13 Types of Wasps in Mississippi (And How to Tell Them Apart)
September 16, 2026
Mississippi’s warm, humid climate supports a surprising range of wasps, and most Mississippians only recognize two or three of them on sight. Learning the different types of wasps in Mississippi helps homeowners, gardeners, and curious hikers tell a nuisance yellowjacket from a harmless, garden-friendly hunter. Some of these insects sting readily when disturbed, while others cannot sting people at all despite looking intimidating.
This guide walks through 13 wasps found across the state, from the paper wasps nesting under porch eaves to the giant ichneumon wasps that drill their eggs into hardwood logs. Each species has its own nesting habits, temperament, and role in controlling garden pests. For a broader look at stinging insects beyond the Magnolia State, the different types of wasps found across North America follow many of the same patterns.
Pro Tip: Most wasps in Mississippi are solitary and would rather fly away than sting. Reserve caution for social species like yellowjackets and hornets, which defend their colonies aggressively when a nest is disturbed.
1. Paper Wasp
The paper wasp is one of the most familiar sights in Mississippi backyards. Polistes exclamans, often called the common paper wasp, is one of the most commonly seen types of wasps in Mississippi. These social insects have slender bodies with reddish-brown and black stripes and a yellowish head, and they’re easy to spot hovering around porch corners and garden fences.
The paper wasp will build its nest out of chewed wood fibers that they mix with saliva to form a paper-like material. Colonies favor open, umbrella-shaped combs suspended from a single stalk, with hexagonal cells visible from below. Workers stay busy hunting caterpillars and visiting flowers throughout the day, and they also play an important role in controlling garden pests such as aphids, caterpillars, and beetles.
Paper wasp colonies are relatively modest in scale. Colonies stay relatively small, typically 20 to 75 workers, which makes paper wasps less explosive than yellowjackets when disturbed. Even so, females sting repeatedly and will defend the nest aggressively if you approach within a foot or two. Gardeners dealing with similar species elsewhere may find the wasps found in Ohio a useful point of comparison, since several Polistes species overlap in range.
2. Yellowjacket
Yellowjackets are the wasps most people picture when they hear the word “wasp.” The Eastern yellowjacket, Vespula maculifrons, has bold black-and-yellow banding and a stockier build than a paper wasp. Unlike the paper wasp’s open nest, yellowjackets often nest underground or inside wall voids, which makes their colonies easy to disturb accidentally while mowing or gardening.
Colony members stay busy foraging. Eastern Yellowjackets feed on flower nectar and fruit juices but spend much of their time gathering food, such as insects and occasionally carrion, for the colony’s larvae, with workers cutting up captured insects and feeding the paste to hungry larvae. This appetite for other insects makes yellowjackets useful predators in gardens, even though their reputation is mostly negative.
That reputation is not undeserved. Yellow jackets are known for their aggressive behavior and will sting multiple times if they feel threatened. Anyone who has stepped near a hidden ground nest while working in the yard knows how quickly a calm afternoon can turn into a scramble. Readers dealing with similar stinging insects up north may want to check the wasps common in Minnesota, where several Vespula species overlap with Mississippi’s populations.
3. Bald-faced Hornet
Despite the name, the bald-faced hornet isn’t a true hornet at all ā it’s a close relative of the yellowjacket. Dolichovespula maculata earns its name from the mostly white face set against a black-and-white patterned body. Bald-faced hornets are large, black and white wasps that are native to Mississippi.
These wasps build enclosed, papery nests high in trees or under roof eaves, and colonies can grow large by late summer. These aggressive insects will defend their nests vigorously if they feel threatened, so it’s important to avoid disturbing their colonies. Because a disturbed nest can send multiple workers after an intruder at once, professional removal is often the safer route when a colony builds too close to a doorway or walkway. The wasp species documented in Iowa include the same bald-faced hornet, since its range extends across most of the continental United States.
4. Mud Dauber
Mud daubers are some of the calmest wasps a Mississippian is likely to encounter. The black-and-yellow mud dauber, Sceliphron caementarium, and the metallic blue mud dauber both build their nests from wet soil rather than chewed wood pulp. Mud daubers are a type of wasp that constructs nests out of mud, usually black or metallic blue in color with a narrow waist, and they are not aggressive and rarely sting humans.
These solitary hunters provision their mud cells with paralyzed spiders rather than caterpillars, making them valuable for keeping spider populations in check around porches and sheds. However, they can be a nuisance if they build their nests in areas where people frequent, since the dried mud tubes can accumulate on siding, window frames, and patio furniture over a season. Readers curious whether other backyard insects pose similar low risk can browse the insects that are not poisonous for more harmless species worth recognizing.
5. Carolina Paper Wasp
Often called the red wasp locally, Polistes carolina is larger and darker than its exclamans cousin, with a reddish-brown body and dark wings. Polistes carolina, the red wasp, and Polistes exclamans are the two paper wasp species Mississippi homeowners see most often. The two are easy to tell apart once you know what to look for: the Carolina paper wasp is noticeably bigger and lacks the yellow-and-black striping of the common paper wasp.
Nest construction follows the same pattern as other Polistes species. Both species build the same style of nest: an open, umbrella-shaped comb with visible hexagonal cells, suspended from a single paper stalk. Mississippi State University Extension’s Bug’s Eye View notes that Polistes exclamans is among the most frequently encountered paper wasps in the state, with colonies commonly found nesting on homes, fences and similar structures, and the Carolina paper wasp tends to favor the same sheltered spots. For comparison across state lines, the wasps recorded in New Jersey include several Polistes species with similar nesting preferences.
6. Four-toothed Mason Wasp
The four-toothed mason wasp is frequently mistaken for something far more aggressive. Monobia quadridens has striking black-and-white coloring, and its contrasting black-and-white coloring can make this medium-sized wasp seem a little scary, and at first glance it is often confused with the more territorial bald-faced hornet. Look closer, though, and the behavior tells a very different story.
Four-toothed Mason Wasps are solitary, docile wasps in Mississippi, and they don’t even defend their nests. That said, handling one is not advisable: females can sting if you handle them, with a sting comparable to a bald-faced hornet, while males lack stingers but will jab with the pointy end of their abdomen, which feels more like a pin-prick.
Females build their broods in existing cavities rather than constructing anything from scratch. She begins filling her nest by crawling into the tunnel’s far end and laying an egg, then hunts caterpillars, paralyzing them with her sting and placing them in front of the egg for the larva to eat when it hatches. This makes the four-toothed mason wasp a quiet but effective caterpillar predator in gardens and orchards. Anyone comparing insect diversity across regions might enjoy the insects found throughout Ohio, where this same mason wasp also turns up.
7. Cicada Killer
Few insects trigger as much alarm on sight as the cicada killer, despite being mostly harmless to people. Sphecius speciosus is a genuinely large wasp, and according to Mississippi State University Extension, cicada killers, which are the largest wasps in the South, nest in burrows in the soil, which they provision with one to three paralyzed cicadas before depositing an egg.
The life cycle runs on a yearly clock tied to its prey. The hatching cicada killer larva feeds on these cicadas and develops to the pupal stage, remaining in the burrow to emerge as an adult the following year. Males patrol territory near burrows but pose no sting risk at all, since male cicada killers certainly look intimidating, but male cicada killers can’t sting because they do not have a stinger.
Females do carry a functional sting, reserved almost entirely for subduing cicadas. These solitary wasps are not aggressive and rarely sting humans ā you pretty much have to grab one in your hand to force a sting. Homeowners noticing clusters of burrows in sandy, sparse lawn patches are usually watching cicada killer activity rather than anything dangerous. Those exploring similar large ground-nesting species elsewhere can browse the insects native to Texas, where cicada killers are equally common.
8. Velvet Ant
Despite the name, the velvet ant is a wingless female wasp, not an ant at all. The Eastern velvet ant, Dasymutilla occidentalis, is covered in dense red-and-black fuzz and is the largest and most frequently spotted mutillid wasp in the state, according to Mississippi State University Extension. People who have been stung by an Eastern velvet ant say it has the most painful sting of any insect in the Southeast ā more painful than a red wasp.
That reputation has earned it a memorable nickname. Most southerners call these cow killer ants, and most folks who have experienced a sting feel this name is most appropriate. The good news is that encounters are rare, since velvet ants are not aggressive, and stings are rare ā they only sting when stepped on with bare feet, sat on, rolled on while playing in the grass, or improperly handled.
Velvet ants have a fascinating and slightly grim relationship with another wasp on this list. Female velvet ants are often seen scurrying over the ground in search of cicada killer wasp nests or nests of other large ground-nesting wasps, and if the cicada killer larva is parasitized by an Eastern velvet ant, an adult velvet ant emerges from the burrow the following year instead. Their black-and-red warning coloration overlaps visually with some ground-dwelling arachnids, so readers curious about lookalikes might check the spiders documented in Mississippi for comparison.
9. Giant Ichneumon Wasp
The black giant ichneumon wasp looks like something built to terrify, but it poses zero sting risk to people. Megarhyssa atrata is dark-bodied with an ovipositor that dwarfs its own body length. According to Mississippi State University Extension, this wasp has a 4-inch stinger and can drill through several inches of hardwood to get to its prey, but fortunately it does not sting people and is only interested in laying its eggs in the larvae of another woodboring insect.
Size-wise, it’s a genuine contender among the state’s largest wasps. Giant ichneumon wasps are some of the largest parasitic wasps in the state, second only to cicada killer wasps, and a large female can be over 2 inches long with an ovipositor that measures an additional 4 inches or more. Watching one drill patiently into a dead log is one of the more memorable sights in a Mississippi forest.
Key Insight: That long, thread-like structure trailing behind a giant ichneumon wasp is both an ovipositor and a stinger. It only threatens the wood-boring larvae hidden inside logs and stumps, never people.
10. Norton’s Giant Ichneumon Wasp
A close relative of the black giant ichneumon wasp, Norton’s giant ichneumon wasp (Megarhyssa nortoni) shares the same startling silhouette but wears a different color pattern. Mississippi State University Extension describes a related large Megarhyssa species as similar in size, but brown and yellow, colored much like a Guinea wasp ā a description that fits Norton’s giant ichneumon wasp closely, distinguishing it from its darker cousin at a glance.
The long trailing filament that makes these wasps so distinctive serves a dual purpose. Sometimes there is a debate over whether that long stylus of female ichneumon wasps is a stinger or an ovipositor ā it’s both, and these wasps do sting, though the sting is deadly only to wood wasp larvae.
The mechanics behind it are equally remarkable: the long ovipositor consists of three filaments, two of which form a protective cover for the horsehair-thin, hollow filament in the center, which drills into the wood with the aid of special wood-digesting enzymes and deposits the egg in the host gallery. Anyone fascinated by this level of insect specialization might also enjoy browsing the insects recorded across New York, where related ichneumon species turn up in similar wooded habitat.
11. Noble Scoliid Wasp
The noble scoliid wasp brings a completely different look to Mississippi’s wasp lineup. Scolia nobilitata measures about 1 inch in size and has a mostly black body with yellow markings on the legs, abdomen, and thorax, and the wings are clear, and the head has two small yellow stripes. The overall effect is a sleek, almost armored appearance quite different from the fuzzy velvet ant or the papery-nested Polistes species.
Habitat preference sets this species apart as well. These wasps are usually found near wooded areas such as forests, swamps, and meadows, and they typically feed on other insects, spiders, and nectar, and are solitary, meaning they do not form colonies like some other species of wasps. Their nesting strategy leans on whatever shelter the landscape offers: they create their nests in hollowed-out logs, tree trunks, or areas with loose soil, such as banks and embankments.
Because noble scoliid wasps target beetle grubs underground, they function as a quiet form of natural pest control in lawns and garden beds, similar in concept to the beneficial insects highlighted among the insects found in the Amazon rainforest, where parasitic wasp relationships are just as central to the ecosystem.
12. Northern Paper Wasp
The Northern paper wasp rounds out Mississippi’s trio of common Polistes species. Polistes fuscatus lives in Mississippi and other parts of the southern United States and belongs to the Polistes genus, placing it alongside the common paper wasp and Carolina paper wasp already covered above. This wasp has a brown body with yellow marks on it, and it favors the same open, umbrella-style nests built from chewed plant fiber.
One trait sets this species apart from its relatives: individual recognition. Researchers have found that Northern paper wasps can distinguish nestmates from unfamiliar wasps by facial markings, a rare ability among insects. Yellow jackets and paper wasps share a close family tie with the Northern Paper Wasp, all belonging to the same broader wasp family that builds nests from paper-like material rather than mud or soil. Readers wanting to see how paper wasp populations shift in cooler climates can compare notes with the wasps documented in Oregon.
13. Red-and-Black Mason Wasp
The red-and-black mason wasp is one of the smaller, less conspicuous species on this list, and it rarely draws attention unless someone is watching flowers closely. Pachodynerus erynnis shows a patchwork of reddish-orange and black across its body, a pattern that helps distinguish it from the yellow-and-black banding of paper wasps and yellowjackets. Like the four-toothed mason wasp, it belongs to the Eumeninae, a subfamily of solitary potter and mason wasps that build or seal nest cells with mud rather than chewed wood pulp.
Females provision their nest cells with paralyzed caterpillars for their larvae, sealing each cell with a mud plug once it’s stocked. Because they nest alone in existing cavities ā old nail holes, hollow stems, or abandoned insect burrows ā rather than defending a shared colony, red-and-black mason wasps have little reason to sting unless directly handled. Gardeners who want to support beneficial solitary wasps like this one can find general guidance in the broader roundup of different types of insects that quietly help manage pest populations outdoors.
Comparing Mississippi’s Wasps at a Glance
With 13 species covering such different sizes, nesting habits, and temperaments, a side-by-side comparison makes the differences easier to remember.
| Wasp | Social or Solitary | Typical Nest Location | Sting Risk to People |
|---|---|---|---|
| Paper Wasp | Social | Eaves, shrubs, fences | Moderate if nest disturbed |
| Yellowjacket | Social | Underground, wall voids | High, defends nest aggressively |
| Bald-faced Hornet | Social | Trees, roof eaves | High, defends nest aggressively |
| Mud Dauber | Solitary | Mud tubes on structures | Very low |
| Carolina Paper Wasp | Social | Eaves, fences, sheds | Moderate if nest disturbed |
| Four-toothed Mason Wasp | Solitary | Existing cavities | Low, only if handled |
| Cicada Killer | Solitary | Soil burrows | Very low |
| Velvet Ant | Solitary | Parasitizes ground nests | Low but very painful sting |
| Giant Ichneumon Wasp | Solitary | Drills into dead wood | None to humans |
| Norton’s Giant Ichneumon Wasp | Solitary | Drills into dead wood | None to humans |
| Noble Scoliid Wasp | Solitary | Hollow logs, loose soil | Low |
| Northern Paper Wasp | Social | Eaves, meadows, shrubs | Moderate if nest disturbed |
| Red-and-Black Mason Wasp | Solitary | Existing cavities, sealed with mud | Very low |
A pattern emerges quickly from this table: solitary species like mud daubers, cicada killers, and both giant ichneumon wasps present far less risk to people than the social species that defend a shared colony. This lines up with broader research on Mississippi’s beneficial insects, since a USDA pollinator habitat fact sheet notes that wasps are also considered beneficial for gardens and agricultural production because they feed on crop pests, and that most wasps are solitary and do not have colonies to defend, flying away rather than stinging unless stepped on or handled.
Important Note: Anyone who experiences swelling well beyond the sting site, difficulty breathing, dizziness, or hives after a wasp sting should seek medical attention promptly, since these can be signs of a more serious allergic reaction. This article is educational and does not replace guidance from a medical professional or licensed pest control provider.
Living Alongside Mississippi’s Wasps
Most of the wasps covered here spend far more time hunting caterpillars, spiders, and beetle grubs than they do bothering people. Recognizing the difference between a docile mason wasp and a defensive yellowjacket colony makes it much easier to decide when to simply observe and when to call in professional help. Anyone whose curiosity extends beyond wasps can explore the wider mix of insects that bite or compare notes with the diverse insects found across Canada to see how these families of pollinators and predators shift from one climate to the next.
For homeowners specifically weighing removal versus tolerance, the safest approach is usually identification first, action second. A paper wasp nest tucked under a rarely-used shed eave can often be left alone through the season, while a yellowjacket nest near a doorway or a bald-faced hornet colony overhanging a walkway calls for more caution. Understanding which of these 13 types of wasps in Mississippi is actually present on a property turns a stressful guessing game into a straightforward decision.
