24 Types of Wasps in North America: From Yellowjackets to Giant Wood Wasps
October 24, 2026
Most people picture a single angry insect when they hear the word “wasp,” but the reality is far stranger and more interesting. North America is home to dozens of wasp species, and the types of wasps in North America range from picnic-raiding yellowjackets to shy, solitary hunters that never bother people at all. Some build papery nests the size of a basketball, while others tunnel alone into sandy soil or paralyze spiders for their young.
This guide walks through 24 wasps found across the continent, grouped by family and behavior, so readers can tell a harmless mud dauber from a defensive hornet before getting too close. Each profile covers the markings, nesting habits, and quirks that set the species apart.
Pro Tip: Most wasp stings happen when a nest is disturbed, not from random encounters. Watching where you step near woodpiles, eaves, and ground burrows in late summer avoids the vast majority of incidents.
1. Yellowjackets (Genus Vespula)
The genus Vespula contains the black-and-yellow wasps most Americans think of first, including familiar species like the eastern, western, southern, and non-native German yellowjacket. According to the Missouri Department of Conservation, two native Vespula species occur statewide in Missouri alone, a pattern that repeats across much of the eastern and central United States.
Vespula wasps are almost always ground nesters, often taking over abandoned rodent burrows and building papery combs underground. Wikipedia notes that all female yellowjackets are capable of stinging, and colonies defend their nests aggressively once disturbed. These wasps are also important predators of other insects, which keeps them from being purely a nuisance despite their reputation.
Gardeners dealing with a broader mix of stinging and biting insects in their region can compare notes with a related guide to wasps found in Virginia, where several Vespula species overlap with paper wasps and hornets.
2. Yellowjackets (Genus Dolichovespula)
The second yellowjacket genus, Dolichovespula, builds its nests above ground rather than in burrows, favoring tree branches, shrubs, and building eaves. Dolichovespula is widely distributed across the North American continent, with species ranging from the familiar bald-faced hornet to the common aerial yellowjacket.
Colonies in this genus tend to be smaller than their ground-nesting Vespula relatives, and workers often hunt live insects such as flies and caterpillars rather than scavenging for human food. That hunting behavior makes most Dolichovespula species less likely to show up at a backyard barbecue, even though their aerial nests can be impressively large by late summer.
3. Eastern Yellowjacket
The eastern yellowjacket (Vespula maculifrons) ranges across the eastern half of the country and is one of the most frequently encountered social wasps in the region. Although most of its nests are subterranean, it is often considered a pest because it nests in recreational areas and buildings.
Workers measure roughly 0.3 to 0.7 inches long and show the classic black-and-yellow banding, with queens slightly larger than the workers they oversee. These wasps have a habit of investigating open soda cans and sweet drinks, which is how many backyard stings happen, since a person may not notice a wasp has crawled inside until it is too late.

4. Western Yellowjacket
West of the Rockies, the western yellowjacket (Vespula pensylvanica) takes over as the dominant ground-nesting species, often colonizing old rodent burrows into large underground colonies. Western yellowjackets are responsible for the majority of late-summer sting incidents at picnics, campgrounds, and backyards throughout California, Oregon, Washington, and the Intermountain West.
Workers are about half an inch long and share the typical black-and-yellow pattern, but one useful field mark is a complete yellow ring around each eye, which many similar-looking species lack. Colonies can swell dramatically by August and September as food becomes scarce elsewhere, which is exactly when most human encounters occur.
5. Common Aerial Yellowjacket
The common aerial yellowjacket (Dolichovespula arenaria), also known regionally as the yellow hornet or sandhills hornet, builds hanging paper nests in trees, shrubs, and under roof eaves rather than underground. It is widely distributed across the North American continent, and unlike many of its ground-nesting cousins, it is rarely drawn to human food.
These wasps forage almost exclusively for live prey, including grasshoppers, leafhoppers, and small spiders, which makes them genuinely helpful in gardens despite their intimidating size. Colonies that establish themselves in trees or on structures far from foot traffic typically go unnoticed all season, since the wasps have little interest in picnics or garbage cans.
Anyone comparing stinging insects across colder climates may want to check a related breakdown of insects found in Canada, since aerial yellowjackets extend well into the country’s southern provinces.
| Wasp Group | Nest Style | Typical Colony Size | Aggression Level |
|---|---|---|---|
| Yellowjackets | Social, ground or wall voids | 1,000–5,000+ | High |
| Hornets | Social, aerial or cavity | 200–700 | Moderate to High |
| Paper Wasps | Social, open-umbrella | 20–200 | Moderate |
| Mud Daubers & Diggers | Solitary | 1 (individual) | Low |
This pattern comes from pest-identification data showing that colony size and aggression tend to scale together across wasp groups, which is why the social species covered in the next few sections draw far more attention than the solitary hunters later in this guide.
6. Northern Paper Wasp
The northern paper wasp (Polistes fuscatus) is one of the most recognizable open-nest wasps in the eastern and midwestern United States, building the familiar umbrella-shaped combs under eaves and porch rails. These wasps have reddish-brown bodies marked with yellow bands and noticeably long, dangling legs compared to the stockier yellowjackets.
Colonies are led by a dominant queen who maintains order through postures and behavioral cues rather than chemical signals alone, a social structure that researchers have studied extensively in this genus. Northern paper wasps are generally not aggressive away from the nest and will often tolerate close observation, though they defend an active nest vigorously if it is bumped or sprayed with water.
For readers curious how paper wasps fit into a wider urban insect community, a regional survey of insects found in New York covers several species that share habitat with this wasp.
7. European Paper Wasp
Introduced from Europe and now widespread across the continent, the European paper wasp (Polistes dominula) is often mistaken for a yellowjacket at a glance because of its bold black-and-yellow pattern. The giveaway is its orange antennae, a feature native paper wasps do not share, along with the same slender, long-legged build typical of the genus.
This species nests almost anywhere with a sheltered ledge, including mailboxes, grill covers, and window frames, which brings it into contact with people more often than most native paper wasps. It is generally less defensive than a yellowjacket, but a nest built directly over a doorway or in frequently used outdoor furniture can still deliver a nasty surprise.
8. Guinea Paper Wasp
The Guinea paper wasp (Polistes exclamans) is common across the southern and south-central United States, where its reddish-brown body and slender build mirror other members of the genus. It builds smaller open-comb nests than the northern paper wasp, often tucking them into shrubs, fence posts, or the undersides of outdoor structures.
Colonies here tend to be short-lived compared to true social hornets, usually dying back each winter while a handful of overwintering queens restart new nests the following spring. This species plays a useful role in pest control by hunting caterpillars and other soft-bodied insects to feed its larvae.
Readers in warmer climates can find more regional context in a guide to insects found in Texas, where Guinea paper wasps are a familiar backyard sight through much of the growing season.
9. Bald-Faced Hornet
Despite the name, the bald-faced hornet (Dolichovespula maculata) is not a true hornet at all. Its scientific name reveals what this wasp really is: a yellowjacket, since true hornets belong to the genus Vespa. The confusion is understandable given its size and the large, football-shaped aerial nests it builds in trees and on structures.
Identification is straightforward thanks to its black-and-white coloring, a pattern unique among North American social wasps. It is one of seven to eight aerial yellowjacket species in North America and is native and widespread. Colonies can become quite defensive once a nest reaches full size in late summer, so removal is best left to professionals when a nest forms near a doorway or walkway.
Homeowners dealing with mixed stinging-insect activity around the yard may also want to review a dedicated guide to wasps in Minnesota, where bald-faced hornets are especially common in wooded suburbs.
10. European Hornet
The European hornet (Vespa crabro) holds a unique title among North American wasps. It is the most commonly encountered species and the only true hornet established on the continent, having been introduced in the 1800s and now settled throughout much of the eastern United States.
At up to 1.4 inches long, this is a genuinely large insect, noticeably bulkier than any yellowjacket and marked with brownish-red tones rather than bright yellow. One behavioral quirk sets it apart from almost every other wasp on this list: it is active at night and commonly drawn to porch lights, a habit documented by regional extension resources covering wasp behavior in the southeastern states.
European hornets nest in hollow trees, wall voids, and occasionally attics, and while their size can be alarming, they are generally less aggressive away from the nest than smaller yellowjacket species.
11. Cicada Killer Wasp
Few solitary wasps inspire more double-takes than the cicada killer (Sphecius speciosus), which can reach up to 2 inches in length. Its black or brown body with yellow abdominal bands and transparent, amber-tinted wings make it easy to mistake for a yellowjacket or hornet at a glance, despite the enormous size difference.
Female cicada killers dig burrows in sandy or loose soil, sometimes in large aggregations across lawns and golf courses, then hunt cicadas to paralyze and drag back underground as food for their larvae. Males patrol territory aggressively but lack the ability to sting at all, and females rarely sting people unless physically grabbed, making this intimidating-looking wasp far less dangerous than it appears.
12. Blue-Winged Wasp
The blue-winged wasp (Scolia dubia) is a striking solitary species with a velvety black-and-reddish body and wings that shimmer with a metallic blue-black sheen in direct sunlight. It is typically seen flying low over lawns and garden beds in late summer, searching the ground for the grubs of green June beetles and Japanese beetles.
Once a female locates a grub, she digs down, paralyzes it with a sting, and lays a single egg that will develop inside the beetle larva. This makes the blue-winged wasp a genuinely useful ally against lawn-damaging beetle grubs, a connection worth knowing for anyone researching beetles found across North America and the insects that keep their populations in check.
13. Four-Toothed Mason Wasp
The four-toothed mason wasp (Monobia quadridens) is one of the most recognizable solitary wasps in the eastern United States, with a glossy black body broken by a single bold white band near the middle of the abdomen. Unlike the social wasps covered earlier, this species lives entirely alone, provisioning nests built in existing cavities such as old beetle borings in wood or abandoned carpenter bee tunnels.
Females hunt caterpillars to stock each nest cell, sealing the chambers with mud once an egg is laid, a nesting strategy shared with several other wasps covered later in this guide. Despite its wasp-like appearance, this species is docile and rarely stings unless directly handled.
Anyone building a broader mental catalog of backyard species may find it useful to browse a general overview of different types of insects to see how solitary wasps like this one fit into the wider insect world.
14. Great Black Wasp
The great black wasp (Sphex pensylvanicus) is a large, entirely jet-black solitary wasp with smoky, iridescent wings, often seen nectaring on flat-topped flowers like milkweed and mountain mint in mid to late summer. Despite its imposing size, it poses little threat to people since it has no colony to defend and stings only when physically restrained.
Females dig burrows in the ground and provision them with paralyzed grasshoppers and katydids, dragging prey that can outweigh them several times over back to the nest entrance. This hunting behavior makes the species a quiet but effective check on grasshopper populations in meadows and gardens, overlapping with the diverse insect communities found throughout Texas and much of the central United States.
15. Great Golden Digger Wasp
The great golden digger wasp (Sphex ichneumoneus) earns its name from the golden-orange hairs covering its head and thorax, contrasting with a reddish and black abdomen. Like its close relative the great black wasp, it is a solitary hunter that digs burrows in bare or sandy soil, often in sunny, well-drained patches of lawn or garden edge.
Females provision each nest cell with a single paralyzed katydid or cricket, sealing the chamber before moving on to dig another. Adults are frequently spotted feeding peacefully on goldenrod and other late-season flowers, making them a familiar sight across the same open habitats documented in regional surveys of insects found in Ohio.
16. Ground Digger Wasp
Ground digger wasps form a loose grouping of sand-nesting species, including various Bembix sand wasps, that share a preference for loose, sun-baked soil in open fields, dunes, and bare patches near trails. These solitary wasps are typically smaller and faster-flying than the great black and great golden digger wasps, with quick, darting movements as they excavate shallow burrows.
Many ground digger species provision their nests with flies rather than larger prey like katydids, and some return to the burrow repeatedly to supply food in stages rather than sealing the chamber after a single trip. Aggregations of these burrows sometimes appear in sandy residential lots or along unpaved paths, though the wasps themselves rarely bother people nearby.
17. Mud Dauber Wasp
Mud dauber is a catch-all name for several solitary wasp species that build distinctive tube- or cell-shaped nests out of mud rather than digging burrows or chewing paper pulp. Mud dauber wasps are typically black in color, often with pale yellow markings on the legs or thorax depending on the species.
The black-and-yellow mud dauber (Sceliphron caementarium) is the most frequently seen species, plastering rows of mud cells onto porch ceilings, bridges, and shed walls each spring. Females provision these cells with paralyzed spiders, a hunting habit that makes them genuinely beneficial around homes despite the sometimes unsightly mud nests they leave behind.
Readers interested in how these wasps fit into broader food webs can also look at a related guide on insects found in Canada, where mud daubers extend into the country’s warmer southern regions.
18. Nearctic Blue Mud-Dauber Wasp
The Nearctic blue mud-dauber (Chalybion californicum) stands out from its relatives with a sleek, metallic blue-black body that catches light differently than the duller black-and-yellow mud daubers nearby. Interestingly, this species often skips building its own nest entirely, instead taking over abandoned cells left by black-and-yellow mud daubers and refurbishing them with fresh mud.
Like other mud daubers, females hunt spiders almost exclusively, and this species is notable for sometimes capturing black widow spiders, which it paralyzes and seals inside nest cells as food for its larvae. This makes the blue mud-dauber one of the more quietly useful solitary wasps around homes and outbuildings where black widows might otherwise establish themselves.
19. Spider Wasp
Spider wasps belong to the family Pompilidae and include some of the most specialized hunters in the wasp world, built with long legs adapted for grappling with prey far larger than themselves. The most famous members are tarantula hawks (Pepsis species), found largely in the warm, arid Southwest, where they deliver one of the most painful stings of any North American insect to subdue tarantulas for their larvae.
Despite the intensity of their sting, tarantula hawks are remarkably docile toward people and rarely sting unless grabbed or stepped on, since they have no nest or colony to defend. These wasps are commonly observed nectaring on milkweed and other desert blooms throughout habitats covered in surveys of desert wildlife across North America, where tarantulas and their wasp predators share the same sandy terrain.
20. Potter Wasp
Potter wasps, part of the subfamily Eumeninae, are named for the small, jug-shaped mud nests some species construct on twigs and plant stems, complete with a narrow spout-like opening. The common potter wasp (Eumenes fraternus) is a frequent sight in gardens, recognizable by its slender black-and-white body and distinctly narrow, thread-like waist.
Females provision each tiny pot with several paralyzed caterpillars before sealing it shut and laying an egg, giving the developing larva a ready food supply. Because they hunt caterpillars that damage garden plants, potter wasps are considered beneficial insects alongside many of the pollinating species covered in a broader look at bees found in North Carolina, where both groups share similar flower-visiting habits as adults.
21. Gall Wasp
Gall wasps, family Cynipidae, are tiny insects, often just a few millimeters long, that cause some of the most visually bizarre growths found on oak and rose plants. Rather than stinging or hunting, females of genus Cynips and its relatives lay eggs inside plant tissue, and chemical signals from the developing larva trigger the plant to form a distinctive gall around it.
These galls come in an enormous range of shapes, from smooth marble-like balls to spiky, oak apple, or even fuzzy wool-like formations, depending on the wasp species and host plant. Gall wasps have no functional sting and pose zero threat to people, making them one of the gentlest entries on this entire list despite their alien-looking handiwork.
22. Cuckoo Wasp
Cuckoo wasps, family Chrysididae, are some of the most visually striking insects in North America thanks to a brilliant metallic green, blue, or red exoskeleton that shimmers like polished jewelry in sunlight. True to their name, species in genus Chrysis are brood parasites, sneaking eggs into the nests of other solitary wasps and bees rather than building nests of their own.
Their larvae hatch early and consume either the host’s egg or the food stores left behind, a survival strategy that requires no digging, hunting, or nest-building on the adult wasp’s part. Cuckoo wasps have a tough, sculpted exoskeleton that lets them curl into a defensive ball if a host wasp discovers the intrusion, protecting them from retaliation.
23. Pollen Wasp
Pollen wasps, subfamily Masarinae, break almost every rule associated with typical wasp behavior by feeding their larvae pollen and nectar instead of paralyzed prey. The western pollen wasp (Pseudomasaris vespoides) is the most recognizable North American species, often mistaken for a yellowjacket because of its black-and-yellow banding, though its behavior is entirely different.
Females provision mud-cell nests with a mixture of pollen and nectar collected specifically from penstemon and other tubular flowers, making this wasp an overlooked pollinator in western wildflower habitats. Their role parallels that of many better-known pollinators covered in guides to butterflies found across North America, since both groups depend on flowering plants and, in turn, help those plants reproduce.
24. Giant Wood Wasp
The giant wood wasp, or horntail, is represented in North America by the native white-horned horntail (Urocerus albicornis), a large, cylindrical insect that can look alarming thanks to a long, spear-like projection at the rear of its body. That projection is not a stinger at all but an ovipositor used to drill eggs deep into dead or dying conifer wood, meaning this species cannot sting people even if handled.
Larvae spend one to two years tunneling through timber before emerging as adults, a lifecycle that links them closely to the broader community of insects that eat wood across North American forests. Woodpeckers are among their most effective natural predators, drilling into infested logs to extract the larvae, a connection worth exploring further in a guide to woodpeckers found across North America.
Important Note: A few species on this list, including the European paper wasp and German yellowjacket, are non-native to North America. They are now well established across much of the continent and are typically identified alongside native species in regional pest and wildlife guides.
From ground-nesting yellowjackets to gentle, pollen-eating specialists, the types of wasps in North America cover an enormous range of behavior, size, and ecological roles. Most of the fear surrounding wasps traces back to a handful of defensive social species, while the majority of the continent’s wasp diversity is made up of solitary hunters, parasites, and pollinators that quietly go about their business without ever bothering people. Learning to tell them apart turns a reflexive swat into a moment of genuine curiosity about one of the most varied insect groups found anywhere outdoors.
