Workers: about 4–6 weeks (BBCT). Queens: up to about a year, 6–9 months of it hibernating (ADW; University of Wisconsin). Males: about 2 weeks (Pollinator Partnership — not a study). Colony: one season; only mated new queens survive winter.
Bumble bee lifespan
The bumble bee lifespan depends on which member of the colony you're looking at. Workers live about four to six weeks (Bumblebee Conservation Trust). Queens live up to about a year (Animal Diversity Web), and most of that year is spent alone — six to nine months of it hibernating underground (University of Wisconsin). Males live a short life in late summer; a pollinator charity puts it at about two weeks (Pollinator Partnership), though we couldn't find a measured study.
Unlike honey bees, bumble bees (Bombus) don't keep a colony going for years. Each colony lasts a single season: "the colonies are annual, with queens emerging in spring, and producing new queens that same fall which will found new colonies of the following year" (University of Wisconsin). That one fact explains every lifespan on this page.
Enter the bee you saw — queen, worker or male — and the date. The calculator gives the sourced lifespan and shows where that date falls in the bumble bee year, which often tells you what the bee is doing (a big bee on spring flowers is almost always a queen looking for a nest site).
How long do bumble bee queens, workers and males live?
| Bumble bee | Lifespan | When you see them | Source |
|---|---|---|---|
| Queen (foundress) | up to 1 year in all, including 6–9 months of hibernation | early spring (founding) and late summer–autumn (new queens) | Animal Diversity Web; University of Wisconsin |
| Worker (female) | 28–42 days | spring to autumn | Bumblebee Conservation Trust |
| Male (drone) | 14 days (not a measured study) | late summer and autumn | Pollinator Partnership |
Bumble bee queen lifespan
A queen's year runs like this. She emerges as a new queen (gyne) in late summer, builds up fat by feeding in the nest and on flowers — new queens are fed up to three times more pollen as larvae, which makes them big (Bumblebee Conservation Trust) — mates, then digs into loose soil or thatch to hibernate. Over winter she survives on her reserves, protected by alcohol molecules "similar to antifreeze" in her body (University of Wisconsin). She wakes in spring, founds a nest alone, raises workers, and dies in late summer or autumn with her colony. "The original queen, or the founder, of the colony, will die naturally with the remaining workers" (Penn State Extension). Animal Diversity Web gives the maximum as one year.
How long do bumble bee workers live?
About four to six weeks, "so they need to be replaced constantly" (Bumblebee Conservation Trust). Workers are smaller daughters of the queen. The biggest and strongest do most of the foraging; smaller ones often stay in the nest to keep it at the right temperature, defend it and remove dead brood (Bumblebee Conservation Trust). Like honey bee workers, bumble bee workers wear out from flying, but no bumble bee worker survives the autumn — there's no long-lived winter worker.
How long do male bumble bees live?
Males appear late in the season. "Once grown, males leave the nest to mate with new queens from other colonies, and never return. They spend their days hanging out on flowers, drinking nectar, and flying around looking for queens" (Bumblebee Conservation Trust). They die before winter. The Pollinator Partnership puts their life at about 14 days; that's a charity's figure from an advocate's account, not a study, so the calculator flags it.
Bumble bee development time
Every bumble bee — queen, worker or male — develops through egg, larva and pupa. The eggs hatch "after four to six days"; the larvae feed for two to three weeks and then spin silky cocoons; "after two weeks, the new bumblebees force their way out" (Bumblebee Conservation Trust). New adults are "weak, soft, and floppy" at first, with silvery-white hair that darkens to its normal colours; it takes a day for their bodies to harden and their wings to dry. Estimates of the time to the first workers vary: two to three weeks after the eggs are laid (University of Wisconsin) or about three to four weeks (Penn State Extension).
Inside a bumble bee nest
A queen starts her nest alone. She makes wax flakes from her body, shapes a cup and fills it with nectar, packs pollen into a clump and lays her first eggs on it, then sits on the brood shivering her flight muscles to keep it warm, sipping from the nectar pot when the weather is too bad to forage (Bumblebee Conservation Trust). The nest has to stay at a constant 25–32 °C (Bumblebee Conservation Trust) — about 30 °C "even when the outside temperature is far colder, even down to 0C" (University of Wisconsin). Later in the summer, once the queen stops laying workers, some workers start laying unfertilized eggs of their own, which become males — the "competition phase" (Penn State Extension).
Why some colonies end early
The riskiest weeks are the start. A lone queen must keep her brood warm and leave to collect food at the same time, and "unfortunately, some nests and queens die at this point" (Bumblebee Conservation Trust). Later, a colony that can't gather enough food may fail "before they can produce queens, as there are not enough flowers to feed on" — so it never passes its genes on (Bumblebee Conservation Trust).
Telling bumble bee queens, workers and males apart
Size and season are the best clues. Queens are the biggest: as larvae "new queens are fed up to three times more pollen", which makes them very large (Bumblebee Conservation Trust), and you'll see them in early spring searching low over the ground for nest sites, or in late summer and autumn feeding up before hibernation. Workers are smaller daughters seen from spring to autumn; the smaller and weaker ones tend to stay in the nest while bigger ones forage (Bumblebee Conservation Trust). Males appear late in the season and spend "their days hanging out on flowers, drinking nectar, and flying around looking for queens" (Bumblebee Conservation Trust) — a bumble bee dozing on a flower head in late summer is often a male. The calculator asks which one you saw because their lives differ by months.
Do bumble bees survive winter?
Only the new queens. "As summer fades to autumn, the old queen and all the workers and males die off, while the new queens enter hibernation" (Bumblebee Conservation Trust). The mated queens dig into loose soil, banks of earth and thatch — and sometimes flowerpots — and stay there for six to nine months (University of Wisconsin; Bumblebee Conservation Trust).
So when people ask how long bumble bees live for, the winter is the key: the queen you see in March or April was born the previous summer and has already lived through the cold months. She "spends much of [her] time resting on the ground with very little flying or feeding" at first, research at Queen Mary University of London found — so a sluggish queen in spring is often fine (Bumblebee Conservation Trust).
Winter-active bumble bees
There's a modern exception. Since the 1990s, naturalists in Britain have recorded bumble bees active in winter, almost all buff-tailed bumblebees (Bombus terrestris). Some of the queens produced over summer now set up nests in autumn instead of hibernating, feeding on winter flowers such as Mahonia and winter honeysuckle; winter nests have been recorded as far north as Dundee (Bumblebee Conservation Trust). Many queens seen in February have simply woken early.
The bumble bee year at a glance
| Month | Northern Hemisphere | Southern Hemisphere |
|---|---|---|
| January | Queens hibernating | Males and new queens |
| February | Queens hibernating | Males and new queens |
| March | Queens waking | Males and new queens |
| April | Queens waking | Colony ending |
| May | Queens founding nests | Queens hibernating |
| June | Colony growing | Queens hibernating |
| July | Males and new queens | Queens hibernating |
| August | Males and new queens | Queens hibernating |
| September | Males and new queens | Queens waking |
| October | Colony ending | Queens waking |
| November | Queens hibernating | Queens founding nests |
| December | Queens hibernating | Colony growing |
Months are approximate: Wisconsin queens typically emerge in mid to late April and early May, while the Bumblebee Conservation Trust gives roughly March to May for the UK, and colonies switch to raising males and new queens anywhere from late June to August–September depending on species (University of Wisconsin). The Southern Hemisphere column is our six-month shift. For the colony stage by stage, see the bumble bee life cycle page in this series.
Bumble bee vs honey bee lifespan
Both are social bees with a queen and workers, but their lifespans differ because their colonies do:
| Bumble bee | Honey bee | |
|---|---|---|
| Queen | up to 1 year | 1–2 years; can exceed 7 years |
| Worker | 28–42 days | 15–38 days summer; 150–200 days winter |
| Male | about 2 weeks (charity figure) | 21–90 days reported |
| Colony | one season (annual) | years (perennial) |
| Winter | only mated queens survive, hibernating alone | the whole colony survives as a cluster of winter bees |
| Colony size at peak | 30 to upwards of 400 (Wisconsin) | tens of thousands |
Sources: Bumblebee Conservation Trust; Animal Diversity Web; University of Wisconsin; Penn State Extension; Remolina & Hughes 2008; UF/IFAS; Schaumann et al. 2024. Penn State sums it up: "Bumble bees are an annual species that have one queen per year, whereas honey bees are perennial species, with one queen that can live for several years." For month-by-month honey bee figures, see the honey bee lifespan calculator.
One practical difference: bumble bees are excellent at "buzz pollination", vibrating their flight muscles to shake pollen out of flowers such as blueberries and tomatoes, which honey bees find harder to reach (Penn State Extension).
How to help bumble bees live longer
The Xerces Society's Bumble Bee Watch puts it in three lines: bumble bees need "1. Flowers on which to forage 2. A place to build their nest 3. A pesticide free environment."
- Flowers from spring to autumn. A queen must feed on spring flowers before she can nest, and a colony fails before it raises new queens "as there are not enough flowers to feed on" (Bumblebee Conservation Trust). Early blossoms feed waking queens; late flowers feed new queens fattening up for hibernation.
- Nest sites. Queens nest in long tangled grass, compost heaps, bird boxes and abandoned mouse and vole holes (Bumblebee Conservation Trust) — "cavity nesting", as the University of Wisconsin calls it. Leave some rough, undisturbed corners.
- Places to rest and hibernate. Long grass and undisturbed leaf litter give resting bees safety; loose soil and banks are hibernation sites (Bumblebee Conservation Trust).
- Avoid pesticides. A pesticide-free garden is one of the three essentials (Xerces Society).
- If you dig up a hibernating queen, cover her again loosely with the same material so she can dig out later; if she won't settle, leave her somewhere sheltered such as under leaf litter. Don't take her indoors (Bumblebee Conservation Trust).
- A tired bee? Usually it's resting — queens rest for about 30 and up to 45 minutes. Only if a bee has been on the ground much longer and there are no flowers nearby, offer a drop or two of 50/50 white sugar and water on a spoon; never honey or brown sugar (Bumblebee Conservation Trust).
- A bee stuck indoors? Open a window, or ease it into a cup with a piece of card and release it outside near flowers (Bumblebee Conservation Trust).
How this calculator works
- Lifespans: workers 28–42 days (Bumblebee Conservation Trust); queens up to 1 year (Animal Diversity Web; University of Wisconsin); males 14 days (Pollinator Partnership, flagged as not a study). These are the same shared figures as on the bee lifespan calculator.
- Season stage: the month of the date you enter is matched to the bumble bee year in the table above. Southern Hemisphere months are shifted by six — our assumption.
- Queens: the result depends on the season — a spring queen is a foundress who will die with her colony; a late-summer or autumn queen is a new queen with hibernation and a full year ahead.
- Workers and males: the date shown is an upper limit counted from the day you saw the bee, because you don't know when it emerged.
Species, weather and flowers all shift the calendar by weeks, so treat the months as a guide for common temperate species.
How long to bumble bees live — a quick recap
If you came here asking "how long to bumble bees live?", here's the one-line answer: workers about a month to six weeks, males a couple of weeks, and queens up to a year — half of it asleep underground.
Frequently asked questions
How long do bumble bees live?
Workers about four to six weeks (Bumblebee Conservation Trust); queens up to about a year, including 6–9 months of hibernation (Animal Diversity Web; University of Wisconsin); males about two weeks (Pollinator Partnership).
What is the bumble bee lifespan for a queen?
Up to about a year: she emerges in late summer, hibernates 6–9 months, founds a colony in spring and dies with it in autumn.
How long do bumble bee workers live?
About four to six weeks, so the queen keeps replacing them all summer (Bumblebee Conservation Trust).
How long do male bumble bees live?
A short time in late summer and autumn — about two weeks according to the Pollinator Partnership, which isn't a measured study.
Do bumble bees survive winter?
Only mated new queens, hibernating alone in loose soil or thatch. The old queen, workers and males die in autumn (Bumblebee Conservation Trust).
How long do bumble bees hibernate?
Six to nine months (University of Wisconsin).
Why do I see bumble bees in winter?
Some buff-tailed bumblebees in the UK now nest in autumn and stay active on winter flowers; queens seen in February have often woken early (Bumblebee Conservation Trust).
Do bumble bees live longer than honey bees?
Bumble bee workers live a little longer than summer honey bee workers (15–38 days), but honey bee queens and winter workers live much longer than any bumble bee.
How many bees live in a bumble bee colony?
From about 30 to upwards of 400 bees at its peak, depending on species (University of Wisconsin). The bumble bee life cycle page follows a colony month by month.
Should I give a tired bumble bee sugar water?
Only as a last resort, if no flowers are near and it has been on the ground a long time: one or two drops of 50/50 white sugar and water, never honey (Bumblebee Conservation Trust).
How long do bumble bees live for in a garden?
The same as anywhere: workers weeks, queens up to a year. Flowers from spring to autumn, nest sites and no pesticides help colonies reach their full lifespan (Xerces Society).
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).
