Wasp species like the common wasp and yellow jacket can cause confusion due to their similarities in appearance and behavior. However, understanding the key differences between these two types of wasps can help you identify them and respond appropriately to their presence.
The common wasp (also known as paper wasps) can vary in color, including yellow, brown, red, and black. Their distinguishing feature is their slender body, measuring about 3/4 inches in length. Paper wasps build a single open-faced comb nest, usually made of paper, often found attached to building eaves. These wasps are beneficial as they are predators, feeding on flies, caterpillars, and spiders, thus controlling pest populations. However, when threatened, they can be aggressive and sting in defense of their nest.
On the other hand, yellow jackets are more stout and typically banded in black and yellow. Their nests are usually found underground, and locating their nests can be difficult, having just a single entrance. Yellow jackets can also become pests when scavenging for food, especially during picnics or when they find exposed trash cans. They are known to be more aggressive than paper wasps and can sting multiple times, which can be hazardous for those with allergies or sensitive skin.
In summary, common wasps and yellow jackets have unique features and behaviors that can help in differentiating them. Being aware of their distinctions can be useful in determining whether they are beneficial insects to have around or a potential nuisance that needs to be managed.
Common Wasp Vs Yellow Jacket
Identification and Appearance
Common Wasp
- Slender body
- Thin waist
- Smooth and shiny appearance
- Legs not dangling during flight
Example: Paper wasps
Yellow Jacket
- Shorter, thicker body
- Segmented bodies
- Legs dangling during flight
- Aggressive in nature
Example: Vespula germanica
Size and Body Structure
| Common Wasp | Yellow Jacket | |
|---|---|---|
| Body Structure | Slender body with a narrow waist | Shorter, thicker bodies with segments |
| Size | Varies from 1/2 inch to nearly 1 inch | Approximately 1/2 inch |
Color and Markings
Common Wasp
- Black and yellow or cream bands
- May have additional colors, like red or brown
Yellow Jacket
- Predominantly yellow with black markings
Both common wasps and yellow jackets are insect predators, feeding on various insects. While they share similar feeding habits, common wasps tend to be more docile compared to aggressive yellow jackets, which are notorious for stinging when their nests are threatened.
Common wasps may build their nests above ground, in sheltered areas, whereas yellow jackets create ground nests, with a single entrance that serves as both an entry and exit point for the insects.
Habitat and Nesting
Nest Types and Locations
Common Wasps:
- Build umbrella-shaped nests
- Commonly found in trees, shrubs, and man-made structures
Yellow Jackets:
- Construct underground nests
- Found in soil, tree logs, and occasionally in wall cavities of buildings
Examples of common wasp nest locations include attics, garden sheds, and under the eaves of houses. On the other hand, yellow jacket nests are commonly found in rodent burrows, tree stumps, and rock wall crevices.
Underground and Above Ground Nesting
Underground Nesting:
- Mainly associated with yellow jackets
- Old rodent burrows, shallow holes in the ground, or tree stumps are common locations
Above Ground Nesting:
- Commonly seen in other wasps, such as paper wasps and mud daubers
- Nests built using material like tree sap, chewed wood fibers, or mud
Both common wasps and yellow jackets live in social colonies in the northern hemisphere, consisting of a mated queen, her male drones, and worker wasps.
Comparison Table
| Feature | Common Wasp | Yellow Jacket |
|---|---|---|
| Nest Type | Umbrella-shaped, made of chewed wood fibers | Underground, built with a paper-like material |
| Nest Location | Trees, shrubs, man-made structures | Soil, tree logs, wall cavities |
| Habitat | Northern hemisphere | Northern hemisphere |
| Interaction with Humans | Generally peaceful unless threatened | Can be more aggressive, especially when defending the nest |
Characteristics of common wasp nests:
- Umbrella-shaped
- Above ground
- Made of chewed wood fibers
Characteristics of yellow jacket nests:
- Underground or in wall cavities
- Made of a paper-like material
- Can house thousands of individuals
While both types of wasps can be beneficial for controlling other insect populations, caution should be taken when dealing with their nests, as they will sting when they feel threatened.
Behavior and Diet
Feeding Habits
Both common wasps and yellowjackets have similar feeding habits, requiring a mix of protein and sugar sources. Typical food sources include:
- Protein: Predominantly for larvae, obtained from insects, flies, and spiders.
- Sugar: Mainly for adults, obtained from plant nectar, fruits, and tree sap.
Nectar feeding by these wasps also contributes to pollination.
Predatory and Defensive Behavior
Common wasps, such as paper wasps, are generally less aggressive than yellowjackets. However, when their nest is threatened, up to 75 paper wasps may sting in defense. In contrast, yellowjackets can become aggressive picnic pests when foraging for food.
| Feature | Common Wasps (e.g., Paper Wasps) | Yellowjackets |
|---|---|---|
| Aggressiveness | Less aggressive, sting when nest threatened | More aggressive, can be picnic pests |
| Nest | Paper nest, usually attached to eaves | Can build ground or aerial nests |
| Color | Various (e.g., yellow, brown, red, black) | Banded in black and yellow/cream tones |
| Size | Slender, up to 3/4 inches long | Smaller, up to 1/2 inch long |
Both common wasps and yellowjackets can cause painful stings and, in some cases, severe allergic reactions in humans. While they can be a nuisance, it’s important to remember that they are beneficial insects, acting as predators of pest insects and also performing pollination.
Life Cycle and Reproduction
Colony Development
In wasps and yellowjackets, colony development begins with the queen building a nest to lay eggs. Here’s a comparison of their respective nests:
| Wasp Nest | Yellowjacket Nest | |
|---|---|---|
| Size | Smaller, open comb | Larger, enclosed |
| Shape | Often umbrella-shaped | Rounded or multi-layered |
| Location | Attached to building eaves | Underground or hidden in buildings |
Both wasp and yellowjacket colonies consist of a queen, workers, and males, but wasps generally have smaller colony sizes. The queen is responsible for egg-laying, while the workers focus on collecting food, caring for larvae, and defending the colony.
Mating and New Queen Production
Mating occurs in the fall, where males and new queens are produced. The new queens will mate with males and then find a safe place to overwinter. In spring, the mated queens will begin new colonies.
Here are some species of wasps and yellowjackets:
- Vespula alascensis: a species of yellowjacket commonly found in the northwestern United States
- Vespula squamosa: the southern yellowjacket, native to the southeastern United States
- Bald-faced hornets: a type of wasp belonging to the Vespidae family, known for their black and white coloration
Aside from some physical differences, their life cycles are quite similar. Some key features of the wasp and yellowjacket reproduction process include:
- Mated queens overwintering
- New colonies started yearly
- Short colony life spans
Comparisons and Differences
Comparison with Other Wasp Species
- Common wasps are typically slender, measuring around 3/4 inches in length, and have various colors such as yellow, brown, red, and black1. Their nests are open-faced combs, often attached to building eaves1.
- Yellowjackets resemble bees in size and have black and yellow bands on their abdomens2. They usually build paper nests underground2. Their faces are yellow or white2.
Comparison Table
| Feature | Common Wasp | Yellowjacket |
|---|---|---|
| Size | Slender, 3/4 inches long | Bee-sized |
| Colors | Yellow, brown, red, and/or black1 | Black and yellow bands2 |
| Nest Type | Open-faced combs1 | Paper nests underground2 |
| Face Color | – | Yellow or white2 |
European Wasp
The European Wasp (Vespula germanica) is a common vespid wasp found in the northern hemisphere3. It scavenges for meat and sweets, often becoming a nuisance at picnics and campgrounds3.
Characteristics
Vespid Wasps
Vespid Wasps, also known as Vespidae, include both common wasps and yellowjackets3. These wasps can be beneficial in controlling pests due to their predatory nature3. However, they can also become a hazard if their stings present a risk to humans3.
Pros
- Predatory nature helps control pests3
Cons
- Can become a hazard due to stinging risks3

The time of year these were found would point to them probably being queens. Everybody else in the hive should be dead by now.
Thanks so much for additional confirmation.
