Most Common Types of Wasps (And How to Identify Them)

Wasp Head

As the temperature increases, you may notice an increase in flying insects, especially different types of wasps. While some of them are harmless, others can bite or sting. One (some may say aggressive) insect notorious for stinging is the wasp.

While these flying insects incite fear and even panic, many are harmless; people still see all types of wasps as pests, regardless of how dangerous they may be to humans.

As an experienced gardener and a firm advocate of sustainable and organic gardening practices, I firmly believe that understanding and coexisting with these often misunderstood insects is essential for maintaining a thriving garden ecosystem.

By recognizing different wasp species and their roles in pest control, we can promote a harmonious balance without resorting to harmful chemicals.

In this article, I’ll share how to identify various types of wasps that you may encounter in your garden. Armed with this knowledge, you will not only become more adept at recognizing these incredible creatures but also gain insights into their ecological significance.

Remember, our goal is not to eradicate wasps entirely but to appreciate their contributions as natural pest controllers while ensuring a safe and nurturing environment for both plants and humans.

What’s a Wasp?

The term wasp is for any insect member of the order Hymenoptera, suborder Apocrita, most of which are stinging. Wasps can be distinguished from the bees and ants of Apocrita by several physical and behavioral characteristics, particularly cause they have smooth and slender bodies and legs with relatively few hairs.

Also, wasps can be predatory or parasitic and possess stingers with few barbs that can be easily removed from their victims. Similar to Aprocrita relatives, wasps have a narrow petiole (waits) that attaches the thorax and the abdomen.

These flying insects have an antenna with twelve to thirteen segments and biting mouthparts, and they’re usually winged. Only females have a formidable sting in stinging species, which involves using a modified ovipositor (egg-laying structure) for venom-producing and piercing glands.

Mature wasps mainly feed on nectar and sometimes on larvae secretions. Larvae of predatory wasp species feed typically on insects, while parasitic species’ larvae feed on their hosts. Wasps have two subdivisions: solitary wasps and social wasps.

But what’s the difference between them? The main difference is that solitary wasps live alone, and social wasps live in colonies.

Social Wasps vs. Solitary Wasps

Although social wasps live in colonies, it doesn’t mean they have large colonies. A typical wasp nest can have somewhere around 10-12 members.

Bigger wasp nests can contain up to 10,000 members, and although it may sound like a considerable number, it is way below the 50,000 workers a bee colony can have.

Social wasps are part of the Vespidae family, which features yellow jackets and hornets, one of the most aggressive types of wasps.

The majority of wasp types belong to the solitary class, and they are primarily predators. Solitary wasps are often parasitic and do not build colonies, unlike social wasps. There are four groups which are the prominent solitary wasps:

  • Velvet wasps belong to the Mutillidae family
  • Scoolid wasps of the Scoliidae family
  • Tiphiid Wasps of the Tiphiidae family
  • Cuckoo wasps of the Chrysididae family

How to Identify a Wasp

With so many different species buzzing around, it is almost impossible to tell wasps apart by size. Some of them are less than half an inch, while others can grow up to 1.6 inches (Asian giant hornets), with the queen even being more oversized.

However, some physical characteristics and behavior patterns will allow you to tell wasps from bees.

Hair

Generally speaking, wasps are less hairy than bees because they are not primarily pollinators like bees. When bees fly from one flower to another, they use their body hair to collect pollen which is later stored on little brackets attached to their legs. For the most part, wasps do not care about pollen; hence they don’t need these little hairs.

Waist

Unlike bees, most wasps have a slim waistline. This is because the wasp’s abdomen narrows down where it meets the thorax at the upper part. However, there is one exception to the rule. Hornets do not have thin waists, so they can be mistaken for bees.

Nests

Wasps construct paper-like nests, usually made of chewed wood fibers mixed with saliva. These nests can be found in various locations, such as under eaves, in tree branches, or in ground cavities.

However, please exercise caution and maintain a safe distance when observing nests, as wasps can become defensive if they feel threatened.

Diet

Wasps are carnivorous and feed on other insects, spiders, and sometimes nectar. Unlike bees, wasps do not play a significant role in pollination, but they can be beneficial by controlling pest populations in your garden.

Behavior

Wasps are known for their active flight patterns and quick movements. They have a distinctive way of flying, darting back and forth in a more direct manner compared to bees. They may also exhibit territorial behavior around their nests.

Most Common Types of Wasps

Let’s take a look at the main wasp types you may want to know about. If you’re having a wasp problem in your home’s garden, there’s a high chance they will fall into one of the following breeds.

1. Yellow Jackets

Yellow Jackets are social wasps that can be commonly found in gardens and other outdoor areas. They are known for their aggressive nature, especially when their nests are disturbed. They’re attracted to sweet foods and can become a nuisance around picnics or outdoor gatherings.

This type of wasp is among the most aggressive and common wasp specie in the US. Of the 16 kinds of yellowjackets that live in the US, most have black and gold patterns, though there are a few with white instead of yellow, and some may have red markings on their bodies.

Most yellow jacket wasps are the same size as regular bees but are not as hairy. Their length varies between ⅜ inches and ⅝ inches.

To identify Yellow Jackets, look for their characteristic yellow and black striped abdomen. They are about half an inch to three-quarters of an inch long. Yellow Jackets build nests in the ground, in hollow trees, or occasionally in man-made structures like wall voids or attics.

If you spot Yellow Jackets in your garden, it’s important to exercise caution and avoid provoking them.

2. Cow Killer Wasp

This solitary parasitic wasp, also known as the Eastern Velvet ant, lays its eggs in bumble bee colonies. The females are wingless and covered in dense, velvety hair, while the males are winged and resemble typical wasps. Cow Killer Wasps are known for their potent sting, which is why they have gained the name “cow killer.”

To identify Cow Killer Wasps, look for the wingless females covered in dense, velvety hair. They are usually brightly colored, with patterns of red, orange, or yellow contrasting with black. The males resemble typical wasps with wings.

Cow Killer Wasps are not typically found in gardens unless there is a specific habitat suitable for their presence. Their sting can be quite painful, so it’s best to avoid handling or provoking them if encountered.

3. Thread Waisted Wasp

Northern Paper Wasps are another type of social wasp that can be found in gardens and are common in Midwestern states.

These wasps take their name from the material their nests are created of, usually regurgitated wood pulp mixed with saliva. You can find these nests hanging from trees.

Northern Paper wasps are brownish with yellow-reddish markings. They have distinctive long legs, so you can easily tell them apart from yellow jackets or bees.

These wasps are beneficial in the garden as they feed on insects, including caterpillars, flies, and beetle larvae.

Since Northern Paper Wasps provide natural pest control by preying on other insects, it’s generally best to coexist with them in the garden. If their nest is located in an inconvenient area, consider using physical barriers to discourage them from nesting in unwanted locations.

10. Potter Wasps

Potter Wasps are solitary wasps known for their unique nest-building behavior. They construct nests out of mud or clay, giving them the appearance of small pottery jars.

These solitary wasps’ main hobby is killing caterpillars, so when you think about it, their presence might be beneficial for your garden. Potter wasps are primarily black and have a yellow band over their thorax and another on their abdomen.

Once these wasps find a new home, they hunt down a caterpillar, paralyze it, and take it to their nest for the larvae to feed off.

To identify potter wasps, look for their characteristic nest structures made of mud or clay. The nests resemble small pots or jars, often attached to walls, rocks, or other surfaces. The wasps themselves can vary in color and size depending on the species.

Potter wasps are generally not aggressive and do not pose a threat to humans or plants. Their presence in the garden can be beneficial as they contribute to pollination and prey on small insects.

11. Spider Wasp

Mud Daubers are solitary wasps that are known for their unique nest-building behavior. They construct nests out of mud, which gives them their name. They have slender bodies, usually with yellowish wings and yellow marks.

Mud Dauber wasps usually dig 1-inch tunnels side by side and deposit one egg in each. These wasps’ nests can be found under porch ceilings and eaves and in barns, sheds, or garages.

To identify Mud Daubers, look for their slim body shape and long, thread-like antennae. They build nests that resemble elongated tubes made of mud, often attached to walls, under eaves, or in protected areas.

Mud Daubers are generally considered beneficial as they feed on spiders and other insects. If you spot their nests in your garden, it’s best to leave them undisturbed unless they are in an undesirable location.

In that case, carefully remove the nest and relocate it to a more suitable area.

16. European Paper Wasp

Cicada Killer Wasps are large solitary wasps that can be found in gardens where cicadas are present. They are one of the largest wasp species, with a robust body and powerful sting.

As the name suggests, they prey on cicadas and are not a threat to humans. These wasps have black bodies with yellow markings and can be seen working together to build a nest, which can be mistaken for a small animal’s burrow. Female cicada killer wasps dig burrows in the ground, while males are more commonly seen flying around.

These wasps hunt and attack cicadas in midair, paralyzing them with their strong sting, and take their bodies to their nests for their larvae to feed on. Mature Cicada Killer are attracted to flower nectar, so you can find them in gardens.

Cicada Killer Wasps are generally not aggressive toward humans but may cause concern due to their size and sting.

If their presence becomes a problem, consider seeking professional assistance for safe and effective management.
