24 for a drone and only 16 for a queen.

Why summer worker bees die so young

A summer worker spends roughly her first three weeks inside the hive, cleaning cells, feeding larvae, building comb and guarding. Then she becomes a forager and makes many flights a day to collect nectar, pollen and water. Foraging is dangerous and exhausting. Birds, spiders and hornets catch bees, bad weather strands them, and their wings fray with use.

Flight is also hard on the body. Research has found more cellular damage in the flight muscles of bees with long flight experience, and a forager’s energy reserves and immune defenses fall quickly. Experiments in which foragers were made to go back to nursing showed that some signs of aging slowed or even reversed, which suggests that in bees it is the job, not just the calendar, that sets the pace of aging.

Because summer workers die so fast, a colony loses roughly 1 percent of its workers every day and must replace them constantly. The queen’s high egg-laying rate in summer keeps the population steady.

How winter bees live for months

In cold climates, the bees raised in late summer and autumn are different. These winter bees do little brood rearing or foraging, and they build up large fat bodies, tissue that stores protein and a substance called vitellogenin, which seems to protect them from aging. They spend the winter in a tight cluster, shivering their flight muscles to keep the center warm and slowly eating the stored honey. In spring they rear the first new brood before dying, typically after 4–6 months; the longest have been reported to live about 8 months.

How long do queen bees live?

A honey bee queen typically lives 2–5 years. She mates in the first weeks of her life, stores millions of sperm, and then lays eggs for the rest of it, protected inside the hive and fed constantly by workers. As her stored sperm runs low, she lays more unfertilized eggs, which become drones, and the workers usually raise a replacement queen. Many beekeepers replace queens every year or two, so few managed queens reach old age. See what a queen bee does for her full life story.

How long do drones live?

Drones, the male bees, exist only to mate with young queens from other colonies. A drone that mates dies at once, because his genital organs tear away during mating. Unmated drones live a few weeks to about two months. When nectar runs short in autumn, the workers stop feeding them and drag them out of the hive, where they soon die. In colder climates, a colony enters winter with no drones at all.

How long do bumblebees and solitary bees live?

Bumblebees, such as the buff-tailed bumblebee, have annual colonies. A queen emerges from hibernation in early spring, starts a nest alone and raises workers that live a few weeks each, often around two to six. In late summer the colony produces new queens and males, then dies out. Only the young mated queens survive, hibernating alone in the soil, so a bumblebee queen lives about a year in total.

Most bees are solitary: each female builds her own nest and lays eggs on a store of pollen and nectar. Adults such as mining bees and mason bees usually fly for only a few weeks to a couple of months. Their offspring spend most of the year as larvae and pupae sealed in their cells, so the whole life cycle often takes a year.

Bee lifespans compared with other social insects

Social insects show some of the most extreme lifespan differences in the animal world between queens and workers of the same species. Honey bee queens live years while workers live weeks. In ants the gap is even bigger: some ant queens live for decades, as explained in how long ants live. Biologists study these insects to learn how the same set of genes can produce such different lifespans.
