25. Sand Wasp
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, along beach fronts and dunes, since loose, sandy soil is widespread throughout 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, growing and pupating 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 Wasp
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 Wasp
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.
Moreover, 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.” The dark wings typically overlap when resting or moving and tuck back over the body.
Females build their nests in pliable twigs or rotting, soft wood. She captures flies and stores them with her wasp eggs to provide her larvae with food once they hatch.
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 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.
Louisiana is home to many types of wasps, some beneficial to the environment, and some 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.
