Most wasps build their nests from chewed up wood or mud!
Wasps are some of the world’s most diverse creatures as this category of insects has more than 100,000 species worldwide. While most people think of wasps as aggressive insects that live in large colonies, the vast majority of wasps are peaceful, solitary creatures. Although related to bees and ants, wasps are characterized by their slender, smooth bodies that have few hairs. They also have a narrow petiole or “waist” that attaches the abdomen to the thorax.
5 Wasp Facts
- Wasps are classified into two types: social and solitary. Most wasps are solitary, meaning they prefer to live alone, while social wasps live in colonies of up to 10,000 individuals.
- Wasps live all over the world, living on every continent except Antarctica.
- Their venom contains a pheromone that makes other wasps more aggressive when they smell it.
- Wasps can repeatedly attack because their stinger is not barbed like those of bees.
- In later summer, young fertilized queens will burrow into an old log or inside other structures where they hibernate as all other wasps die off. In the spring, these queens start new colonies.
Wasp Scientific Name
Wasps are insects that are members of the order Hymenoptera. Social wasps, the wasp species names that people are probably more familiar with, constitute about 1,000 species within the family Vespidae.
Yellowjackets, which include the eastern yellowjacket (Vespula maculifrons) and the southern yellowjacket (Vespula squamosa), are part of the superfamily Vespoidea, as well as the baldfaced hornet (Dolichovespula Immaculata). Wasp species names generally incorporate hornet for those that nest above ground, while yellowjackets refer to species that nest underground. Solitary wasps are also members of the superfamily Vespoidea, but are also members of superfamilies Chrysidoidea and Apoidea.
Wasp Appearance and Behavior
Many wasp species, particularly yellowjackets, have yellow and black markings, which is why many people commonly confuse them with bees. Although yellowjackets get their common name from their appearances, some subspecies have different colorations, encompassing almost every color. These insects can also be brown, metallic blue, and bright red, with the more brightly colored members part of the Vespidae stinging wasp family. Paper wasps are one of the more common species in North America, are similar to hornets and yellowjackets, and are generally brown in color. They are semi-social creatures that live in small colonies but do not have a worker caste.
Their bodies have pointed lower abdomens and a petiole, a narrow waist that separated the abdomen from the thorax. In appearance, they are much thinner than bees. They also have biting mouthparts and antennae with 12 to 13 segments. Most species have wings. In stinging species, only females have a stinger, which is essentially a modified egg-laying structure that pierces and inserts venom into the victim.
In the Northern Hemisphere, these insects become most aggressive from August to October as this is the time when their food supply changes and young queens have left the colony to find new mates. It’s also the time when they are most likely to attack humans. Wasps also emit a pheromone when they are threatened, which is why you should never swat this insect after you have been stung as this action will cause other wasps to attack.
Species range in size from just over a half-inch to 1.8 inches long. Some of the largest members are solitary wasps such as cicada killers and the striking blue-and-orange tarantula hawks, both of which can grow up to 1.5 inches long.
The executioner wasp (Polistes carnifex) has the most painful and deadly sting of all wasp species in the world. Central and South America is home to the executioner wasp, which is a type of yellow and brown paper wasp. However, the Schmidt Sting Pain Index also lists an attack by the warrior wasp as a Level 4 Pain, described as pure, intense, brilliant pain that can last for up to two hours. Most people recover after being stung by these insects, but those who are allergic to the venom can suffer significant side effects, even death.
All wasps build nests, and although their homes look similar to those constructed by bees, they are made of paper. They create their homes by chewing wood fibers to a pulp via their hard mandibles and then secreting the pulp into honeycomb shapes. Other species such as potter or mason wasps, called mud daubers, use mud to build their homes, which look like long tubes. Favorite places to build homes include basements, sheds, and other dark, cool areas – where you are likely to have seen a wasp nest.
Thread-waisted wasps of the Apoidea superfamily have more diverse nesting habits, as you’ll find them in wood and pithy plant stems as well as mud homes. Spider wasps build their habitat in rotten wood or rock crevices.
These insects are omnivores, meaning that they eat all kinds of food. Similar to bees, they prefer sweet foods such as nectar, honey, fruit, tree sap, and human food. Like bees, they often play a part in the pollination of plants in their search for nourishment. However, they also eat almost every pest that harms crops, including grasshoppers, aphids, flies, caterpillars, and even bees as well as other garden pests, making them invaluable partners in the propagation of fruits and vegetables. They will often travel as far as a half kilometer from their nests when searching for food.
Wasp Predators and Threats
These insects are preyed upon by many different types of animals throughout the world, including birds, reptiles, and amphibians. At least 24 bird species eat them, but they tend to hunt solitary species. Other insects that feed on them include praying mantises, dragonflies, robber flies, and even other wasps. Some mammals such as mice, rats, skunks, raccoons, weasels, wolverines, and badgers will also risk occasional wasp attacks to eat this insect.
People in Japan and Laos eat the larvae, which is considered a delicacy.
Wasp Reproduction, Babies, and Lifespan
The life cycle varies slightly among each species, with lifespan ranging from 10 to 22 days. Yellowjackets have a typical lifecycle that many other social wasps share. The lifecycle begins when a fertilized queen starts building her home, which is usually small at first. The first eggs hatch into female workers. Once these reach maturity, they continue building while the queen lays eggs and hatches additional workers.
Queens can lay eggs continually because they store sperm after mating with a male in the autumn. She uses the sperm repeatedly to grow her colony, but usually runs out of stored sperm by the end of summer or early fall. The new males in the colony develop from the unfertilized eggs the queen lays at the end of summer. Males leave to mate with new queens, after which they usually die. The worker females start dying in late summer and early fall too, leaving only the mated queens to survive the winter. Mated queens will then find a place to winter and remain dormant until the spring when they restart the cycle. Most queens only live one season.
Many, but not all, wasp societies have a caste system consisting of one or more queen, a few drones, and the worker females. The colonies produced exist in one or more layers of paperlike cells made of chewed plant material mixed with saliva and regurgitated by the insect. In some species, the queens devote the rest of their lives to egg laying and never emerge again.
Workers feed larvae a diet of masticated insects and other food, with caterpillars being a particular favorite. In autumn, workers construct larger cells for new queens, with larvae in these cells receiving higher amounts of food. Simultaneously, older queens begin to lay male eggs, with the drones mating with the new queens that will be the founders of the next year’s colonies. When the founder queens die, the workers begin to behave erratically until they all die off by the beginning of winter.
Solitary insects have a much different lifecycle. Generally, a lone female will mate and then prepare and provision one or more homes for her offspring, each containing cells for her young. The eggs hatch, with the larvae consuming the supplied food without leaving the cell. Following pupating, the new adult wasps emerge and seek mates. The males of most species have shorter lives and die after mating. The female goes on to continue the cycle.
More than 110,000 of this insect species have been identified and scientists believe that another 100,000 await identification. A recent study discovered 186 new species in a rainforest of Costa Rica. Thus wasps are not in danger of becoming extinct anytime soon.View all 31 animals that start with W
Wasp FAQs (Frequently Asked Questions)
What is a wasp?
A wasp is a narrow-waisted winged insect. While it is not an ant or a bee, it is part of the same taxonomical order.
Are wasps carnivores, herbivores, or omnivores?
Since they eat a variety of plant-based foods as well as other insects, wasps are omnivores.
How do wasps differ from bees and hornets?
The major difference between wasps and bees is that the latter use pollen to make and eat honey and have a thicker body shape. Bees also die when their stingers become lodged in a victim. Hornets are generally larger than wasps, are more colorful, and form colonies above the ground.
Do wasps die when they attack you?
Unlike bees, wasps don’t die when they attack you because their stingers don’t become lodged in your skin. In fact, they can attack repeatedly
How do you treat a wasp sting?
If stung by a wasp, wash the affected area with soap and water to remove as much of the venom as possible. Apply ice to the wound to reduce pain and swelling. However, if you are allergic to wasps, you will need to seek medical attention immediately.
How do you get rid of a wasp nest?
To get rid of a wasp nest, approach the colony slowly and quietly at night with a plastic garbage bag. Cover the nest with the bag and then slowly detach it from the tree or wall where it is attached. Firmly seal the bag and then place it in a garbage can with a tight-fitting lid.
Do wasps swarm?
Only bees swarm, although if you disturb a wasp and it senses danger, it will release pheromones that call other wasps and cause them to become aggressive.
Do wasps make honey?
No, wasps do not make honey, but they assist in the pollination of plants in a manner similar to bees.
Do wasps make honeycomb?
Wasps don’t make honeycomb. However, in a sense, wasps do make a honeycomb-like structure, but they are not made of wax. Their honeycomb-shaped colonies are made of masticated wood.
How many individuals are in a social wasp colony?
Although they start small, social wasp colonies can have more than 10,000 individuals at the height of summer.
How many eggs can a queen wasp lay?
Although not as prolific as bees, queen wasps can lay up to 100 eggs per day.
