This type of wasp is known for its careful precision when hunting its prey and is an important part of the natural ecosystem. 

This species of wasp is considered beneficial because they control certain weevil populations. They can be seen buzzing around gardens, fields, or anywhere else that is home to their preferred prey.

While Weevil Wasps are generally not aggressive toward humans, it is best to stay away as any wasp may sting if disturbed or threatened.

2. Spider Wasp

Spider Wasps, also known as Entypus, are impressive types of wasps in Maryland. These solitary predators hunt and sting spiders as prey, then paralyze them before dragging them back to their nests to feed their larvae.

They have a black body with an orange-red patch on their thorax and dark brown wings. They are easily recognizable by their long antennae and distinctive flight pattern.

Spider Wasps are extremely beneficial insects, helping to control the spider population in Maryland. They can often be seen darting around in gardens, woodlands, and meadows.

If you spot one of these fascinating creatures, remember not to disturb them, as they play an important role in our ecosystem.

3. Thread-Waisted Wasp

Thread-waisted wasps, also known as Sphex lucae, are a species of wasp found in Maryland. These insects are typically identified by their long, thin waist and black and yellow stripes on their bodies.

Thread-waisted wasps, which are one of the types of wasps in Maryland, feed on other insects and larvae, as well as nectar. They construct burrows and nests in the soil and often hunt for food in the evening.

The female thread-waisted wasp is responsible for laying her eggs in the soil. She also feeds her young until they hatch and develop into adult wasps. The adults can then search for food and build their own nests.

Thread-waisted wasps are beneficial to their environment as they are predators that help control pest populations.

4. Squarehead Wasp

The Squarehead Wasp, or Ectemnius spp., is a type of wasp commonly found in Maryland. This species can be easily identified by its distinctive, square-shaped head and reddish-brown and yellow-striped abdomen.

These wasps are solitary insects, meaning they live and hunt alone. They are not left out from our list of types of wasps in Maryland, and they primarily feed on aphids, small insects, and spiders.

Squarehead Wasps build their nests in the ground, which are composed of a few cells connected to each other with mud and plant material. The nests are generally found in dry, open places such as meadows, gardens, and lawns.

Despite their ability to sting humans if threatened, Squarehead Wasps are important pollinators and help to control pest populations.

They are often found on sandy beaches but also inhabit other areas such as grasslands, fields, and even gardens. The most common of these species is Bembix Americana.

Sand Wasps feed mainly on other insects, building their nest by digging small holes in sandy soil. They lay eggs in these nests, which will later hatch into larvae. Once the larvae mature, they become adult wasps that will go on to make their own nests.

7. Potter Wasp

The Potter Wasp, or Ancistrocerus antilope, is a type of wasp native to Maryland. These wasps are typically found in woodland areas and on the edges of fields and meadows.

Their black bodies identify them with yellow markings and their ability to form clay-like nests that they use to raise their young. 

Potter Wasps feed on flower nectar and caterpillars, which they gather and return to their nest. They can be seen hovering around flowers, looking for food.

Potter Wasps, one of the various types of wasps in Maryland, also help control insect populations. 

The females lay eggs inside a caterpillar host, where the larva develops and feeds on the host until it pupates into an adult wasp. This helps keep the caterpillar population under control in the area.

As a beneficial species, the Potter Wasp is important in the garden or your home.

8. Norton’s Giant Ichneumon Wasp

Norton’s Giant Ichneumon Wasp (Megarhyssa nortoni) is one of the most commonly found types of wasps in Maryland. This large wasp species can be recognized by its long antennae and bright orange and black striped body.

Cuckoo Wasps, also known as Cicada Killers, are among the many types of wasps in Maryland. They are typically about 2 inches long and have yellow-orange stripes on their abdomens. They hunt for prey, such as cicadas, during the summer months and feed on the nectar of flowers. 

While they do not normally attack humans, they may sting if provoked. It is important to take caution when near them and to leave them alone if possible. These solitary wasps build small nests near the ground or in crevices. 

If a nest is found, it is best to leave it alone, as Cuckoo Wasps are beneficial in controlling cicada populations.

To reduce the risk of being stung, it is recommended to avoid areas where these wasps may live and to wear protective clothing if necessary.

16. Common Thread-Waisted Wasp

The Common Thread-waisted Wasp (Ammophila procera) is one of the most common wasp species in Maryland. This species has a long slender waist, black and yellow striped body, and reddish-brown wings.

Boll’s Potter Wasp builds its nests in small groups or colonies and feeds on insects, such as caterpillars, beetle larvae, and spiders. They are relatively peaceful wasps and do not aggressively attack humans unless provoked.

However, they are types of wasps in Maryland that can still sting if they feel threatened. Although they are generally considered harmless, it is best to avoid disturbing their nest as they may become defensive if provoked.

18. Braconid Wasp

As we approach the end of this list of the many types of wasps in Maryland, the Braconid Wasp is not missing.

This small, dark-colored insect is a member of the family Braconidae and can be identified by its slender body and long antennae. Over 1,800 species of Braconid Wasps are found worldwide, many of which are found in Maryland.

Braconid Wasps are considered to be beneficial to gardeners as they prey on many species of insects that feed on garden plants, such as aphids and caterpillars.

The female Braconid Wasp will lay her eggs on her host’s body, typically a caterpillar or aphid. This is where her larvae will feed on the host until it is ready to pupate. 

These insects have very distinct features, including three-segmented antennae, two pairs of wings, and two compound eyes.

They range in size from 2 to 30 millimeters and are usually black or brown. Braconid Wasps are also quite hardy and can survive cold and dry temperatures.

This nest is typically suspended from an overhang such as a roof or tree branch. As they are social, the nest is usually inhabited by several generations of wasps. 

The colonies have a single queen, and all other nest inhabitants are female workers who feed the larvae. These wasps feed on nectar, fruit, and other insects.

They do not generally sting unless provoked, but if disturbed, they may sting in defense of the colony. So if you’re spending time outside, be mindful of their presence and always observe from a safe distance. 

Overall, the Common Paper Wasp is a fascinating creature to observe and appreciate from a distance.
