How many ants are there in the world? Myrmecologists, or ant biologists who get paid to think about ants, estimate that there are one quadrillion ants on the planet. That’s 1 followed by 15 zeros, or one million billion if you can imagine it. That’s a large number of ants! They come in over 14,000 species and subspecies, with new ones being discovered every year.
How Many Ants Exist in the World?
Based on a one percent idea of the amount of all live insects on Earth at any given time, the population of ants was predicted to be ten thousand trillion in 1964. Ant experts have discovered 290 genera, 21 living subfamilies, and over 12,500 species of ants, all of which differ substantially in behavior and anatomy.
Given the vast number of unidentified and undescribed species, the list is far from complete, and the total number of species could surpass 30,000. Cataloging at the species level can be difficult, and it depends on the level of taxonomic research that has been conducted geographically.
Additional information about ants is being unraveled as taxonomic techniques and knowledge progress; as a result, more ant species will be identified, recognized, and formally described shortly.
Which Continent Has the Most Ants?
The majority of ant distribution studies (abundance and richness) were limited to certain geographic areas. Nearctic, Neotropic, Palaearctic, Afrotropic, Indomalaya, Australasia, and Oceania are the seven biogeographic areas, which follow the traditional partitioning.
Madagascar was separated from Afrotropic due to its high endemism level, resulting in the formation of the Malagasy area.
With 128 documented lineages, the Neotropic and Indomalaya biogeographical regions have the most ant genera among the seven biogeographical domains. In terms of endemicity, the Neotropics were home to 52 of the 290 genera recognized, or 41%.
| Biogeographic Region | Total Genera | Endemic | Endemic Genera (%) |
|---|---|---|---|
| Neotropic | 128 | 52 | 41% |
| Indomalaya | 128 | 24 | 19% |
| Australian | 115 | 30 | 26% |
| Afrotropic | 88 | 31 | 35% |
| Palearctic | 82 | 10 | 12% |
| Malagasy | 47 | 5 | 11% |
| Nearctic | 73 | 2 | 3% |
Which Country Has the Most Number of Ants?
Australia now maintains the record for having the most known ant species, with over 1,000 species unique to the continent.
Which Continent Is the Only One to Not Have Ants?
Except for Antarctica, where the average annual temperature ranges from -10°C to -60°C, ants can be found on every continent. In Greenland and Iceland, no ant species have been discovered.
Because ants have a hard time surviving in cold and rainy areas, temperature appears to be one of the most important abiotic elements controlling their spread. Greenland is located in the Arctic, where the average temperature reaches 10°C. In the summer, the average temperature in most places of Iceland is around 10°C.
What Is the Ratio of Ants to Humans in the World?
The world’s population is currently estimated to be around 7.9 billion people, with China having the biggest population of around 1.4 billion people and Vatican City having the smallest population of only 800 people.
The total number of ants on the planet is estimated to be roughly ten thousand trillion, implying that each human has 1.2 million ants. Similarly, this means that for every Chinese person, there are 7.1 million ants and that there are considerably more ants on Earth than there are Vatican City residents.
Are All the Ants as Heavy as All the Humans on Earth?
Ants are tiny insects, measuring as little as 1/16 inch in length (2 mm). The weight of the animals varies according to the species. A worker ant would weigh between 2.2E-6 and 1.1E-5 lb on average (1 to 5 mg). The typical human body mass, on the other hand, is roughly 137 pounds (62.0 kg).
As a result, ten thousand trillion ants would weigh 1.1E11 pounds collectively, whereas 7.9 billion humans would weigh 1.1E12 pounds. As a result, the overall mass of humans on Earth is ten times more than that of ants.
How Do You Weigh an Ant?
To calculate an ant’s weight,
Step 1: First weigh a container with an electronic balance.
Step 2: Fill the container with a known number of ants and weigh the new weight.
Step 3: Subtract the empty container’s weight from the total weight of the ants and container.
Step 4: To calculate the average weight of each ant, divide the total weight by the number of ants.
Summary:
Ant experts have discovered 290 genera, 21 living subfamilies, and over 12,500 species. Australia now maintains the record for having the most known ant species. Madagascar was separated from Afrotropic due to its high endemism level, resulting in the formation of the Malagasy area.
How Long Have Ants Been on the Earth?
The study of ant evolution is a constantly evolving field of study. Ant remains were discovered over 100 million years ago, during the Cretaceous period. Nonetheless, in the Late Cenomanian, the oldest unequivocal group of ants was discovered 95 million years ago.
Divergence dating methods, on the other hand, reveal that ants may have evolved between 140 and 168 million years ago or 115 and 135 million years ago. Ants were discovered to have a common ancestor with bees and wasps in this research.
Furthermore, their nesting and foraging habits were found to have a significant impact on their evolution into modern ants.
How Many Ants Are There in An Ant Colony?
The number of ants in a colony varies depending on the species and location. The majority of colonies have between 50,000 and 500,000 persons, while some have millions. Ants can also be observed crawling around your house or backyard throughout the summer when their populations tend to grow due to the warmer weather conditions, which suit them better than older ones.
The social ants are those that live in colonies. Solitary ants, on the other hand, do not have this luxury and must fend for themselves.
What to do if ants live in your house?
Swarms of tiny insects may occasionally crawl all over your furniture, which could indicate that their population has exploded since they’re reproducing at much greater rates than usual. However, there’s no need to contact pest control because these colonies will eventually die out as a result of overproduction.
Biggest Ants on Earth
The ants of the genus Dinoponera are the world’s largest, with total body lengths ranging from 1.18 to 1.57 in (3 to 4 cm). Dinoponera is one of 52 endemic genera found in the Neotropical region. They are members of the Ponerinae subfamily and can be seen foraging in a variety of environments throughout South America.
Formicium giganteum were the largest ants that ever lived on the planet. It’s a massive carnivorous ant with a body length of 2.2 inches (5.5 cm) and wingspans of 5.1 inches (13 cm). These pants first appeared in the early Eocene, between 50 and 55 million years ago.
Summary:
Ant remains were discovered over 100 million years ago, during the Cretaceous period. The ants of the genus Dinoponera are the world’s largest, with total body lengths ranging from 1.18 to 1.57 in (3 to 4 cm).
Interesting Facts About Ants
1. The Asian Weaver Ant Can Carry 100 Times Its Body Weight
Weaver ants (Oecophylla smaragdina) can carry 100 times their body weight, whereas certain ant species may carry more than 10 to 50 times their body weight. In Australia, Southeast Asia, and the Western Pacific Islands, these ants can be found.
Arboreal weaver ants are recognized for their unusual nesting style. Worker ants build nests by weaving together leaves of various shapes and sizes, which are held together by silk produced by larvae.
An ant’s body is divided into three sections, similar to that of other insects: head, thorax, and abdomen. The larger neck muscles of ants’ thorax, particularly of worker ants, are thought to be responsible for this remarkable capacity.
Furthermore, these strong neck muscles allow worker ants to not only carry preys that are heavier and larger than their bodies but also to maintain balance when returning to their nests with their prey or food fragments.
2. Ants Can Live For Decades
Unlike many ephemeral insects such as mosquitoes and house flies, ants, particularly queens, can live for over a decade.
In a laboratory, Lasius, sometimes known as the black garden ant, has the longest lifespan of any ant. A German entomologist named Hermann Appel kept the queen of the black garden ants in captivity for 28 years and nine months.
3. Ants Can Survive for an Entire Day Under Water
Ants, like other animals, require oxygen to live. As a result, they are more prone to drown when their nests are inundated and their colonies are submerged for long periods.
Formica ants, on the other hand, can tolerate being underwater for up to two weeks. This is feasible because ants will enter an anesthetic state in which their oxygen intake will be reduced by up to 20% of their normal intake.
4. Ants Don’t Have Lungs
Ants, unlike humans and other creatures, lack lungs. Instead, oxygen enters their bodies through microscopic holes in their thorax and abdomen. Spiracles are the name for these openings.
Ants have nine or ten pairs of spiracles that allow oxygen to enter and carbon dioxide to escape their bodies, depending on the species. Once oxygen reaches the spiracles, it diffuses throughout the ant’s body via the tracheal tubes, which are respiratory ducts.
5. Ants Are Farmers
Leafcutter ants (Atta cephalotes) are farmers who use their mutualistic relationship with fungi to create food in their nests. This partnership helps ants to survive, and maintain their colony, and the queen starts new colonies.
While humans are thought to have begun farming 12,000 years ago, ants have been cultivating for 45 to 65 million years, making them the world’s first and oldest farmers. This marked the transition from hunter-gatherers to subsistence farmers, just as it did for humans.
Summary:
Ants can carry prey that is heavier and larger than their body weight. Ants can also maintain balance when returning to their nests with food fragments. Ant queens can live for over a decade, and the black garden ant has the longest lifespan of any ant.
Frequently Asked Questions:
Following are some of the important questions:
1: Do ants outweigh humans?
"Individual workers vary in weight from 1 to 5 mg depending on the species. When all ants in the world are added together, they weigh nearly the same as all humans." The computation by Wilson and Hoelldobler is based on the assumption that the average person weighs a million different ways more than the average ant.
2: How many ants would lift a human?
As a result, that large ant can only carry roughly 1/4 gram. An ounce is 1/16th of a pound, and a gram is 1/28th of an ounce… As a result, many hundred ants would be required to pick up each pound of the person.
3: How many ants are there in the world in 2022?
Myrmecologists, or ant biologists who get paid to think about ants, estimate that there are one quadrillion ants on the planet. That’s 1 followed by 15 zeros, or one million billion if you can imagine it.
4: Do ants have blood?
Ants do have blood, however, it’s referred to as hemolymph. It is distinguished from the blood by the absence of red blood cells and hemoglobin. Because ants’ blood enters the body through the spiracles, they don’t need to transport oxygen across their bodies.
5: Do ants sleep?
Yes, they, do but not in the way that we think of sleep. In their 1983 study of insect sleep patterns, James and Cottell discovered that ants had a cyclical pattern of resting intervals that each nest as a group observes, with each resting period lasting roughly eight minutes in any 12 hours.
6: What is the deadliest ant?
During an attack, the bulldog ant got its moniker for its ferocity and determination. It is highly aggressive and has little fear of humans, stinging multiple times in rapid succession and injecting more venom with each bite.
7: Are ants stronger than elephants?
With a body size ranging from 0.75 to 52 millimeters, ants are widely known for their capacity to work together, but it is their agility, strength, and endurance that attract the attention of people with varying levels of knowledge.
8: How heavy can ants carry?
It has been documented that some species of ants may carry twenty times their own body weight. If a person could lift twenty times their own body weight, then they would be able to lift 4,000 pounds.
9: Are ants stronger than humans?
When it comes to strength, all ants combined could lift 22 trillion pounds, enough to lift and carry the entire human race on their backs. Humans, on the other hand, can only carry 1.1 trillion pounds, which is sufficient to move 100,000 trillion ants.
10: Do ants have hair?
Ants have hair on their body, as do many other arthropods. These hairs, called setae in technical terms, are related to the nervous system and fulfill sensory functions.
Conclusion:
Ant experts have discovered 290 genera, 21 living subfamilies, and over 12,500 species. Australia now maintains the record for having the most known ant species. Madagascar was separated from Afrotropic due to its high endemism level, resulting in the formation of the Malagasy area. Ants are tiny insects, measuring as little as 1/16 inch in length (2 mm). A worker ant would weigh between 2.2E-6 and 1.1E-5 lb on average (1 to 5 mg).
