Louisiana is home to a wide variety of insects, including several species of wasps.

Wasps can range from the small and non-aggressive paper wasp to the large and intimidating bald-faced hornet.

These creatures play an important role in our ecosystem, and it’s important to understand the different types of wasps in Louisiana. 

In this blog post, we’ll look at some of the most common types of wasps in Louisiana. We’ll also discuss the differences between these types and the best ways to identify them.

Shall we?

1. Braconid Wasp

The braconid wasp, also known as Atanycolus spp., is a small and slender insect found in Louisiana.

These wasps are typically black and yellow, although the exact patterns may vary from species to species.

Braconid wasps are primarily predators of small insects, such as caterpillars, leafhoppers, and aphids. 

As beneficial predators, these wasps help to control harmful insect populations that can damage plants or cause health issues in humans.

The females of this species lay their eggs on the larvae of other insects, so they can feed on them once they hatch.

In some cases, braconid wasps, the starter of the list of different types of wasps in Louisiana, may be seen in gardens or other areas where their prey is found. 

They can also be found in wooded areas, where they may take advantage of various insect populations.

Due to their important role as predators, these wasps play a vital role in keeping Louisiana’s environment healthy and balanced.

2. Common Paper Wasp

The Common Thread-waisted Wasp is a solitary species that do not form colonies like other wasps in Louisiana.

They are mainly active during the summer, where they can be found in meadows, grasslands, and wooded areas.

These wasps prefer to nest in underground burrows or small spaces, such as the cracks between bricks or logs. 

They feed on nectar and other insects, making them beneficial for pest control.

While their sting is painful, the Common Thread-waisted Wasp does not pose a major risk to humans unless disturbed or threatened.

For this reason, they can be a welcome guest in gardens or other areas where they can provide natural pest control.

4. Cuckoo Wasp

Cuckoo Wasps are types of wasps in Louisiana. They are usually quite small and have large eyes and long, slender bodies.

Their colors range from yellow to black and can be found anywhere in Louisiana. They get their name due to their habit of laying eggs in the nests of other wasps.

They are predatory wasps, meaning they hunt and feed on other insects, such as caterpillars, aphids, and other soft-bodied insects.

While some cuckoo wasps may become pests in Louisiana, they are the most beneficial insects and help to keep other insect populations in check.

5. Double-Banded Scoliid Wasp

The double-banded scoliid wasp is a digger wasp found in the southeastern United States. It is found in many parts of Louisiana and is a beneficial insect that helps control pest populations.

This species has a black abdomen and thorax with two yellow bands, one on each side, and yellow legs. 

They are types of wasps in Louisiana, their wings are clear, and they have brown veins. The female double-banded scoliid wasp digs burrows to lay its eggs up to 1.5 feet deep.

In the burrow, the female will create several cells where she will deposit her eggs. 

These cells are made of mud, lined with grasses and other materials, and filled with food for the larvae when they hatch. The larvae feed on this food before pupating into adults and emerging from the burrow.

The double-banded scoliid wasp is an important species in the Louisiana landscape, helping regulate pest populations and pollination.

6. European Paper Wasp

21. Paper Wasp

Paper wasps are one of the most commonly seen types of wasps in Louisiana. They are recognizable by their black and yellow coloring, as well as their thin, elongated bodies.

These wasps build their nests out of paper-like material they create from chewed wood fibers, hence their name. 

They are not aggressive unless their nests are disturbed, and they primarily feed on insects such as caterpillars, flies, and aphids.

Paper wasps can be beneficial to have around as they help to control populations of these pesky insects.

When looking for paper wasp nests, pay close attention to areas near your home or yard and underneath eaves or other shelter areas.

The nests are usually gray or brown and typically take the form of an inverted umbrella or teardrop shape.

If you come across a nest, it is best to leave it alone, as the wasps can become aggressive if threatened.

If you need to remove a paper wasp nest from your property, it is best to call a professional pest control service for assistance.

22. Potter Wasp

The Potter Wasp (Eumenes fraternus) is one of the types of wasps in Louisiana commonly found near buildings, porches, and other structures.

These wasps build their nests out of the mud and then use their mandibles to fashion the mud into intricate, delicate works of art.

Potter Wasps can be identified by their long antennae, brownish-black bodies, yellow legs and wings, and the intricate patterns on their abdomens. 

In addition to building nests, these wasps also feed on various insects and spiders, which helps keep insect populations in balance.

These types of wasps in Louisiana benefit humans since they help control the population of pest insects.

24. Red-and-Black Mason Wasp

The Red-and-black Mason Wasp (Pachodynerus erynnis) is a species of wasp found in Louisiana. This species of wasp has a unique red and black coloration.

They are often found nesting in abandoned nests of other wasps or using materials such as paper, mud, and chewed wood to create their own. 

These wasps feed on insects, including aphids and caterpillars, and also consume nectar. This wasp species typically has two generations per year, with adults overwintering in the nest.

It is important to note that they can be aggressive if disturbed or threatened.

The Red-and-black Mason Wasp is typically found in wooded areas, gardens, and parks in Louisiana.

Regarding identification, these wasps have mostly black bodies with large red bands around their abdomen. 

They can also be distinguished from other types of wasps in Louisiana by their large size and long antennae.

This species of wasp is beneficial to the environment, as they help to control insect populations in the area.

25. Sand Wasps

When separating Sand Wasps from other wasps, large yellow bands and a long, tubular abdomen are useful characteristics.

Sand wasps, one of the types of wasps in Louisiana, are not particularly aggressive and only sting when provoked.

According to the Missouri Department of Conservation, sand Wasps may utilize humans as bait, hovering nearby to capture a fly interested in human sweat or food. 

Even while a Sand Wasp may appear angry when it flies close to someone’s face, its main concern is attacking a nearby fly, not the person.

Sand Wasps can be found inland and along beach fronts and dunes since loose, sandy soil is widespread over the continent, making good nesting places. 

Females are skilled at digging quickly, making tiny tunnels to house their eggs. The female begins by gathering eggs for the nest and then goes fly-hunting to find flies to feed her larvae.

Sand Wasps can help reduce fly populations by consuming Deer Insects and other invasive flies.

26. Scolid wasp

Female Scoliid wasps are not ashamed to use beetle grubs’ labor to their advantage to enhance reproductive success. Beetle grubs delve deep into the earth to consume roots and pupate.

The females locate a tunnel and sting the beetle larva to render it helpless. Then, next to the grub’s back, she vertically deposits a fertilized egg.

As soon as it hatches, the wasp larva feeds on the immobile beetle larva and grows and pupates before emerging as an adult wasp in the spring. Nothing of the grub survives.!

Adult males and females have different looks, despite having comparable markings.

The ragged yellow streaks on the black abdomen resemble far-off mountain ranges drawn on a night sky.

There are still more types of wasps in Louisiana that you should know about. Continue reading!

27. Short-Tailed Ichneumon wasps

Brown or reddish-brown short-tailed Ichneumon Wasp species comprise the majority.

Females still have shorter and less spectacular ovipositors because their abdomens are not as stretched as those of other Ichneumon Wasps.

Legs and long, wispy antennae have a light brown tint. Short-tailed Ichneumons, like moths, are drawn to lights and frequently visit residences and places of business close to fields or woodlands.

Almost all of the Short-tailed Ichneumon larvae Caterpillars are parasites of wasps. Using the ovipositor, females most likely affix a fertilized egg to a caterpillar. 

After hatching, a larva enters the caterpillar’s body and eats it from the inside out. In the procedure, the caterpillar perishes, but the wasp larva stays in the corpse to pupate. 

28. Spider Wasps

Wasps that chase spiders are known as spider wasps. This black and orange spider paralyzes jumping spiders by attacking them.

To hasten the transfer of a spider to its nest, the wasp may even rip off some or all of the spider’s legs. 

The wasp walks or flies the spider back to its home while holding it in its powerful jaws. It is recommended to give this species a wide berth because it can deliver a nasty sting, especially if a female is nesting.

This species can be found in woodlands, forests, and other hunting-friendly habitats.

Spider wasps use mud pots that Mud Daubers, another kind of wasp, have used and abandoned to build their nests.

A female places a fertilized egg with the immobilized spider in one of the pots. She fills the pot’s opening with mud or plant matter. 

As the wasp larva grows after hatching, it consumes the spider’s internal organs. Although the larva is parasitically carnivorous, the wasp adults switch to eating flower nectar.

We are gradually approaching the end of this list of the different types of wasps in Louisiana.

29. Ringed Paper Wasp

The Ringed Paper Wasp is a species of wasp native to the United States and Canada but can also be found in Louisiana.

This type of wasp is large and yellow-black with a distinctive ring on its thorax and abdomen. The female Ringed Paper Wasp builds a nest made of paper-like material and lays eggs in it. 

These nests can range in size from small, simple structures to large and complex colonies. The larvae feed on paper material and are tended to by the female until adulthood.

Adult Ringed Paper Wasps have a stinging ability but rarely sting humans unless threatened.

They are types of wasps in Louisiana that feed on nectar and pollen and help pollinate plants and flowers in their natural habitats.

30. Squarehead Wasp

The head of a Squarehead Wasp is best described as a rounded cube. Usually measuring 1 cm, this tiny flying insect is only long enough to sit across the pinky fingernail.

With most species showing vivid yellow bars near the “neck” and a yellow band just before the “waist,” the traditional black and yellow coloring is evident. 

Moreso, yellow bands can also be seen on the abdomen. There are also types of wasps in Louisiana with short, yellow antennas.

Legs are also yellow, with dark feet and black “thighs.” When resting or moving, the dark wings typically overlap and tuck back over the body.

Females build their nests in pliable twigs or rotting, soft wood. To provide her larvae with food once they hatch, she captures flies and stores them with her wasp eggs.

31. Thread-Waisted Wasp

Lastly, on this list of the different types of wasps in Louisiana is the Thread-waisted Needle-waisted Wasps, another name for wasps.

Although it seems unlikely, fluids can move through such a small center. They frequently hunt on and drink from blooms. 

Asters, Queen Anne’s lace, horsemint, and goldenrod are common plants to inspect. In certain lighting, the black body might appear blue.

The thorax features white patches close to the joints where the legs meet. They are swift in flight and have powerful jaws.

Female Thread-waisted wasps are found on flowers either mating, looking for caterpillars, or consuming nectar.

Wasps make a lot of effort to give the following generation a strong start. She digs a burrow and puts fertile eggs inside of it. She pursues, tackles, and stings a fat caterpillar, paralyzing but not killing it. 

The caterpillar is then dragged back to her burrow and set down close to her eggs.

To protect it from creatures that would devour her eggs and take advantage of all her hard work, she carefully covers the entrance of her burrow with dirt, debris, and pebbles.

The caterpillar is still alive but immobile as the wasp larvae feed on it after hatching until they pupate.

Conclusion

Louisiana is home to many types of wasps, some of which are beneficial to the environment, and some can be quite dangerous.

Wasps play a vital role in the food chain and can help control the populations of pests like caterpillars and aphids.

This article explored the different types of wasps in Louisiana and their specific roles in the environment.
