Yellowjacket vs Wasp: What’s the Difference?

Quick answer: A yellowjacket is a type of wasp, so the two are not opposites. “Wasp” is the big group, and yellowjackets are one stocky, black-and-yellow, often aggressive social kind within it. Other wasps, such as paper wasps and mud daubers, look and behave differently.

Yellowjacket vs wasp is a confusing comparison because it sounds like a choice between two different insects, when one is really part of the other. People also lump every buzzing, stinging insect together, so the names get swapped. This guide shows how the terms relate, how to tell common wasps apart and what each one tends to do.

What is a wasp?

A wasp is any member of a large group of stinging insects that are not bees or ants. The term covers thousands of species, so it works like “bird” does for sparrows and eagles.

Many wasps are solitary, meaning each female builds her own nest or hunts alone, and they rarely bother people. Others are social, living in colonies with a queen and workers. Social wasps include paper wasps, hornets and yellowjackets. Wasps also differ from honeybees, which are fuzzier and rounder and collect pollen, while most wasps have smooth, narrow bodies.

What is a yellowjacket?

A yellowjacket is a social wasp with a stocky body, bold black-and-yellow markings and a narrow “waist.” Most are about half an inch long, with short legs that stay tucked up in flight.

They build enclosed paper nests, often underground in old rodent burrows, but sometimes inside wall gaps or hollow logs. A colony can grow large by late summer. Yellowjackets feed on insects and also on sweet drinks and meat, which is why they show up at picnics and around trash cans. Every yellowjacket is a wasp, but only some wasps are yellowjackets.

Yellowjacket vs wasp: how can you tell them apart?

Look at the body shape, legs and nest. A yellowjacket is compact with a thick, tidy look, while many other wasps are longer, thinner and more loosely built.

Paper wasps are the usual lookalike. They have slender bodies, longer legs that dangle in flight, and brownish or reddish tones with yellow markings. Their nests are open, umbrella-shaped combs with visible cells, usually hanging under eaves or branches. A yellowjacket nest is a closed paper ball with a small entrance, often hidden in the ground. Solitary wasps, such as mud daubers, are thin-waisted and build small mud tubes rather than large colonies.

Are yellowjackets more aggressive than other wasps?

Yellowjackets are often more aggressive than paper wasps and far more than solitary wasps, especially near their nest and in late summer. By then colonies are at their peak size, and workers hunt for food more actively around people.

Like other wasps, they have a smooth stinger, so they can sting more than once. A sting is painful, and some people are allergic. Anyone with trouble breathing, swelling of the face or throat, or dizziness after a sting needs emergency care right away.

Is a hornet a wasp or a yellowjacket?

A hornet is a wasp, and in some cases it is also a yellowjacket. True hornets, such as the European hornet, belong to the genus Vespa and are larger than yellowjackets. The bald-faced hornet is an exception: despite the name, it is a type of yellowjacket with a black-and-white face.

How can you remember which one to use?

Think of “wasp” as the family name and “yellowjacket” as one member. If you know the exact kind, use the specific name. If you do not, “wasp” is the safe word.

Memory tricks

  • Group and member. Wasp is the group, and yellowjacket is one member of it.
  • Jacket = compact and bold. A yellowjacket looks like it wears a snug black-and-yellow jacket.
  • Legs and nest. Dangling legs and an open umbrella nest suggest a paper wasp, while short legs and a hidden closed nest suggest a yellowjacket.

Common mistakes with yellowjackets and wasps

  • Yellowjackets are not wasps. Yellowjackets are a type of wasp.
  • A yellowjacket is a kind of bee. A yellowjacket is a wasp, not a bee.
  • All wasps live in big, aggressive colonies. Many wasps are solitary and rarely sting people.
  • The bald-faced hornet is a true hornet. The bald-faced hornet is actually a type of yellowjacket.
  • Yellowjackets die after they sting. Yellowjackets can sting more than once.
