23 Common Wasps & Hornets in the United States (ID Guide)

What types of wasps, hornets, and yellowjackets live in the United States?

It’s no secret that these insects are the leading cause of screaming at outdoor events! Most of the species below can’t resist investigating a soda or sugary treat. 🙂

Despite their negative reputation, wasps and hornets have fascinating lives. In addition, many are beneficial because of the amount of pests they eat in your yard. They are also important pollinators!

But you do need to be careful around most types of wasps and hornets, especially if you approach their nest. They can become VERY aggressive when defending their home.

23 COMMON Wasps & Hornets in the United States:

#1. Dark Paper Wasp

  • Polistes fuscatus

Also called the Northern Paper Wasp.

wasps in the united states

  • Adults have slender bodies, pointed heads, waists connecting their abdomens and thoraxes, and antennae, which are more curved in males.
  • They are dark reddish-brown with yellow bands on their bodies, and males have more yellow markings on the front of their heads.

These wasps are common to see in the eastern United States!

Dark Paper Wasps often build nests around human homes and outbuildings as long as they can find good sources of wood fibers for construction.

Unfortunately, their proximity to humans sometimes leads to unwanted interactions. Females sometimes sting humans or domestic animals when defending their nest. They are especially aggressive during the early part of the year when the nest is full of brood, waiting to become wasps. Towards the end of the summer, when most of the wasps are adults, they are less aggressive in defending the nest.

These wasps have some interesting eating habits! The adults get most of their nutrition from flower nectar, just like bees! I spot them often on the flowers in my backyard, especially on goldenrod flowers in the fall.

However, Dark Paper Wasps also spend a lot of time catching caterpillars and other small insects. The workers chew up this prey and absorb most of the liquid. They feed the solid portion to older larvae and then regurgitate the liquid for young larvae.

While Dark Paper Wasps can be a bit intimidating, their’ insectivorous behavior actually makes them great creatures for homeowners and gardeners to have around, as they eat a lot of pests.

#2. Bald-faced Hornet

  • Dolichovespula maculata

Also called the Bald-faced Aerial Yellowjacket, Bald-faced Wasp, Bald Hornet, White-faced Hornet, Blackjacket, White-tailed Hornet, Spruce Wasp, and Bull Wasp.

hornets in the united states

  • They have black bodies with ivory markings on their faces, legs, thoraxes, and abdomens.
  • Look for three white stripes at the ends of their bodies.

Bald-faced Hornets are named for the ivory markings on their face. Despite the name, these insects aren’t true hornets. They’re actually a type of yellowjacket.

Bald-face Hornets don’t have a pleasant reputation in the United States.

They aggressively defend their nests and can sting repeatedly. But while their appearance and nests can be scary, they’re pretty handy to have around (as long as the nest isn’t close to human habitation).

First, the adults feed on nectar and help to pollinate flowers. In addition, they also kill and eat other types of yellowjackets! Sometimes, in early summer, a nest will be so full of yellowjacket remains that it will have a yellowish cast! Unless their nest is somewhere you’ll come into contact with it, it’s best to leave them be.

I’m sure you have spotted one of their nests before. They are large, papery, and football-shaped. The queen builds these nests by chewing wood material and mixing it with her saliva to make a paste.

bald faced hornet nest

Bald-faced Hornet queens usually hang their nests from shrubs or trees. Sometimes, they’ll use other spots, including rocks, buildings, and other artificial materials. The queen typically continues creating workers into the summer until the nest has 100 to 400 individuals!

#3. Eastern Yellowjacket

  • Vespula maculifrons

wasps in the united states

  • They are black with yellow markings.
  • Their first abdominal segment has a wide, black, anchor-shaped marking.
  • Cheeks have continuous yellow bands that don’t completely encircle their eyes.

Eastern Yellowjackets seem to be found in every habitat in the United States!

In urban and suburban areas, you may spot them in woodlands, parks, pastures, and lawns. They’re not picky!

And unfortunately, these wasps can deliver an incredibly painful sting. Make sure you don’t wander too close to their nests, which they aggressively defend! These nests can be huge, as queens produce up to 25,000 individuals over a season.

Another problem with Eastern Yellowjackets is their nests are typically underground, so it’s hard to spot one. The nests are often found in residential lawns and are inconveniently discovered while mowing. 🙂

eastern yellowjacket nest

Eastern Yellowjackets feed on flower nectar and fruit juices (or soda and sugar) but spend much of their time gathering food, such as insects and occasionally carrion, for the colony’s larvae. The larvae wiggle to inform nearby workers that they’re hungry, and the workers go out and capture other insects using their powerful mandibles. The workers cut up, chew the insects, then feed the paste to the larvae.

#4. European Paper Wasp

  • Polistes dominula

wasps in the united states

  • Black with prominent yellow markings.
  • They have thin waists and orange-tipped antennae.
  • Their legs dangle as they fly.

These wasps’ bright yellow and black coloration means that they’re often confused with native Eastern Yellowjackets. However, European Paper Wasps are an invasive species in the United States. Unfortunately, they are now widespread, and researchers have found that they often outcompete native paper wasps and negatively affect caterpillars like the Monarch butterfly.

One of the reasons they have spread across North America is because of their adaptability. European Paper Wasps will inhabit almost any habitat, including urban and suburban areas. They often are closely associated with humans and nest on or in human-made structures. European Paper Wasps often build nests under the eaves or attics of structures or in pipes, light fixtures, boats, grills, and mailboxes.

european paper wasp nest

These wasps are known to be fairly non-aggressive. However, they will defend their nests, and stings usually occur when humans accidentally come in contact with a nest.

European Paper Wasps are omnivores. They will catch insect larvae, caterpillars, aphids, and other soft-bodied insects that they feed the young. Adults may also feed on flower nectar.

#5. Metric Paper Wasp

  • Polistes metricus

metric paper wasps in the united states

  • They are rusty with black markings on their thoraxes and mostly black abdomens.
  • They have an ocelli (simple eye) on their head, black upper legs, and yellow lower legs.

Metric Paper Wasps in the United States tend to choose large, well-lit areas for their nests and often use sheds, barns, and under the eaves of dwellings. They prefer to build nests near ponds and other water sources as they make frequent trips to drink during the summer.

These wasps are distinct in their nesting habits. Unlike many more territorial wasps, Metric Paper Wasps will share nests with other Polistes species. They also reuse nests for multiple seasons.

Adults get some of their nutrition from flower nectar. They also collect caterpillars and other soft-bodied insects. They feed the solid portion to the larvae and consume the liquid and semi-solid for their own nutrition.

#6. Fraternal Potter Wasp

  • Eumenes fraternus

fraternal potter wasps in the united states

  • Black, shiny abdomens with ivory markings on their faces, thoraxes, and bellies.
  • They have metallic bluish-brown wings.

Fraternal Potter Wasps are solitary, docile wasps found in the United States.

The name “wasp” may bring to mind large nests of defensive, often scary insects, but these little wasps don’t come close to that reputation! The females don’t even defend the nests; they only sting when purposely touched.

After mating, females begin building the characteristic little nests that give them their name. She sculpts little pot-like structures of clay and earth, usually securing them to vegetation. Occasionally, she will attach them to houses.

fraternal potter wasp nest

Once these little pots are finished, she begins collecting prey, usually caterpillars and small soft-bodied insects. Rather than eating them herself, she paralyzes the prey and places it into the pots.

Once enough is stored, she lays an egg in the pot, suspended over the prey. Then, she seals up the pot, allowing the egg to hatch, feed, and grow. The females don’t tend to the nests after this point.

#7. Four-toothed Mason Wasp

  • Monobia quadridens

four toothed mason wasp

  • Shiny black with white angled shoulder marks, thin white bands before their waists, and thicker white bands after their waists.
  • They have black wings with a metallic luster.
  • White markings on their abdomens resemble teeth (hence the name).

Their contrasting black-and-white coloring can make these medium-sized wasps seem a little scary. At first glance, they are often confused with the more territorial Bald-faced Hornet. However, Four-toothed Mason Wasps are solitary, docile wasps in the United States.

They don’t even defend their nests! However, the females can sting if you handle them, and they’re said to have a sting comparable to a Bald-faced Hornet. Males of the species lack stingers but will jab you with the pointy end of their abdomen, which is said to feel more like a pin-prick.

Females typically build their nests in existing holes. She begins filling her nest by crawling into the tunnel’s far end and laying an egg. Then she hunts caterpillars, paralyzing them with her sting and placing them in front of the egg for the larva to eat when it hatches. When she’s satisfied with the number of caterpillars, she seals this tunnel section with two mud walls with an air pocket between them. She repeats the entire process until the tunnel is full.

These unusual mothers can choose to lay either a male or female. This is because males take less time to hatch. She places all the female eggs toward the back of the tunnel and all the males toward the front so they can hatch and leave without disturbing the female eggs.

#8. German Yellowjacket

  • Vespula germanica

Also called the European Wasp or German Wasp.

yellowjackets in the united states

  • Black and yellow with three tiny black dots on their face.
  • They have a stout body slightly wider than their head and long black antennae.

Native to Europe, these wasps are invasive in the United States.

German Yellowjackets are primarily a ground-nesting species, but they will also nest in voids in buildings and are frequently found in urban and suburban areas.

German Yellowjackets are opportunistic scavengers. They will feed on fruit, honeydew, carrion, spiders and other arthropods, human food, and garbage. This flexible diet has been a critical feature in their widespread range expansion.

german yellowjacket nest

Interestingly, the size of their colonies is somewhat dependent on climate. For example, in Australia, colonies may have 15,000 workers, while those in the British Isles may only have 6,100 to 6,500 workers.

German Yellowjackets are known to defend their nests aggressively and can sting multiple times. They will often pursue their attackers for long distances. Combined with their large colony size, these factors make them formidable opponents to predators and dangerous to humans with pre-existing health issues and allergies.

#9. European Hornet

  • Vespa crabro

hornets in the united states

  • Adults are LARGE and range from .75 in (19 mm) to 1.4 in (35 mm) long.
  • They are brown with wide yellow markings.
  • They have light-colored faces.

This species is the only true hornet (genus Vespa) found in the United States!

European Hornets were first reported in the United States in 1840 in New York and have since spread throughout much of the USA. These hornets are unusual for stinging insects; they fly and hunt during the day AND night.

Not surprisingly, their size allows them to go after larger prey than many other wasps. European Hornets will feed on bees, wasps, yellowjackets, flies, beetles, mantises, large moths, butterflies, and dragonflies. While they eat honeybees, they usually eat one or two and are not a major threat to honeybee hives.

They’re not strictly carnivores, though. European Hornets will also feed on fallen fruit, tree sap, and other sugary foods.

european hornet nest

European Hornets make intricate paper-like nests.

The lifecycle of a European Hornet begins in the spring with an overwintered, fertilized queen. She will start building a nest. Typically, these hornets select concealed, sheltered places for nests, such as barns, hollow trees, abandoned beehives, attics, and hollow walls. They cover exposed nests with a brown, papery covering. While they’re typically non-aggressive, these hornets will sting if their nest is threatened.

#10. Common Aerial Yellowjacket

  • Dolichovespula arenaria

Also called the Sandhills Hornet and Common Yellow Hornet.

yellow jackets in the united states

  • Black with yellow markings and smoky, clear wings.
  • They have stout bodies that are slightly wider than their heads.

Common Aerial Yellowjackets can adapt to various habitats in the United States. Typically, you’ll spot their papery nests on trees and shrubs, but they will sometimes build them on the side of homes in urban and suburban areas.

These wasps are formidable defenders of their nest and can sting multiple times like other yellowjackets. But this species also has another trick up its sleeve:

Common Aerial Yellowjackets can spray venom at attackers. This venom contains an alarm pheromone, which also helps alert other workers to help defend the nest.

aerial yellowjacket nest

The nest is made from saliva and chewed-up woody material turned into a paste.

These yellowjackets commonly feed high in the trees. In the spring and summer, they prey on various insects, including lacewings, lady beetles, caterpillars, spiders, flies, grasshoppers, and crickets. They will also occasionally eat young hummingbirds and carrion. Much of this protein-rich food is given to the larvae.

Later in the summer and fall, Common Aerial Yellowjackets spend more time going after sugary foods. They’re common sights feeding on fallen fruit in orchards, visiting trash cans, and hovering around sugary drinks and foods at picnics.

#11. Southern Yellowjacket

  • Vespula squamosa
Vespula squamosa. (2023, July 1). In Wikipedia.
  • Clear wings and hairless bodies.
  • They have black and yellow stripes over their entire bodies, but queens tend to be more orange.

Southern Yellowjackets are often found in close association with humans in the southern United States, building their nests in yards, parks, and roadsides. Usually, they prefer to build their nests underground, but occasionally, they will construct them inside walls.

southern yellowjacket nest

Southern Yellowjacket workers use pheromones to coordinate their attack when defending their nest. These pheromones alert the other workers of danger and tell them where to go. Each individual can sting multiple times, so encounters with these nests often result in multiple painful stings.

Throughout the summer, the colony grows and can reach up to 4,000 individuals. While most yellowjacket species have annual nests, Southern Yellowjackets often have large multi-season nests, particularly in the warm coastal areas and the southern extent of their range. In this case, the workers and original queen will survive for multiple seasons and continue expanding. The original colony typically dies out in more northern areas in the fall.

The adults typically feed on nectar from flowers and other sugary foods. They’re often the unwanted guests circling picnics and garbage cans!

#12. Guinea Paper Wasp

  • Polistes exclamans

guinea paper wasp

  • They’re typically brown with yellow markings on their heads, thoraxes, and abdomens.
  • Narrow bodies, slender waists, smoky black wings, and antennae with red, black, and yellow bands.

Guinea Paper Wasps create small, umbrella-shaped nests with open combs that face downward. To protect their open nests, they typically seek out places that are protected from the rain. Often, this results in them using human-made structures and objects. It’s not unusual to see them building nests in storage sheds, mailboxes, pipes, infrequently used grills, and under the eaves of buildings.

guinea paper wasp nest

This wasp species is unique in the United States because ALL of the female workers can reproduce. In the event a queen dies, a worker will take her place.

This raises an important question: What makes a queen different?

Scientists have found that queens have higher glucose, fructose, and trehalose levels. These compounds act as cryoprotectants, preventing ice build-up and allowing queens to survive cold temperatures.

In part due to their small, open nests, both worker and queen mortality rates are fairly high. To cope with this, Guinea Paper Wasps have developed the interesting habit of building satellite nests near their primary nest. The colony will move to a satellite nest if predators like birds or parasites destroy the primary nest.

#13. Horse’s Paper Wasp

  • Polistes major
Polistes major. (2022, July 18). In Wikipedia.
  • They may be entirely reddish brown or reddish brown with yellow markings.
  • Their coloration varies widely over subspecies.

Horse’s Paper Wasps are one of the largest wasps in the Polistes genus. This invasive species is native to Central America but has lived in the United States for decades now.

Horse’s Paper Wasps build small, umbrella-shaped nests with downward-facing open comb. They’re called paper wasps because they create these nests from saliva, chewed wood, and plant material.

Polistes major major. (2022, March 30). In Wikipedia.

Due to the open nature of their nests, these clever wasps try to tuck them into sheltered locations. You may spot them in the southern United States hanging under tree branches or building eaves, culverts, or bridges.

As they generally live in warm climates, Horse’s Paper Wasps also have special strategies to deal with the heat. Workers will alternate foraging with gathering water. They place the water droplets around the nest and fan it by rapidly vibrating their wings. This helps to cool the nest through evaporation.

They’re not particularly aggressive, but they will fearlessly guard their nests. Their relatively large size means they pack a painful sting!

#14. Hunter’s Little Paper Wasp

  • Polistes dorsalis

Hunter's Little Paper Wasp

  • V-shaped yellow markings on their heads.
  • They are usually dark brown or black.
  • Alternating dull orange, yellow, brown, and black sections on their abdomens.

As their name suggests, Hunter’s Little Paper Wasps are one of the smaller paper wasp species in the United States. You’ll often find them in open areas like meadows, yards, or flatwoods.

The nests are open, umbrella-shaped nests the queen builds from chewed-up woody material and saliva. As these nests are so vulnerable, the queen usually selects a sheltered and inconspicuous spot, like in rock piles or hollow logs. In suburban and urban areas, the queens may build under the lower border of roofs or in dense shrubs.

Polistes dorsalis. (2023, July 31). In Wikipedia.

Adults feed on nectar and other sweet substances, including the honeydew from a fungus that affects grasses and cereals, including rye called ergot. Unfortunately, their feeding behavior also makes them vectors for this fungus, which can be detrimental to crops.

#15. Fine-backed Red Paper Wasp

  • Polistes Carolina

fine backed red paper wasp polistes carolina

  • They have black wings.
  • Reddish-brown with fine ridging on their first abdominal segment.

Fine-backed Red Paper Wasps live in woodlands or urban and suburban areas but seek protected locations for their nests. They often build nests in hollow trees in forests, but they usually use human-made structures for shelter near human development.

polistes carolina nest

The umbrella-shaped nest is made of compressed, chewed wood and saliva and features an open comb.

After constructing a nest, the queen will lay eggs and tend them until they become the colony’s first workers. These workers are non-reproductive females that take over expanding and defending the nest, tending the larvae, and foraging. If the primary queen dies, a worker may step up and take her place.

These wasps sometimes seem like a nuisance to homeowners in the United States, but they can be very helpful to have around. To feed the larvae, workers prey on various garden pests, including beetles, cicadas, and caterpillars. They also feed on flower nectar and pollinate some of the plants they visit.

#16. Western Yellowjacket

  • Vespula pensylvanica
Vespula pensylvanica. (2023, June 1). In Wikipedia.
  • Females (workers and queens) have a yellow loop around each eye.
  • They are yellow with black markings and no hairs.

Western Yellowjackets are habitat generalists, building their nests in gardens, prairies, open forests, urban areas, parks, and meadows. Typically, they construct their nests in the ground, often using old rodent burrows or other existing holes to get started. Occasionally, they’ll nest in voids in the walls of houses and other structures.

These impressive nests are started in the spring by a queen who mated the previous fall and overwintered in a sheltered spot. The queen begins a small nest and lays eggs, caring for the larvae and foraging for materials until the first four to seven workers have emerged. After this point, the queen remains in the nest, laying eggs.

You may spot these creatures feeding on carrion or buzzing around picnic tables, trash cans, and fallen fruit. Western Yellowjackets are incredibly common to find living around people.

And unfortunately, these wasps can deliver an incredibly painful sting. Make sure you don’t wander too close to their nests, which they aggressively defend!

Another problem with Western Yellowjackets is their nests are typically underground, so it’s hard to spot one. These nests are often found in residential lawns and are inconveniently discovered while mowing the lawn. 🙂

#17. Golden Paper Wasp

  • Polistes aurifer

golden paper wasp

  • Their coloration varies widely with location.
  • Northern individuals are often predominantly black with some golden coloring.
  • Southern individuals often have an almost entirely golden abdomen.

These wasps get their name from their unusual coloration, a softer golden yellow rather than the bright yellow of many other wasp species. Their scientific name, “aurifer,” also alludes to this coloration and is Latin for “gold-bearer.”

Queens start new nests in the late winter or spring. These wasps generally seek out high, sheltered locations to build.

As the name “paper wasp” suggests, the queens construct a nest from a paper-like material they make with saliva and wood fiber. The umbrella-shaped nests they create have open combs on the bottom.

The queens use the nest to hatch workers, which will help guard the nest and hatch more colony members. You may spot these workers visiting flowers, feeding on the nectar, or grabbing insects off plants, which they use to feed the colony’s larvae.

#18. Ringed Paper Wasp

  • Polistes annularis

Also called the Jack Spaniard Wasp.

Polistes annularis. (2023, June 24). In Wikipedia.
  • Black abdomens with a single yellow ring at the end of their first body segment.
  • They have rust-red faces and bodies, yellowish legs, and yellow antennae tips.

Ringed Paper Wasps have an extensive range, but they’re almost always found under overhangs along bodies of water, especially river banks. They find sheltered places like under the branches of trees and shrubs, cliff overhangs, or occasionally building eaves to build their nests.

If you find one of these wasps in the United States, it’s likely you’ll find more.

That’s because Winged Paper Wasps tend to group their nests in large colonies called aggregations. The nests are also notable for their size. Ringed Paper Wasps’ nests are much larger than those of other paper wasps and often have about 500 cells.

These nests have open combs and look a bit umbrella-shaped. The queens or foundresses build the nests in the spring, usually near the nest they were born in, though they never reuse nests. Sometimes, a single foundress will build a nest, while other times, as many as 22 foundresses will work together on a nest. Usually, these associations of wasps all came from the same nest the previous season.

#19. Yellow Paper Wasp

  • Polistes flavus
Polistes flavus. (2022, July 18). In Wikipedia.
  • They are almost entirely yellow.
  • Jade green eyes and smoky dark wings.

These large wasps are among the most easily recognized wasp species in the United States due to their yellow coloration.

Their scientific name also reflects this: flavus is Latin for yellow.

The queens or foundresses of this species construct their nests in the spring using a mixture of their saliva and plant fibers. They build with surprising precision and can create cell walls that all have an exact thickness.

yellow paper wasp nest

Sometimes, the foundresses work solo on these nests, while other times, sisters from the previous season’s nest will work together. There is always one dominant queen, though, and she’s the one that will lay eggs in the nest. 

#20. Alaska Yellowjacket

  • Vespula alascensis

Also called the Common Yellowjacket.

alaska yellowjacket

  • Black and yellow bodies with yellow legs.
  • Yellow eyerings, which have dark interruptions on the tops and behind the eyes.
  • They have broad black bands leading from the base of their antennae to the tops of their heads.

Our knowledge of this species has taken some interesting twists! The Alaska Yellowjacket was first described and named by American entomologist and paleontologist Alpheus Spring Packard Jr. in 1870. Unfortunately, the information he gathered on this species was lost just a year later in the Great Chicago Fire of 1871!

After this point, the Alaska Yellowjacket (Vespula alascensis) was treated as a synonym for the similar-looking European Wasp (Vespula vulgaris). The Alaska Yellowjacket wasn’t recognized as a separate species until 2010!

Like many yellowjacket species in the United States, they typically build underground nests, which may help shelter them from hot or cold temperatures. They often build nests around areas of human habitation.

The adults are attracted to all things sweet, which is one of the reasons they’re often closely associated with people. Human food and garbage make for excellent food sources in addition to the nectar they gather from flowers.

#21. Apache Paper Wasp

  • Polistes apachus

Also called the Texas Paper Wasp or Southwestern Texas Paper Wasp.

apache paper wasp

  • They have dull orange-brown antennae.
  • Primarily golden brown with alternating stripes of golden brown and yellow on their abdomens.

Apache Paper Wasps are most commonly found in the United States in vineyards and orchards. They will also inhabit urban areas. If you observe them carefully, you’ll find they make frequent trips to drink water. It’s not uncommon to see Apache Paper Wasps using surface tension to stand on a puddle’s surface to drink.

Like many paper wasps, Apache Paper Wasps nests look a bit like an umbrella and have an open, downward-facing comb. By the end of the season, one nest may have up to 320 cells.

apache paper wasp nest

Their nests are started by overwintered, fertilized queens. Sometimes, these queens will work independently, while other times, other queens will help out, but these helpful females don’t always stay permanently. They often leave after construction to work on a nest of their own.

Since they hunt caterpillars, Apache Paper Wasps can be helpful to farmers as they provide some pest control. However, they have a painful sting, and their preference for vineyards and orchards has led to them sometimes becoming a nuisance.

#22. Mexican Paper Wasp

  • Mischocyttarus mexicanus
Mischocyttarus mexicanus. (2023, March 30). In Wikipedia.
  • They are primarily reddish brown or dark brown.
  • Thin yellow stripes on their abdomens.
  • They have rust-colored antennae.

Since Mexican Paper Wasps live in the warm climates of the United States, they can start new nests at any time of the year.

These wasps have two strategies for nest building. Sometimes, each queen will build her own nest, while sometimes, up to 20 queens will work together to create a nest. In these cases, the associated queens typically all originated from one nest.

The nests they build are open, paper combs made from a mixture of saliva and wood fiber. The queens often choose to attach these nests to saw palmetto or cabbage palm leaves, but they will also build in Spanish moss, oak trees, and buildings. These crafty wasps also prefer to build nests that face the east so that the sun warms them in the morning.

mexican paper wasp nest

Mexican Paper Wasps may have a less strict social structure than other paper wasps. There’s often more than one queen per nest, and many of the females in a nest are reproductively viable. If a queen dies, she’s usually replaced within a week, and switching nests is common. Colonies will accept wasps from other colonies as long as they’re young but generally reject older individuals.

#23. Western Paper Wasp

  • Mischocyttarus flavitarsis
Mischocyttarus flavitarsis. (2023, May 18). In Wikipedia.
  • Slender bodies with long trailing legs.
  • They’re generally reddish-brown with some black and yellow markings, but their coloration varies with population.
  • Yellow-brown wings.

Western Paper Wasps live in the United States in forests, suburban neighborhoods, and urban areas near a river or stream. They move along these river and stream openings when they’re out foraging for insects and nectar and collecting fibers to build their nest. They also gather water and take droplets back to the nest to cool it during hot weather.

These wasps may look frightening, but they’re not very aggressive. If Western Paper Wasps feel threatened, they’ll stand on their back and middle legs and point their antennae forward to warn predators. They may also make a loud buzzing noise with their wings as a further warning. While they can and may sting to defend their nests, Western Paper Wasps have the interesting habit of ramming predators with their heads rather than stinging.

Unfortunately for the queens, having their colony taken over is fairly common in this species. The queen will fight the wasp attempting to take her place, and they will bite and try to sting each other. Sometimes, if a foreign wasp takes over, the queen may flee with her daughters following her to build a new nest.
