Wasps and hornets are fascinating insects known for their diversity, unique behaviors, and important roles in ecosystems. While some species are social and build large colonies, others are solitary and focus on hunting or parasitizing other insects. These insects help control pest populations and contribute to pollination, making them valuable to nature. Although often feared for their stings, most species are not aggressive unless threatened. In this guide, you will explore 20 common types of wasps and hornets, along with their key characteristics, habitats, behavior, and lifecycle.
1. Yellowjacket
Yellowjackets are aggressive, social wasps known for their distinctive black and yellow markings. They are commonly found in many regions and are often seen around human activity, especially where food is present. Unlike some other wasps, yellowjackets can sting multiple times, making them one of the more feared stinging insects. They play a role in controlling pest populations but can become a nuisance during warmer months.
Identification
- Bright yellow and black striped body
- Smooth, shiny appearance
- Slender waist between thorax and abdomen
- Folded wings when at rest
- About 10–16 mm in length
- Fast, erratic flight pattern
Habitat and Distribution
Yellowjackets are widely distributed across North America, Europe, and parts of Asia. They build nests in a variety of locations, including underground burrows, wall cavities, tree hollows, and dense vegetation. Their nests are made from chewed wood fibers, creating a paper-like structure. They prefer areas close to food sources, which often brings them near human settlements, parks, and outdoor eating areas.
Behavior and Diet
Yellowjackets are highly social and live in colonies with a queen, workers, and males. They are active during the day and become especially aggressive when their nest is disturbed. Their diet includes insects, sugary foods, fruits, and human food scraps. They are both predators and scavengers, helping control pest insects but also becoming pests themselves in populated areas.
Lifecycle
The yellowjacket lifecycle begins with a fertilized queen emerging in spring to start a new colony. She lays eggs that develop into worker wasps, which take over nest building and food collection. The colony grows throughout summer, producing new queens and males toward the end of the season. Most of the colony dies in winter, leaving only fertilized queens to survive and start new colonies the following year.
2. Bald-faced Hornet
Bald-faced hornets are large, black-and-white wasps known for their aggressive defense behavior and distinctive aerial nests. Despite their name, they are actually a type of yellowjacket. These insects are highly social and live in colonies, often building large, enclosed nests in trees or shrubs. They play a beneficial role by preying on other insects but can be dangerous when disturbed.
Identification
- Black body with white or pale markings
- Distinct white face
- Thick, robust body
- Smooth, shiny surface
- About 12–18 mm in length
- Long wings folded along the body
Habitat and Distribution
Bald-faced hornets are found mainly in North America. They prefer wooded areas, gardens, and suburban regions where trees and shrubs are available for nesting. Their nests are usually built above ground, attached to branches or structures, and have a paper-like texture made from chewed wood fibers. These nests can grow quite large and house hundreds of individuals.
Behavior and Diet
These hornets are highly social and live in organized colonies with a queen and worker wasps. They are known for their aggressive defense of their nests and will attack if threatened. Their diet mainly consists of insects such as flies and caterpillars, as well as sugary substances like nectar and fruit. They are active during the day and contribute to natural pest control.
Lifecycle
The lifecycle begins in spring when a fertilized queen starts a new nest. She lays eggs that develop into workers, which then take over nest building and food gathering. The colony expands through summer, and by late season, new queens and males are produced. As winter approaches, the colony dies off, and only fertilized queens survive to restart the cycle.
3. European Hornet
European hornets are large, social wasps known for their impressive size and relatively less aggressive nature compared to other hornet species. They are one of the few true hornets found in many regions and are active both during the day and at night. Despite their intimidating appearance, they are generally not aggressive unless their nest is disturbed.
Identification
- Large, robust body
- Brown and yellow striped abdomen
- Reddish-brown head and thorax
- Prominent, curved antennae
- Strong wings with a slight amber tint
- Typically 18–25 mm in length
Habitat and Distribution
European hornets are native to Europe but are also found in North America and parts of Asia. They prefer forested areas, orchards, and suburban regions. Their nests are usually built in hollow trees, wall voids, attics, or other sheltered spaces. These nests are made from chewed wood fibers, forming a paper-like structure. They tend to choose dark, enclosed areas for nesting.
Behavior and Diet
European hornets are social insects that live in colonies with a queen and worker wasps. They are unique among hornets for being active at night and are often attracted to lights. Their diet includes insects such as flies and beetles, as well as tree sap and fruits. They help control pest populations but can become defensive if their nest is threatened.
Lifecycle
The lifecycle begins when a fertilized queen emerges in spring and starts building a nest. She lays eggs that develop into worker hornets, which take over colony duties. The colony grows through summer, producing new queens and males later in the season. As winter approaches, most of the colony dies, leaving only fertilized queens to survive and begin new colonies the following year.
4. Asian Giant Hornet
Asian giant hornets are the largest hornet species in the world, known for their powerful sting and strong mandibles. They are often feared due to their size and defensive behavior, especially when their nests are threatened. Despite their reputation, they play an important role in controlling insect populations. These hornets are highly organized and live in structured colonies.
Identification
- Very large body size
- Orange or yellow head
- Dark brown or black thorax
- Bold yellow and black striped abdomen
- Large mandibles for cutting prey
- Typically 35–50 mm in length
Habitat and Distribution
Asian giant hornets are native to East Asia, including countries like Japan, China, and Korea. They prefer forested and mountainous regions, where they build nests underground, often in abandoned burrows or tree roots. These environments provide protection and stable conditions for colony development. In some areas, they have been reported outside their native range.
Behavior and Diet
These hornets are social and live in colonies with a queen and workers. They are known for their hunting behavior, especially targeting other insects like bees. Their diet includes large insects, tree sap, and sugary substances. They can be highly aggressive when defending their nest and may attack in groups. Their strong jaws allow them to capture and process prey efficiently.
Lifecycle
The lifecycle begins in spring when a fertilized queen emerges and establishes a new nest. She lays eggs that develop into worker hornets, which take over tasks such as foraging and nest expansion. The colony grows through summer and produces new queens and males in late season. As winter approaches, the colony dies off, leaving only fertilized queens to survive and restart the cycle.
5. Paper Wasp
Paper wasps are slender, social wasps known for building umbrella-shaped nests from paper-like material. They are generally less aggressive than yellowjackets but will defend their nests if threatened. These wasps are commonly seen around homes, gardens, and open structures. Paper wasps are beneficial insects, as they help control pest populations by feeding on other insects.
Identification
- Slender body with a narrow waist
- Brown, reddish, or yellow coloration
- Long legs that hang down during flight
- Smooth, shiny body surface
- Wings folded lengthwise when at rest
- Typically 15–20 mm in length
Habitat and Distribution
Paper wasps are found worldwide, especially in warm and temperate regions. They build their nests under eaves, roofs, branches, and other sheltered areas. Their nests are made from chewed wood fibers mixed with saliva, forming a papery structure with open cells. These wasps prefer locations that provide protection from rain and predators while being close to food sources.
Behavior and Diet
Paper wasps are social and live in small colonies led by a queen. They are active during the day and spend time building nests, foraging, and caring for larvae. Their diet includes nectar and small insects such as caterpillars, which they feed to their young. They are generally non-aggressive unless disturbed, making them less of a threat compared to other wasps.
Lifecycle
The lifecycle begins in spring when a fertilized queen starts a new nest and lays eggs. The eggs develop into worker wasps that take over nest building and food collection. The colony grows throughout summer, and new queens and males are produced later in the season. As temperatures drop, the colony dies, leaving only fertilized queens to survive the winter and begin new colonies.
6. Red Wasp
Red wasps are a type of paper wasp known for their reddish-brown coloration and relatively calm behavior compared to more aggressive wasps. They are commonly seen in warm regions and often build nests around human structures. Although they can sting, they usually do so only when threatened. Red wasps are beneficial because they help control pest insects in gardens and natural areas.
Identification
- Reddish-brown or rust-colored body
- Slender shape with a narrow waist
- Long legs that dangle during flight

These wasps choose locations that provide protection from weather and easy access to food.
Behavior and Diet
Red wasps are social insects that live in small colonies. They are active during the day and spend their time building nests, hunting, and feeding larvae. Their diet includes nectar, sugary substances, and insects like caterpillars. They play an important role in controlling garden pests. While generally calm, they will defend their nest if disturbed.
Lifecycle
The lifecycle starts when a fertilized queen builds a nest in spring and lays eggs. These eggs develop into worker wasps that take over colony duties. The colony grows through the summer, producing new queens and males later in the season. As colder weather arrives, most of the colony dies, leaving only fertilized queens to survive and restart the cycle.
7. Mud Dauber
Mud daubers are solitary wasps known for building tube-shaped nests made of mud. Unlike many social wasps, they are not aggressive and rarely sting unless directly handled. These wasps are beneficial because they help control spider populations. Mud daubers are often seen flying around walls, ceilings, or sheltered outdoor spaces where they construct their nests.
Identification
- Slender, elongated body
- Black or metallic blue coloration (sometimes with yellow markings)
- Very narrow, thread-like waist
- Long legs
- Smooth, shiny appearance
- Typically 15–25 mm in length
Habitat and Distribution
Mud daubers are found worldwide, especially in warm and temperate regions. They prefer sheltered areas such as under roofs, bridges, walls, and inside sheds. Their nests are made from mud and are often attached to solid surfaces. Each nest consists of several tube-like chambers where they store prey and lay eggs. These habitats provide safety from weather and predators.
Behavior and Diet
Mud daubers are solitary and do not live in colonies. They hunt spiders, which they paralyze and place inside their mud nests as food for their larvae. Adult mud daubers feed mainly on nectar. They are generally non-aggressive and focus on nest building and hunting rather than defending territory.
Lifecycle
The lifecycle begins when a female builds a mud nest and places paralyzed spiders inside. She then lays an egg in each chamber. The larva hatches and feeds on the stored spiders before pupating. After development, the adult emerges from the nest. This cycle repeats as new generations are produced.
8. Potter Wasp
Potter wasps are solitary wasps known for their unique nest-building behavior, creating small, pot-shaped structures from mud. These nests are often attached to walls, rocks, or plant stems. Potter wasps are generally non-aggressive and rarely sting humans. They play an important ecological role by controlling insect populations, especially caterpillars.

Their nests are commonly seen attached to solid surfaces like walls, rocks, or branches. These habitats provide easy access to materials like mud and a steady supply of prey.
Behavior and Diet
Potter wasps are solitary and do not form colonies. Each female builds her own nest and provisions it with food for her offspring. They hunt caterpillars and other soft-bodied insects, which they paralyze and store inside the nest. Adult potter wasps feed mainly on nectar. They are calm and rarely show aggressive behavior unless handled.
Lifecycle
The lifecycle begins when a female constructs a mud nest and places paralyzed prey inside. She lays an egg in the chamber, and the larva feeds on the stored food after hatching. It then pupates within the nest before emerging as an adult. This independent lifecycle repeats with each new generation.
9. Cicada Killer Wasp
Cicada killer wasps are large, solitary wasps known for hunting cicadas to feed their young. Despite their intimidating size, they are generally non-aggressive toward humans. These wasps are often seen flying low over lawns or digging burrows in sandy soil. They play a beneficial role by controlling cicada populations.

These wasps do not build their own nests but instead lay their eggs in the nests of other insects, such as bees or other wasps. They prefer environments where host nests are abundant.
Behavior and Diet
Velvet ants are solitary and spend much of their time searching for host nests. Females enter the nests of other insects to lay their eggs. The larvae then feed on the host’s larvae or stored food. Adult velvet ants feed mainly on nectar. They move quickly and are often seen running across the ground.
Lifecycle
The lifecycle begins when a female lays an egg inside the nest of another insect. The larva hatches and feeds on the host or its provisions. It then pupates within the host nest and eventually emerges as an adult. This parasitic lifecycle allows velvet ants to reproduce without building their own nests.
12. Mason Wasp
Mason wasps are solitary insects known for building nests using mud or other natural materials. They are calm and rarely sting, making them less of a concern around humans. These wasps are beneficial because they help control pest insects. Their nesting behavior is similar to potter wasps, but they often use existing cavities instead of building exposed mud pots.

Instead of building fully exposed nests, they often use these spaces and seal them with mud. These habitats provide protection and easy access to prey.
Behavior and Diet
Mason wasps are solitary and do not form colonies. Each female prepares her own nesting site and gathers food for her larvae. They mainly hunt caterpillars and other soft-bodied insects, which they paralyze and store in their nests. Adult wasps feed on nectar and are often seen visiting flowers. They are generally calm and non-aggressive.
Lifecycle
The lifecycle begins when a female places paralyzed prey inside a cavity and lays an egg. The larva hatches and feeds on the stored food. After completing its development, it pupates inside the sealed chamber and later emerges as an adult wasp, continuing the cycle independently.
13. Ichneumon Wasp
Ichneumon wasps are a large group of parasitic wasps known for their slender bodies and long egg-laying structures. They are generally harmless to humans and play a vital role in controlling pest insect populations.

FAQs
What is the difference between wasps and hornets?
Hornets are actually a type of wasp, usually larger and more robust. Wasps include many species with varying sizes and behaviors, while hornets are a specific subgroup known for their social colonies and larger nests.
Are all wasps aggressive?
No, not all wasps are aggressive. Social wasps like yellowjackets can be defensive, especially near their nests. However, many solitary wasps, such as mud daubers and potter wasps, are generally calm and rarely sting humans.
Do wasps have any benefits to humans?
Yes, wasps are beneficial for ecosystems and agriculture. They help control pest insects by hunting them or parasitizing them. Many wasps also contribute to pollination by visiting flowers for nectar.
Can wasps sting more than once?
Most wasps can sting multiple times because their stingers are not barbed like those of bees. This makes them capable of defending themselves repeatedly if they feel threatened.
Where do wasps usually build their nests?
Wasps build nests in a variety of places depending on the species. Some build paper nests in trees or buildings, while others dig burrows in the ground or use existing cavities like hollow stems or cracks.
