Bee vs wasp: how to tell them apart, and why both matter

Late August, a picnic table, a can of lemonade. A striped insect lands on the rim. Is it a bee, busy with flowers and best left alone, or a wasp, which might crawl into your drink? Ten seconds of careful looking will tell you.

The quickest way to tell a bee from a wasp: bees are hairy and stocky, and they feed their young on pollen and nectar. Most wasps are smooth and slender, with a narrow “waist,” and they feed their young on other insects. Wasps such as yellowjackets can sting again and again. Only worker honey bees usually leave their barbed sting in your skin.

How can you tell a bee from a wasp?

Check the hair, the body shape and what the insect is doing. Bees are covered in “long, closely-spaced, branched hairs” that carry pollen, while most wasps are “very sparsely hairy,” with short, unbranched hairs, says Montana State University Extension. Wasps usually look smooth and shiny, with a narrow waist.

Here is our side-by-side guide, built from university extension and government sources.

Bee vs wasp: how to tell them apart

Feature	Bees (honey bees, bumble bees)	Social wasps (yellowjackets, hornets, paper wasps)
Body hair	Dense, branched hairs that hold pollen	Sparse, short and unbranched; looks smooth
Shape	Stocky, rounded	Slender, with a narrow “waist”
Food for the young	Pollen and nectar	Insects and other protein
Food for adults	Nectar and pollen	Mostly sugar: nectar, fruit, and sweet drinks in late summer
Sting	Honey bee workers: barbed, usually stays in skin and the bee dies. Bumble bees: can sting repeatedly	Smooth; can sting repeatedly
Nest	Honey bees: comb in hives or cavities. Bumble bees: small nests, often in the ground. Most other bees: solitary tunnels	Paper made from chewed wood fibre, under eaves, in the ground or hanging from trees
Colony size	Honey bees 20,000–90,000; bumble bees 50–400	Yellowjackets 1,500–15,000; paper wasps 15–200
When you’ll meet them	On flowers; unlikely to sting unless trapped or stepped on	Yellowjackets at food and bins, especially in late summer and autumn

The table describes the bees and wasps you are most likely to meet; there are thousands of species and some break the rules.

What about legs? Some guides say wasps fly with legs dangling. In fact it varies between wasps. Western Australia’s agriculture department says yellow paper wasps let their back legs dangle in flight, while invasive European wasps hold theirs close to the body. So use hair and shape first.

What do bees and wasps eat?

Bees are vegetarians. “Bees, on the other hand, are total vegetarians and only eat plant nectar and pollen,” says the University of Georgia, while yellowjackets and hornets are meat-eaters. More precisely, wasps feed their larvae on insects and other protein, while the adult wasps themselves live mostly on sugar.

That one difference explains much of the rest: branched hairs for carrying pollen in bees, and hunting behaviour in wasps. Those are a structural and a behavioural adaptation, two of the three kinds explained in animal adaptations explained.

Ohio State University Extension explains the split. Adult yellowjackets mainly eat sugary food, while their larvae need protein such as insects, meat and fish, says the fact sheet. In return, the larvae “secrete a sugary substance fed upon by the adults.” Paper wasps “feed on nectar and insects,” says Texas A&M AgriLife Extension.

Many wasps hunt the same garden pests that ladybugs eat, and wasps themselves end up as food for bigger hunters: dragonflies eat “almost any insect smaller than themselves, including gnats, mosquitoes, wasps and other dragonflies,” says Ohio State University Extension. See what dragonflies eat.

Why does a honey bee die after stinging, but a wasp doesn’t?

Because of barbs. A worker honey bee’s (Apis mellifera) sting has backward-pointing barbs near the tip. In skin it can lodge and be “torn loose from the abdomen,” a 2015 study in Biology Open found, and the bee dies from the injury. Wasp stings have no large barbs, so a wasp can pull its sting out and use it again.

Zi-Long Zhao and colleagues pushed honey bee and paper wasp stings into pig skin in the lab. Pulling the honey bee sting back out took about 3.3 times the force needed to push it in. The paper wasp sting slid out easily. “Wasp stingers have no barbs and can be used repeatedly,” says the UC Statewide IPM Program.

Not every bee is a one-shot stinger. “Unlike honey bees, bumble bees can sting repeatedly like wasps,” says Cornell University. And males can’t sting at all: male honey bees (drones) have no sting, and male cicada killer wasps “are aggressive but cannot sting,” notes Texas A&M AgriLife Extension.

Which is more aggressive, a bee or a wasp?

Usually the yellowjacket, especially late in summer, but “wasp” covers very different insects. Honey bees “are unlikely to sting unless trapped or stepped on,” says UC IPM, and paper wasps “are rarely aggressive.” Ground-nesting yellowjackets “tend to defend their nests vigorously,” and their defensive behaviour increases as colonies grow and food gets scarce.

There is a reason for the late-summer trouble. By late summer, yellowjacket colonies stop growing and need large amounts of sugar to feed the queen and workers, so foragers turn up at picnics, bins and ripe fruit, explains UC IPM. Bumble bees, by contrast, are “docile when alone,” says Cornell.

Wasp stings may also hurt more. Wasp venom has “more protein enzymes because they’re hunting rather than gathering,” says Keith Delaplane, director of the University of Georgia’s Bee Program, and “the sting of a hornet is a lot more painful than the sting from a bee.”

Are hornets and yellowjackets wasps?

Yes. Hornets and yellowjackets are both social wasps in the family Vespidae. “True” hornets belong to the genus Vespa, and the only one established in North America is the introduced European hornet, says Penn State Extension. The bald-faced hornet (Dolichovespula maculata), despite its name, “is not a ‘true’ hornet – it is a yellowjacket.”

Names get muddled in everyday speech too. “Yellowjackets are often called ‘hornets,'” notes Texas A&M AgriLife Extension. None of them are bees, which belong to a separate branch of the family tree.

Where do bees and wasps nest?

Social wasps build nests of paper, made from wood fibres “scraped from wood mixed with saliva,” says UC IPM. Yellowjackets often nest in old rodent burrows or wall cavities, in a paper envelope with a single entrance hole. Paper wasps hang small, open-celled nests under eaves.

Honey bees store honey in comb in hives or wild cavities, while bumble bees nest in the ground or in old bird nests and store honey “in a ‘pot’ rather than honey comb,” says Texas A&M. Most bee species are solitary and nest alone in single ground tunnels, says the University of Georgia.

Why do bees and wasps both matter?

Bees are vital pollinators, and wasps are natural pest controllers. Insect pollination adds more than $34 billion a year to US crops, and about 4,000 species of native wild bees help, says the US Fish and Wildlife Service. Social wasps kill “large numbers of plant-feeding insects and nuisance flies,” says UC IPM.

A 2021 review in Biological Reviews by Ryan Brock, Alessandro Cini and Seirian Sumner gathered evidence that stinging wasps work as predators, parasites, pollinators, decomposers and seed dispersers, despite their “public reputation as pointless pests.” Even the bald-faced hornet “can be considered a beneficial insect,” says Penn State, because it eats other insects and helps pollinate flowers.

Bees and wasps are also family. Genetic studies show bees branched off from within the hunting wasps around 128 million years ago, and their closest living relatives are tiny wasps that hunt thrips, small insects that sometimes gather on flowers to eat pollen (Sann et al. 2018). Researchers think that link may hint at how the ancestors of bees switched from hunting to collecting pollen. In family-tree terms, bees are a branch growing out of the wasps. Butterflies such as the monarch are pollinators too; see what monarch butterflies eat. For more insects and their relatives, browse our animal guides.

What should you do if a bee or wasp stings you?

Stay calm and move away, since swatting “may cause it to sting,” says the CDC. If a sting is left behind, scrape it out sideways, wash with soap and water, and use a cold pack. Call an ambulance (999 in the UK, 911 in the US) straight away if the lips, mouth, throat or tongue swell, or breathing becomes difficult, says the NHS.

People who know they have a severe allergy to stings should carry their prescribed adrenaline (epinephrine) auto-injector, the CDC advises.

Myths about bees and wasps

Myth: Every bee dies after it stings.

Fact: Only worker honey bees usually do, because their barbed sting stays in skin. Bumble bees can sting repeatedly (Cornell University). Why people believe it: the honey bee is the best-known bee, and its sting left behind in the skin is easy to see. Source: Zhao et al. 2015.

Myth: Wasps are pointless pests.

Fact: Wasps control crop pests and flies, pollinate some flowers and recycle dead animals (Brock et al. 2021; UC IPM). Why people believe it: the wasps we notice most are late-summer yellowjackets at our food.

Myth: A wasp always flies with its legs hanging down.

Fact: Paper wasps dangle their back legs, but European wasps hold their legs close to the body (Western Australia DPIRD). Check hair and shape instead.

Myth: A bald-faced hornet is a hornet.

Fact: It is a yellowjacket, says Penn State Extension. True hornets belong to the genus Vespa.

Test yourself

1. Which has branched hairs that trap pollen: bees or wasps?

Bees.

2. Why do worker honey bees usually die after stinging a person?

Their barbed sting lodges in the skin and tears away from the bee’s body.

3. Why do yellowjackets crowd picnics in late summer?

Their colonies stop growing and need lots of sugar, so workers look for sweet food.

So the next time a striped insect lands on your lemonade, look before you swat. Fuzzy and stocky? Probably a bee, on its way back to the flowers. Smooth and slim? A wasp, and quite possibly one that spent the summer feeding caterpillars and flies to its young.
