Yellow jackets are a species of wasp that are common throughout the United States. These stinging insects are known for their bright yellow and black striped bodies and can be identified by a number of physical characteristics.

One of the most distinctive features of the yellow jacket is their narrow “waist.” The area between the thorax and abdomen is relatively thin and gives the insect a distinctive hourglass shape. This feature is especially noticeable when the wasp is in flight and can help to differentiate it from other stinging insects.

Yellow jackets are also known for their large, broad heads and powerful mandibles. These features are used by the insects to capture and subdue prey, as yellow jackets are known to feed on other insects, as well as nectar and fruit juices.

Overall, the yellow jacket is a striking and easily recognizable insect that should be approached with caution due to their potentially painful stings. Understanding the physical characteristics of these insects can help you to identify them in the wild and take appropriate precautions to avoid an unwanted encounter.

Physical Appearance

Size and Shape

Yellow jackets are small, predatory wasps that belong to the genus Vespula. They are about 10 to 16 millimeters long and have slender bodies with elongated abdomens. Their wings are transparent and they have six long legs. The queen yellow jacket is larger than the workers and males.


As their name suggests, yellow jackets have a distinctive yellow and black coloration. The head and thorax are black, while the abdomen is yellow with black stripes. The brighter markings of yellow jackets distinguish them from bees, which are typically covered in hair and have less vivid markings.



Yellow jackets are known for their aggressive behavior and stinging ability. They are social insects, living in large colonies that can contain thousands of individuals. Yellow jackets are active throughout the summer and early fall, with workers foraging for food and caring for the larvae. If they feel threatened or their nest is disturbed, they will defend themselves vigorously by stinging repeatedly.


Yellow jackets are a type of wasp that are black and yellow in color. They are usually between 10-16 mm in length and have a distinct waist between the thorax and abdomen. They have two pairs of wings and mandibles for biting and chewing.

Their bodies are covered in hairs, which can make them appear fuzzy or velvety. This helps them collect pollen and defend their nests. Unlike bees, yellow jackets do not have barbed stingers, which means they can sting multiple times.

Distinctive Features

  • Black and yellow striped body
  • Slender, elongated body with a distinct waist
  • Two pairs of wings and mandibles for biting and chewing


Yellow jackets are social insects and live in large colonies. Their nests are typically located underground, in hollow trees, or in structures such as buildings or walls. They are attracted to sugary substances and often become aggressive around food sources.

If you spot a yellow jacket, it’s best to stay away and call a professional if you need to have it removed. Their stings can be painful and potentially dangerous for those with allergies.

Color Patterns

Yellow jackets are best known for their distinctive black and yellow striped pattern. This pattern is a warning sign to potential predators that they are armed with a powerful sting, and should be approached with caution.

However, not all yellow jackets have the classic black and yellow striped pattern. Some species have a black and white striped pattern, while others have a combination of yellow and orange stripes. Additionally, some yellow jackets have more muted coloration patterns of brown or white.

Color patterns can also vary across different parts of their body. For example, the head of a yellow jacket may have less yellow coloring than the rest of its body. This can make identifying different species of yellow jackets more challenging.

It is important to note that color patterns alone are not enough to identify a yellow jacket species with certainty. Other physical characteristics, such as body shape and size, are also important factors to consider.

  • Yellow jackets have a reputation for being aggressive. However, it is important to remember that they only attack if they feel threatened.
  • If you are concerned about a yellow jacket infestation on your property, it is best to contact a pest control professional for assistance.

Body Features

Size and Shape

The body of a yellow jacket is about ½ inch to ⅝ inch in length. They have a slender waist and a wide head. Their body shape is similar to that of a wasp or a hornet. Yellow jackets also have smooth skin on their bodies, which is usually black with bright yellow markings on their head, thorax and abdomen.


One of the most prominent features of yellow jackets is their stingers. Yellow jackets have a smooth stinger, which is used to sting their prey or people when they feel threatened. This stinger is found on the end of their abdomen and is used to inject venom into their target. Unlike bees, yellow jackets do not lose their stingers after using them, which means they can cause multiple stings.


Yellow jackets have four wings which are clear and slightly yellowish in color. Their wings are narrow and elongated, which helps them to fly quickly and maneuver easily. Yellow jackets can fly very fast, and they can change direction quickly, making them difficult to catch.

Legs and Antennae

Yellow jackets have six legs which are attached to their thorax. Their legs are covered with tiny hairs which help them to grip onto surfaces and carry food. They also have two long antennae which help them to sense their environment and locate food sources. Their antennae are black and yellow in color, similar to their bodies.


Yellow jackets are aptly named for their bright yellow coloring. Their bodies are black with yellow markings. Different species of yellow jackets may have different patterns of markings on their bodies, but they all share the black and yellow coloration. This coloring is thought to act as a warning to predators, as it indicates the presence of venomous stingers and aggressive behavior.

Yellow jackets are small to medium-sized wasps, typically measuring less than an inch in length. However, their size can vary depending on the species. Some species may be as small as a few millimeters, while others can grow up to 2 inches long.

Their bodies are typically black and yellow, with visible stripes on their abdomens. The stripes can vary in thickness and color, depending on the species.

Their wings are transparent and typically fold longitudinally when at rest. They have six legs, which are typically black or dark brown in color.

Overall, yellow jackets are compact and sleek, with a relatively smooth body shape that allows them to move smoothly through the air.



The yellow jacket has four wings that are transparent with black veins. The wingspan of the queen yellow jacket can reach up to 2.5 cm long.

The wings of the yellow jacket are thin and membranous, enabling them to fly quickly and maneuver easily through the air.


The wings of the yellow jacket allow them to fly from one location to another in search of food and shelter. They can also use their wings to hover in one spot while searching for food or observing their surroundings.

In addition to flying, the wings of the yellow jacket are also used for communication. They use their wings to create vibrations that other yellow jackets can sense. This is particularly useful for coordinating their activities, such as when they are attacking a predator or foraging for food.

Overall, the wings of the yellow jacket are essential for their survival and play a crucial role in their everyday life.

As always, it’s important to give yellow jackets their space and avoid disturbing their nests.


What are stingers?

Stingers are the sharp, pointed organs found at the end of the abdomen of some insects, including yellow jackets. The stinger is a modified egg-laying structure called an ovipositor, and it is used for defense.

How do stingers work?

When an insect with a stinger feels threatened, it can use the stinger to inject venom into the skin of its attacker. The venom causes pain, swelling, and other allergic reactions in humans. In some cases, stings from yellow jackets can be life-threatening, especially if a person is allergic.

What should you do if you get stung by a yellow jacket?

If you get stung by a yellow jacket, you should remove the stinger as soon as possible with tweezers or by scraping it off with a credit card. Wash the area with soap and water and apply a cold compress to reduce swelling. If you have a severe reaction, such as difficulty breathing or swelling of the face, seek immediate medical attention.


Yellow jackets can be found in most parts of the world. They prefer living in warm and dry environments. These insects are very adaptable and can create their nests in various places, including underground, in trees, in wall voids, and under eaves.

Yellow jackets are known to build underground nests in abandoned rodent burrows, which can be dangerous for people and their pets. They also build aerial nests that are attached to trees, shrubs, and buildings.

It is essential to be cautious around yellow jacket nests, as they are very protective of their territory and can attack anyone who gets too close. Additionally, yellow jackets can be a nuisance at outdoor gatherings, picnics, and barbecues.

Yellow jackets are also known to scavenge for food and are attracted to sweet smells. They can be found near garbage cans, picnic tables, and outdoor food stands.
