How Long Do Bees Live? Bee Lifespan Calculator

How long do bees live?

How long do bees live? Anywhere from about two weeks to several years. A summer worker in a hive lives 15–38 days, while the queen of the same colony lives 1–2 years on average (Remolina & Hughes 2008). A nesting mason bee female has about 20 days to do all her work (Bosch & Kemp 2001), and a female carpenter bee can live up to two years (Animal Diversity Web). So the honest answer to "how long does the bee live?" — or "how long to bees live?", as it's often typed — is another question: which bee, and which job does it have?

The calculator above answers that for the five kinds of bee people meet most often in gardens and homes. Pick a type and a role; for hive bees, pick a season too. You'll get the sourced range, a bar chart comparing that role across bee types, and a link to the page with the full details.

Three things decide how long a bee lives:

• Its role. In social bees, egg-laying queens far outlive the workers that do the colony's heavy lifting, and males usually die soon after mating.
• The season it was born in. Bees raised for winter build up body reserves and live for months; bees raised in summer burn out in weeks (Otis 2023).
• How hard it works. Flying is what wears a bee out. Researchers have linked worker deaths to a lifetime flight budget of roughly 800 km (Winston 1987, via deJong 2024).

Bee lifespan by type and role

Here is the life span of a bee for each type and role covered by the calculator, one line each, with a link to the page that explains it in depth. Ranges are averages from studies of real colonies or nests — a few individuals always live longer.

Two figures need a warning. The bumble bee male figure isn't from a research study (see the bumble bee page), and no one appears to have measured the adult lifespan of a sweat bee, so that row describes the life cycle instead. Wasps aren't bees; for yellowjackets and paper wasps, see how long a wasp can live.

Which bee lives the longest?

Among the bees on this page, the longest-lived individuals are queens and carpenter bee females. A queen in a managed hive lives one to two years on average, "can exceed seven years" (UF/IFAS), and up to eight years has been reported (Bozina 1961, cited by Baer et al. 2016). Eastern carpenter bee females live about a year on average and up to two (Animal Diversity Web). At the short end are spring-and-summer males and the workers of busy summer colonies, measured in weeks.

Bee lifespan chart in numbers

Bees live how long, then, in plain numbers? Workers of social bees live weeks in summer, mason bee females a few weeks, carpenter bees a year or so, and queens one to several years. Measured in days, that's a range from about 14 to more than 2,500 — a 180-fold difference between the shortest and longest lives in the same small group of insects.

Which bee is it?

The calculator needs you to pick a type, so here are the quickest field marks from the sources we use:

• Honey bee: less brightly striped than a yellowjacket and hairier (UC IPM), usually seen in numbers at flowers or a hive. Colonies hold 20,000–80,000 workers (FAO).
• Bumble bee: large and very hairy, usually with yellow bands on a fuzzy abdomen (Ohio State; University of Kentucky). Nests hold 30 to upwards of 400 bees (University of Wisconsin).
• Carpenter bee: bumble-bee sized, but the top of the abdomen is "largely bare and appears shiny black" (Ohio State). Often hovering at wooden eaves and decks in spring.
• Mason bee: metallic dark blue, sometimes blue-green; males are about two-thirds the size of a honey bee (Bosch & Kemp 2001). Seen at nest tubes and fruit blossom in spring.
• Sweat bee: small (0.1–0.4 inches), often metallic green, blue or black, and fond of landing on sweaty skin for the salt (WSU; UF/IFAS).

If it's yellow and black with a narrow waist and almost no hair, it may be a wasp — see the wasp lifespan calculator.

Why there is no single "average bee lifespan"

Search for the average life of a bee and you'll often find one number — "about six weeks" is common. That figure describes one group: worker bees in a summer hive. It isn't wrong for them, but it hides almost everything interesting about bees.

About 4,000 species of bee live in North America alone, and most are solitary: each female builds and stocks her own nest, and there are no workers at all. Only a handful of bees live in colonies with queens and workers. When people ask how long is a bee's lifespan, they might be picturing a fuzzy bumble bee on a flower, a honey bee at the hive entrance, or the small green bee drinking sweat from their arm — and those lives differ by months.

Even within one hive, the average life span of a bee depends on what you count:

• Averaging all workers over a year mixes summer bees (15–38 days) with winter bees (150–200 days) and gives a number that fits neither.
• Counting from the egg adds 16–24 days of development before a hive bee is even an adult (Ellis 2015), or a whole year for mason bees, which spend most of their lives as larvae, pupae and resting adults inside cocoons (Bosch & Kemp 2001).
• Counting hibernation doubles a bumble bee queen's adult life: she sleeps for 6–9 months (University of Wisconsin).

That's why this page reports ranges by type and role rather than a single average. If you need one sentence: most bees live a few weeks as active adults, while queens and some solitary females live a year or more.

A bee life from egg to adult

A bee life starts long before you see it on a flower. Every bee goes through egg, larva and pupa before it becomes an adult, and that development can take longer than the adult life. A hive worker takes about 21 days from egg to adult, a queen 16 and a drone about 24 (Ellis 2015). A bumble bee egg hatches after 4–6 days, the larva feeds for 2–3 weeks and the pupa takes about two more (Bumblebee Conservation Trust). Carpenter bees take about seven weeks from egg to adult (Ohio State), while a mason bee's development stretches through the whole summer before it rests as an adult in its cocoon until spring (Bosch & Kemp 2001).

The bee life you see — the weeks of foraging — is the last chapter. For the full stage-by-stage story, see the bee life cycle page in this series.

Do bees live longer in winter?

Yes — at least the bees that live through it. In a hive, workers raised in late summer and autumn become "winter bees" with fat reserves, active food glands and a much longer life: 150–200 days on average (Remolina & Hughes 2008), and often more than seven months in healthy colonies, with a record of 304 days (Otis 2023). For most other bees the opposite is true: workers and males die in autumn, and only mated females survive winter, resting underground or in old nests. The honey bee lifespan calculator shows which bees become winter bees, month by month.

How long do bees live in the wild?

The figures above come mostly from bees living outdoors in colonies or nests, so they are already wild or near-wild lifespans. How long do bees live in the wild versus in a beekeeper's hive? For hive bees the difference is small — a managed colony is still exposed to weather, predators and disease. Laboratory figures are a different matter: bees kept in cages can live longer or shorter lives depending on food, water and temperature, which is why researchers treat cage results with care (Nearman & vanEngelsdorp 2022).

Wild solitary bees face the hardest odds. A nesting mason bee female lives about 20 days on average, and her nest is raided by parasites more often toward the end of the season (Bosch & Kemp 2001). A bumble bee colony can fail before it raises any new queens if there aren't enough flowers (Bumblebee Conservation Trust).

What shortens a bee's life

Bees die young for the same handful of reasons, whatever their species. These are the ones with the best evidence:

• Foraging. Flight is dangerous and wears bees out. A hive worker who starts foraging lives about seven more days on average (Dukas 2008, via deJong 2024), and "once they become foragers, very few worker bees live more than two weeks" (Otis 2023).
• Disease and viruses. Deformed wing virus spread by mites "usually kills" an infected hive bee "within a few weeks" (Otis 2023). Viral infections can also combine with other stresses to shorten lives (Nearman & vanEngelsdorp 2022). The varroa mite life cycle page explains how the mite does it.
• Pesticides. Exposure that weakens a bee's immune system can shorten its life directly or together with viruses, and exposure while still a larva may affect adult lifespan (Nearman & vanEngelsdorp 2022). The Xerces Society lists a pesticide-free environment as one of the three things bumble bees need.
• Poor food. Too few flowers mean weaker bees and smaller colonies; poor nutrition is another stress researchers link to shorter lives (Nearman & vanEngelsdorp 2022).
• Cold, wet weather. It keeps foragers at home and can starve a young bumble bee nest while the queen is still working alone (Bumblebee Conservation Trust).
• Stinging. A honey bee worker that stings a person loses her barbed sting and dies within hours — see how long a bee lives after it stings.

One more trend is worth knowing. For hive bees kept in laboratory cages in the United States, median lifespans in published cage studies fell from an average of 34.3 days in the 1970s to 17.7 days recently, across 111 studies from 1970 to 2019 (Nearman & vanEngelsdorp 2022). The cause isn't known, and the finding is about caged bees, not colonies in the field — the honey bee page looks at that study in detail.

How this bee lifespan calculator works

• One shared data set. Every number comes from the same bee data used by every bee page on this site, so a summer hive worker gets 15–38 days here and on the honey bee and worker bee pages, and a bumble bee worker gets 28–42 days here and on the bumble bee page.
• Roles adapt to the bee. Solitary bees (carpenter and mason bees) have females and males but no workers; social bees have all three.
• Season. Only hive workers and drones change with the season. "Winter" for drones means late-season drones, which a Japanese study found living 75–90 days — though colonies in cold climates evict drones in autumn (Schaumann et al. 2024).
• "Not sure". Shows the span of the measured values across bee types for the role you chose. Estimates (the sweat bee row) are left out of that span.
• Comparison bars use a stretched, logarithmic time scale so that 14 days and 8 years fit on one line.

The figures are averages and ranges from field studies, extension publications and museum species accounts, cited by name throughout. Individual bees vary with weather, food, disease and luck.

Frequently asked questions

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).
