Summer workers: 15–38 days; winter workers: 150–200 days (Remolina & Hughes 2008). Jobs: cleaning 0–4 days, nursing 4–12, building 12–17, receiving and guarding 17–21, foraging from day 21 (deJong 2024). As a forager: about 7 more days (Dukas 2008).
How long do worker bees live?
How long do worker bees live? In a honey bee colony, a worker that emerges in spring or summer lives 15–38 days on average, while one that emerges in autumn lives 150–200 days (Remolina & Hughes 2008). That is the whole adult life of the bees that do everything in the hive except lay eggs and mate: they clean, feed larvae, build comb, process nectar, guard the entrance and fly out for food, water and resin.
The worker bee lifespan is short because the work is hard. A summer worker spends her first two to three weeks inside the hive and the rest outside, and "once they become foragers, very few worker bees live more than two weeks" (Otis 2023). The timeline calculator above turns her emergence date into a dated plan of her likely jobs and the window in which her life is most likely to end.
Workers are all female. They are daughters of the queen, but they don't normally lay eggs while she is healthy, and they develop from egg to adult in about 21 days (Ellis 2015).
Worker bee lifespan in summer and winter
The same colony raises two very different kinds of worker:
- Summer workers — 15–38 days on average (Remolina & Hughes 2008). deJong (2024), citing Winston, puts the average summer lifespan at 38 days, and Otis (2023) notes it is "rare for a 'summer bee' in a colony with a functioning queen to live for 50 days."
- Winter workers — 150–200 days on average (Remolina & Hughes 2008), often more than seven months, and up to 304 days (Otis 2023). They don't follow the age-based job schedule; they keep the winter cluster warm, feed one another and the queen, and raise the first brood in early spring (deJong 2024).
What switches a worker from one type to the other is the state of the colony in autumn: less pollen, less brood and less brood pheromone. For the month-by-month pattern, see the honey bee lifespan calculator, which gives the same numbers as this page.
How long does a worker honey bee live once she forages?
How long does a worker honey bee live after she starts foraging? About a week more on average: "the average life expectancy of a bee entering the forager stage is an additional seven days" (Dukas 2008, via deJong 2024). Not every worker gets there — only about 60% survive to the forager stage (Prado et al. 2020, via deJong 2024).
Life cycle of a worker bee: from egg to forager
The life cycle of a worker bee has two halves: about three weeks of development sealed in a wax cell, then a few weeks of adult work that moves outward through the hive with age.
| Stage | Days from egg | What happens |
|---|---|---|
| Egg | 0–3 | the queen lays one fertilized egg in a worker cell; it hatches in about three days (Ellis 2015) |
| Larva | 3–9 | fed royal jelly for three days, then a honey-and-pollen mix; the cell is capped six days after hatching (FAO) |
| Pupa (capped cell) | 9–21 | the larva spins a cocoon and changes into an adult under the wax cap |
| Adult emerges | 21 | she chews through the cap (Ellis 2015; FAO) |
Inside the cell, temperature matters: brood needs 33–36 °C to survive, and the adult bees keep it there by clustering, shivering and fanning (Seeley 1985, via deJong 2024). Once she emerges, her adult life begins — and that is what the timeline above counts. For the stages themselves, see the bee life cycle; to date brood on a frame, use the honey bee brood calculator.
Worker bee jobs by age
Workers change jobs as they age, a pattern called age polyethism. These are the typical age bands for summer workers, from the American Bee Journal's review of the research (deJong 2024):
| Age | Typical jobs |
|---|---|
| Days 0–4 | Cleaning cells |
| Days 4–12 | Nurse bee: feeding larvae |
| Days 12–17 | Comb building and capping honey (wax glands at their peak) |
| Days 17–21 | Receiving nectar, fanning, removing dead brood; the oldest guard the entrance |
| Day 21+ | Forager: nectar, pollen, water and propolis |
- Cleaning (days 0–4). Her first job is cleaning herself and the cells around her, ready for new eggs and food.
- Nursing (days 4–12). A nurse bee makes brood food in glands in her head and feeds the larvae. Nurse bees also tend the queen.
- Building (days 12–17). Her four wax glands are at their peak — most productive at 12–18 days (FAO) — so she builds comb and caps ripe honey. Wax is expensive: it takes about 8.4 kg of honey to make 1 kg of wax (Winston 1987, via deJong 2024).
- Middle age (days 17–21). She receives nectar from foragers and turns it into honey, fans air through the hive, removes dead larvae and carries out corpses. The oldest of these middle-aged bees guard the entrance — about 75 guards at a time in one study (Moore et al. 1987, via deJong 2024).
- Foraging (day 21 onward). She collects nectar, pollen, water and plant resin. Some foragers are scouts that search for new food and report it with the waggle dance.
The schedule bends to the colony's needs. Young bees can start foraging early if the colony loses its foragers, and older bees can go back to nursing if there are no young ones — though neither does the job as well (deJong 2024).
When workers change jobs early
The age schedule is a tendency, not a rule. The switch to foraging is driven by juvenile hormone, which rises as a worker ages; her vitellogenin and brood-food glands decline at the same time (Otis 2023). If a colony loses its foragers, young bees speed up and start foraging early; if it lacks young bees, older bees can go back to nursing. Neither change is seamless: precocious foragers "are heavier and less efficient flyers than regular-aged foragers, and they are more likely to fail to return," and foragers that revert to nursing have smaller brood-food glands (deJong 2024, citing Rueppell 2007, Perry et al. 2015 and Robinson et al. 1992).
Signs of an old worker
You can often spot a worker near the end of her life. "Older foragers can be recognised by their tattered wings and thinning hair" (Seeley 1995, via deJong 2024). Worn wings mean slower, less efficient flights, and since a worker's life is limited by flight more than by days, a bee with ragged wings is close to the end whatever her calendar age. A colony has 20,000 to 80,000 of these workers at any time (FAO), so hundreds die and are replaced every day in summer.
Forager bee lifespan
The forager bee lifespan is the last and shortest part of a worker's life. Foragers fly at about 25 km/h, wear their wings ragged and lose hair; those that escape predators and accidents eventually die of exhaustion "after flying about 800 km" (Winston 1987, via deJong 2024). That 800 km budget is why foraging age, not calendar age, decides when most workers die.
How far do worker bees fly?
In a lifetime, roughly 800 km — the flight budget researchers link to a worker's natural death (Winston 1987, via deJong 2024). At a cruising speed of about 25 km/h, that's around 32 hours in the air spread over her foraging days. How far she goes on each trip depends on where the flowers are: scouts search beyond the known food sources and report new finds to the other foragers with the waggle dance, which encodes both direction and distance (deJong 2024).
How much honey does a worker bee make in her life?
You will often see "one-twelfth of a teaspoon". We couldn't trace that figure to a study, so we don't use it. What the research does show is how much honey goes into the colony's own needs: about 8.4 kg of honey to make each kilogram of wax (Winston 1987), and enough stored honey to fuel a winter cluster for months.
Why foraging shortens a worker's life
Three things happen when a worker becomes a forager:
- Her body changes. She loses about 40% of her body mass as her abdomen and gut slim down for flight, and her flight muscles store more glycogen (Harrison 1986, via deJong 2024). Her brood-food glands shrink and her vitellogenin — a storage protein linked to long life — falls to low levels (Otis 2023).
- Flight wears her out. After about 800 km of flying, her ability to turn carbohydrate into stored energy fails and she can't recover from exertion (Winston 1987, via deJong 2024).
- The outside world is dangerous. Birds, spiders, wasps, weather and pesticides all take foragers. That's why the average forager lives about seven days after starting (Dukas 2008).
Winter bees prove the point from the other direction. They rarely fly, keep their storage proteins high and live for months (Otis 2023). Diseases that make bees forage early, such as Nosema ceranae, shorten lives by bringing foraging forward (deJong 2024).
How this timeline works
- Jobs: the age bands in the table (deJong 2024) are added to the emergence date you enter. The current job is highlighted if she is still alive.
- End of life: summer workers get 15–38 days and winter workers 150–200 days (Remolina & Hughes 2008), the same shared numbers as the honey bee and bee lifespan calculators.
- Season: you choose summer or winter. If you're unsure, bees emerging from March to August are summer bees; from late August and through autumn more and more become winter bees (Otis 2023).
- Status: "alive", "in the end-of-life window" or "probably no longer alive" compares today's date with the range — averages, so an individual can live longer.
This is a typical schedule. A real colony shifts its workers between jobs depending on what it needs, so treat the dates as a guide, not a timetable.
Frequently asked questions
How long do worker bees live?
15–38 days in summer and 150–200 days in winter, on average (Remolina & Hughes 2008).
What is the worker bee lifespan in summer?
15–38 days on average; the average summer lifespan is often given as 38 days (Winston 1987), and few reach 50 (Otis 2023).
How long does a worker honey bee live after she starts foraging?
About seven more days on average (Dukas 2008, via deJong 2024).
What jobs do worker bees do by age?
Cleaning (days 0–4), nursing (4–12), comb building (12–17), nectar receiving, fanning and guarding (17–21), then foraging from about day 21 (deJong 2024).
What is a nurse bee?
A young worker, about 4–12 days old, that feeds the larvae with brood food from glands in her head (deJong 2024).
What is the life cycle of a worker bee?
Egg (3 days), larva (capped 6 days after hatching), pupa, and adult at 21 days (Ellis 2015; FAO); then about two to three weeks of hive work and a short foraging life.
How far do worker bees fly?
Roughly 800 km in a lifetime before they die of exhaustion (Winston 1987, via deJong 2024).
How much honey does a worker bee make in her life?
The common '1/12 teaspoon' figure isn't traceable to a study, so we don't quote it. Making 1 kg of wax uses about 8.4 kg of honey (Winston 1987).
Are all worker bees female?
Yes. Workers are the queen's daughters; males are drones (Ellis 2015).
Do winter worker bees do the same jobs?
No. Winter bees are generalists — keeping warm, feeding and tending the queen — without the age schedule (deJong 2024).
Why do worker bees die so young?
Foraging: the risks outside, and the wear of about 800 km of flying (Winston 1987; Dukas 2008).
These calculators give estimates from research and extension figures, for education. Bees are important pollinators — never spray a swarm or a colony. For a swarm or bees in a wall, contact a local beekeeper, a bee-removal specialist or your Extension office (Mississippi State; UGA Extension). If a sting causes trouble breathing, swelling of the face or throat or faintness, call emergency services (UC IPM).
