Fire Ant Life cycle A new generation

After a winged male ant mates with a virgin queen, he dies and she finds a good nesting site. After she locates one, she sheds her wings and begins digging a chamber where she will start her new colony. When it is finished, she begins to lay eggs.

The queen ant lies in the nest on top of hundred of eggs and larvae while workers bring food to her.

The life of an Ant

An ant begins its life as a white or yellow egg. This egg is so tiny that it is smaller than a piece of dust. After a few weeks, a small, white worm comes out of the egg. This worm is called larva.

The legless ant larva is helpless. Work ants feed and take care of the larva. The larva eats a lot of food and grows. It sheds its skin many times as it grows. When a larva stops growing, it turns into a pupa and rests. In time, a pupa turns into an adult ant.

Setting Up house

A queen ant is a female that is born with wings. When a queen becomes an adult, she flies away from the nest to start a colony of her own. After she finds a male, the two mate. A short time later, the male dies.

The queen then finds or digs holes in the ground in which to live. She will stay inside her nest the rest of her life, so the queen no longer needs wings. She bites or breaks them off. Then the queen lays eggs in her new nest.

Eggs and Larvae
Queen ants mates with males and then lay eggs. An ant changes from egg to larva to pupa to adult. Ants begin life as white, rounded eggs. Adult ants keep eggs clean.

Depending on weather, most eggs become larvae in only a few days. Larvae are white and have no eyes or legs. They grow and molt, shedding their exoskeleton. Some larvae make silk cocoons to grow in while they are pupae.

Pupae and Adults

Pupae do not eat or walk. Not all pupae grow in cocoons. Some look like white adults when they are pupae. After about two weeks, pupae become adults.
Adult ants are queens, males, or workers. Males die after mating. All workers are female and have many jobs. They work together to fix nests and find food. Soldiers are special workers that protect nests.

When the mating flight is over, the ants land. The males die. Some queen ants return to their old colony to become extra queens there. Most find a new place to star their own colony.

After this mating flight, the queens will be able to lay eggs for their whole lives.

Only ants born with wings can mate

The wedding flight
On a warm day, the flying ants finally leave the anthill and take to the air. There are so many, they look like a thick cloud in the sky. The ants mate during the flight. Afterwards, the males die, and the females’ wings fall off. The princesses are now ready to be queens, and they will never fly again.

A new family

A young queen digs a hole in the ground and disappears to lay the first eggs of a new ant colony. The queen must spend several months alone until her first babies are born. She can not get any food for her self, so she lives off the nutrients in her wing muscles. Her first children will find food for her and build an anthill for their colony.

As soon as a new queen loses her wings, she disappears underground.

While the eggs develop, she lives off her body fat or even eats some of the eggs she lays.
After a few days. The eggs hatch into worm – like creatures, called larvae. The queen feeds them with her saliva and food that she has chewed. After a few weeks, the larvae become pupae. They spin silk cocoons around themselves and break out after two or three weeks, when they are full- grown adult ants.

The first adults to develop are worker ants.

From this moment on, the queen does nothing but lay eggs.

The workers take over all the work in the colony. One of their most important jobs is making their home, nest, bigger so there is room for the colony to grow.

Larvae
A queen licks her eggs to keep them clean. In about 20 days, they hatch and enter the second stage of ant life. This is the larva stage.

Ant larvae look like small white worms. They do not have any legs and can not see. while the workers help the queen, soldier ants protect the nest.

Pupae

Ant larvae cannot take care of themselves. The queen and nurse ants continue to care for and feed them. After about a month, the larvae are ready to enter the third stage. This is the pupa stage.
Some ants spin a cocoon around their bodies. Other does not. During the pupa stage, the adult body forms. It takes about 3 weeks for the adult ant to fully form. Then it comes out of its cocoon. At first, the adults are pale. But their color darkens quickly.

Mating

When the new adult comes out of the nest, it is time for them to mate. The male ant’s main job is to mate with the queen.

During this early adult stage, many kinds of ants have wings. After mating, males usually die. Females lose their wings. Other females that have mated become queens.

The tiny white eggs will develop into worm – like larvae. Workers feed larvae seeds or bits of dead insects that have been softened by the workers’ saliva. A month later, the larvae turn into pupae and start to look more like ants. Finally, the adult emerge.

They often look very pale at first but turn their final color in a few days. Most newborn ants are workers. About once a year, however, the queen lays special eggs that grow into new queens and males. Unlike the workers, these ants are born with wings in the wild; they use their wings to fly high into the air to mate.

Development

Ant reproduction depends on the queen. The queen lays millions of eggs in her lifetime, although not all survive to adulthood. The large number of eggs ensures that the colony will survive the many hazards that face ants: Predators, floods, poison, and drought, for example.
Most of the eggs become female workers, which are much like the queen except they cannot lay eggs. The queen can lay male eggs and female eggs when the colony needs to split. Her body changes its chemical make up to produce males. A chemical process occurs among the female worker eggs, allowing the females to become potential queens. Both the males and the females usually have wings.

The ant’s eggs are so tiny that they are almost invisible, but cocoons may be small or large. Depending on the size of the baby ant wrapped inside.

Newcomers
The queen lays thousands of eggs, and each egg holds a baby ant that looks like a little white worm when it hatches. The baby is called a larva. It grows very quickly.

When the larva is ready to become an adult, it spins a cocoon around its body and changes shape inside. When the baby comes out, it looks just like an adult ant.

Posted in Reproduction

The ant can be a nuisance when it gets into a person’s house, but it is an important protector of the environment. The ant eats decaying plants and animals and also living insects that destroy trees. The ant’s tunnels help loosen the Earth, making it easier for plants to grow.

Living with Ants

Ants are an important part of nature. As they dig and move dirt, they mix air into the soil. This helps plants grow. Ants also move thousands of different plant seeds, which helps these plants spread to new places.

Some ants eat small insects that hurt crops. Instead of using insecticides, farmers in China put weaver ants in their fruit tree fields to keep them safe from pests. While some ants are helpful, others are not.

Leaf cutter ants take leaves off young fruit trees. Even day they destroy crops valued at millions of dollars.

Fire Ant Defense: Keeping Safe
Fire ants are tough and also almost impossible to get rid of. With all of the damage they do to animals, other insects, and plant life, as well as the continuing danger to humans, they are an insect that needs to be, at the very least, controlled.

However, that is a big challenge. In fact, after years of trying more than seven thousand different pesticides and other chemicals and spending millions of dollars, experts have decided that it is impossible to eliminate fire ants. There is little question these insects need to controlled; at their rate of growth and their aggressive nature, they will become an even bigger problem if not restricted in some way. In some places throughout the Southern United States and parts of Australia, people are already having trouble walking out their own backyards or field without fear or attack. And playgrounds are being abandoned and camping is becoming too risky.

A crop sprays pesticides on field. Only the strongest pesticides can control fire populations.

Possible Benefits

One reason that some experts believe fire ants should not be totally eliminated is that fire ants actually do some beneficial things, too. They eat a number of insects that are also real troublemakers. For instance, fire ants help sugarcane growers by eating some of the pests that can ruin the crops. In cotton fields, fire ants kill off up to 85 percent of the boll weevils and their eggs. Fire ants also eat mosquitoes, which bother both humans and livestock. They also eat vast amounts of other pests such as lone star ticks and termites. While these things do not make up for the danger that fire ants bring to an environment, they do prove that they are not totally without benefit. The effects of fire ants on the environment are complex, and researchers continue to study them.

Cotton fields benefit from fire ants that eat crop – killing pests.

These leafcutter ants live in the Amazon in South America.

The painful sting of fire ant is both a nuisance and a health threat to humans.

Posted in Behavior

Fire ants have been in United States for only about seventy years. They first came here from South America. In That short period of time, they have spread throughout thirteen different states in the South and Southwest. In the last few years, they have also manage to spread into Puerto Rico and Parts of Australia. They show little sign of stopping there. In stead, they just keep marching farther across the map because no one has figured out how to get rid of them yet.

Another advantage that fire ants have is that they are happy to set up housekeeping almost anywhere. Their mounds can be found in everything from orchards and golf courses to washing machines and air conditioners. By not being particular about their neighborhood, they make it challenging for people to predict where they might be living.

Ants in the World

Many ants build nest after rains. Building is easier when the soil is wet and movable.

No Place like home

Fire ants are not picky about where they live or how big their nests are. Although they prefer sunny, open areas, they will start a nest almost anywhere. Some of their favorite spots are
Fruit and vegetable crops, nurseries, vineyards, hay fields, orchards, parks, golf courses, and lawns, where they are know to build large colonies. However, they are also attracted to electricity. They have been known to nest in very small areas such as computers, air conditioners, washing machines, and cars. Because they like to chew on the electrical insulation found there, they often end up causing short circuits and fires.

Ant Habitats

Their homes are networks of dark, curving tunnels and small rooms. Busy places that house up to one million family members. All build without, tools or blueprints, by one ant helping another. Ant colonies live in nests. In the wild, these nests can be found in tree branches, rotten logs, and even telephone poles. But most ants live in the dirt. People around the world have studied ants and their nests for thousands of years.

Home sweet Home

Have you ever noticed a hill of dirt in your backyard? Look closely and you might see ants crawling in an out of a small hole on top of the dirt pile. This hole is front door to an ant’s home. Below the door are many rooms you cannot see.

Ants dig holes underground to make a nest. They dig tunnels between the rooms to make the nest bigger. A larger group of ants living together in one nest is called a colony. Not all ants live underground. Some colonies live in pieces of dead wood or old leaves.

One incredible thing about ants is that they “farm” certain kinds of insects for food. They do this much the same way that farmers take care of cows for their milk.

Small, green insects called aphids make sweet liquid called honeydew. Ants actually herd rows of aphids and collect this honeydew by tapping them with their antennae. They bring the liquid back to the nest to share with their fellow ants. In exchange, ants protect aphids from insects that would eat them. Ants do this with a few other types of insects, too.

Honeydew is the feces of aphids and some caterpillars and is a much – prized feast for several species of ants. Black garden ant workers make sure there is plenty of honeydew for their colony – they farm aphids. This program works out well for the aphids, too. The ants protect the aphids from predators. The aphids eject honeydew to feed the ants.

Farming

Just as humans raise cows for milk, some ants raise aphids for plant syrup. The aphid often sucks too much juice from a plant. The excess syrup falls in small drops from the aphid’s body. The farmer ant sucks up the syrup and stores it in a cavity in front of its stomach. Then the ant returns to the colony with its family.

Living with ants
Ants are always looking for food. They often raid people’s kitchens and raise aphids on the plants in people’s gardens.

It can be hard to get rid of an unwanted ant colony. Most ants hide deep in the ground if they sense danger and come out only when they feel safe again.

The oldest worker ants generally find food for the colony. These ants are called foragers. Forager ants do not live long because they often face enemies and bad weather. They must also carry pieces of food that weigh up to 20 times their body weight.

Most ants eat parts of plants, such as seeds. Some ants eat dead insects or spiders. Certain types of ants drink sweet juice from flowers, called nectar, or tree sap. An ant has four tiny sticks near its mouth called palps. Ants use palps to taste food and push it into their mouth.

The main problem with fire ants is that they like to eat and they are not at all picky about what is on the menu. They also are not shy about going after their food. Instead, they are very aggressive, and often when they move into an area other small animals and insects end up either moving out – or getting eaten. This determined and hungry attitude means trouble for many of the leaves, stems, and roots of plants in the area, as well as even bigger trouble for tasty bugs such as termites, spiders. and bees. The menu choices do not stop there, however. Fire ants will happily eat bigger meals such as birds, mice, and snakes, and even large animals such deer, squirrels or rabbits. They attack the most vulnerable parts of the bigger animals, including their eyes, nose, and mouth. While the animal may run and try to escape, it rarely can brush off the ants and stop the stinging.

All ants share food in much the same way. A group of workers gather the food and feeds it to the rest of the colony. To do this, ants have two stomachs. One is a storage stomach, called the crop. Workers squeeze all the liquid out of the food they eat and spit out the hard bits. They keep the liquid food in the crop. Some of this passes, drop by, into the second stomach to feed the ant. Most stays in the crop to fed to other ants.

Mouth to mouth

Back at the nest, hungry worker ask for food by opening its mouth and stroking the food gathering ant’s head with its antennae. Then both ants touch mouths. The food gatherer spits up a drop of food from its crop and passes it to the other ant’s mouth.

Finding food

Ants also help each other find food. When an ant finds a big piece of food, it may return to the colony to get other ants. Some species of ant leave a trail of scents, which they use to find their way back to the food.

Other ants use their antennae to feel stones and other objects to help them remember the route. When the ant gets back to the nest, it taps and prods other ants to get their attention so some of them will follow it back to the food.

Many Kinds of Food
Ants eat many of food. They drink juices from plants and “milk” certain kinds of insects for their liquid. They also eat caterpillars, worms, beetles, bees, termites, and many other kinds of insects.
Some ants eat leaves, fungus, fruit, seeds, or honey. They like foods that are sweet and will eat many types of human food.

In a colony, different kinds of have special jobs. Workers ants are female. They often work together to capture a large meal and carry it back to the nest.

Some ants eat insects and animals. Ants eat beetles, termites, flies, spider eggs, and earthworms. Ants even eat other ants.

Other ants eat other ants.

Other ants eat plants and fungi.

Harvester ants gather and eat seeds.

Leaf – cutting ants cut off pieces of plants. They then carry them to their nests. Later, fungi will grow on the plants. Fungi, such as mushrooms, have no leaves, flowers, or roots, Leaf – cutting ants eat the fungi.

A Group of ants find a dead fly. Later they will carry it back to their nest and eat it.

Most ants are omnivores. They can eat both plants and animals, mostly insects. Ants use the protein they get from eating insects to grow and to keep their bodies health. They also collect sweet plants juices from the nectar in the center of the flowers of sugary sap from plant stems. Sweet foods are an important source of energy.

Sweet tooth

Many ants get their sugar from aphids or other insects that feed on the sap in plant leaves and stems. These plants – sucking insects take in more sap than they need, and some of this may leak out of their bodies. Ants know that if they tap or rub an aphid’s back, it will release a drop of this syrupy “honeydew.”

Aphid Herds
Like farmers, many ants keep their own aphids so they don’t have to go looking for them. This is so common that the aphid is sometimes called “the ant’s cow”. Ants care for aphids eggs in spring and keep the aphids that hatch out. They may even build “barns “of sand grins or soil around the aphids for protection. Some ants carry their herds of aphids to leaves rich in sap so they can eat!

How do ants catch other insects?

When a group of ants comes across insects they like to eat, such as a caterpillar, they surround it. Some ants bite their prey and then spray the wounds with formic acid. This is a kind of poison that paralyzes the prey so it cannot get away

Other ants sting their prey to paralyze it. Workers carry the food back to the nest if it is small. If it is large, soldier ants bite the prey into pieces using their big mandibles, they workers carry the pieces back to the nest.

Every single day, fire ants are out exploring the area around their mounds in search of some food to take back and share with the rest of the colony. Often these foragers are on their own; sometimes they hunt in teams. If an ant finds more food than it is able to carry, it will often lay down a chemical trail for the others to follow so that they can help bring it home. This chemical they use to make the trail is called a pheromone and it comes from a special gland in their abdomens. Researchers are not sure just what information is contained in this message. Some believe it is just the location of the food, while others suspect that it has information about what kind and how much of the food is out there.

Often, a fire ant food hunt will take them into public areas such as parks, fields, and even near high ways. There is no way to be sure just what one specific fire ant was doing in the city of Plano, Texas in 1991. It might have been hunting for food or getting ready to lay down a trail, but no matter why it was there, it was about to cause trouble for one unsuspecting young boy.

Another reason fire ants are taking over is that they are not picky about what they eat. They are omnivores and can eat plants, insects, fungus, bacteria; small animals- even other fire ants.
Fire ants eat plants and plant parts such as leaves, stems, sap, bark, fruit, vegetables, nectar, and roots. They also eat animals such as snakes, lizards, frogs, mice, turtles, and birds. They have been known to chase brooding hens and quails off their nests to get to the bird’s eggs. These ants will also eat springtails, ants, bees cut worms, beetle and boll weevil grubs, termites, spiders, insect feces, and other fire ants. They will eat their nest mates, including dead queens, dying adults, eggs, larvae, old skin, and excretions. They are thorough eaters too – when they eat a tick, for example, they begin by biting off its blood – filled legs.

When more workers arrive, they eat the blood as well as everything else inside. When they are done, all that is left is an empty shell.

If it seems like all fire ants do is eat, that is somewhat true. Experts estimate that thirty – six mounds on one single acre of land consume an amazing thirty- five pounds of insects and sugar every single week during the summer season.

The queen and the brood ants inside a fire ant mound are almost always hungry. This keeps the forager ants, the ones whose job it is to hunt for food, very busy. Every day about one- fifth of the entire colony leaves the mound to search for something to bring back to the nest to eat. It is not an easy job. The weather can make the trips deadly if it is too hot, too cold, or if it is start to rain. Ants who live in southern areas like Texas where the summer day time temperatures can rise to well above a hundred degrees often wait until nightfall to begin their hunting. About half of the time, despite their hard work, fire ants return to nest without having found anything at all to eat.

Determined to do their difficult jobs, these forager ants cover areas up to one hundred yards away from their mound’s many long underground tunnels. They explore a number of different places and have been known to climb up more than thirty feet in a tree in search of anything from insect droppings left o n leaves to other tasty treats. Parks are often a favorite place for fire ants, too. Tourists and other visitors often drop crumbs of food there and leave papers behind that still have an ant- size feast on them.

Forager ants feed their queen. Finding food for an ant colony is a very tough job.

Posted in Food

Because the Queen and the brood are almost always hungry, the forager ants must start on their daily hunt for meal. Quietly, about one – fifth of the colony leaves the nest through the side tunnels that stretch out in every direction from the mound. Some ants do their hunting during the day, while others choose the nighttime, especially if they live in Texas, where the daytime temperatures can easily climb 100 degrees Fahrenheit.

Foraging is a dangerous job. While searching for food, these ants are out in the open where enemies can attack them or where the weather can make life difficult. If it is too hot or cold, they can die while looking for dinner. Rainstorms can be deadly, too. Most of the time ant foragers will look for food by themselves, but now and then they will move together as search party. Their search field can reach up to one hundred yards away from the nest. Foragers cover the area in loop pattern, ending up back where they started. About half the time these ants come back home to the nest with nothing, despite their hard work. Fire ants have been known to climb more than thirty feet up a tree to get insect droppings on leaves or to burrow their way through fresh dung to collect the maggots that are buried there. They do find food, fire ants harvest it quickly. Experts have put out bait to attract fire ants in order to study them; it usually takes less than ten minutes for the ants to detect it. It is not unusual for workers to make fifty trips back and forth to the nest in just an hour.

Eureka!

Foragers must process the food before bringing it back to the nest. They will take the juice or liquid from it, eat part of it for themselves, and store the rest of it, in one of their two stomachs, called crops. An ant with a full abdomen looks swollen and slow. Rarely is solid food brought back to the colony because most fire ants do not have mouths big enough to eat. Only a certain group of larvae, the oldest group, are able to process solids at all. The rest of the ants are fed liquids from the worker ant’s crop. An experiment in a science lab in 1997 showed how efficiently fire ants could suck all the liquid from their prey.
A hard – boiled egg was reduced to nothing in matter of a few hours.
Once they have secured their find, the foragers scurry back to the nest. There they regurgitate the food and feed it to the reserves. The reserves, in turn, do the same thing and feed part of the food to nurses. Next, it is time for the young larvae to eat – they suck it strait out of the nurses’ mouths. The process of passing food from one to the other is called trophallaxis.

By following a pheromone trail, the ants locate a large food source and help take it to the nest.
Sometimes fire ants get really lucky and they find so much food in the same place that one or even several ants are not able to carry it all.

When this happens, they call for help with her chemical trail for ants back home follow right the food. Sometimes the fire ant will cover up the trail with dirt to keep it safe. Because the trail can be blown away by breezes – Sometimes in as little as two minutes – the ants are never confused by old trails. They follow only the freshest ones that they can still detect. This chemical, called pheromone comes from a gland in their abdomen. Some experts think it just tells the colony the location of the food. Others believe that it also gives information about the quality and quantity of the food source. Obviously there is some secret information in the chemical trail; the further away the food is, the more ants that respond. There is little doubt, however, that one message it is sending is, “hurry up! I found a fest and I need help bringing it home!”

Fire ant foragers are even small nutrition experts. If their nests are lacking in one or two important nutrients, they will somehow recognize that and adjust their searches for food to bring home more of whatever food the colony most needs.

The largest ant is the soldier of the Australian bull ant, which is over one inch (2.5 centimeters) long. One of the smallest ants is the grease ant. It is only about the size of the period at the end of this sentence.

Brainy bugs
Ant’s brains are larger for insects. However, it would take 40,000 ant brains to equal the size of one human brain

Flood Damage
In Malaysia, some ants make nests in hollow bamboo stems. During heavy rains, water fills the nests. Workers drink the water and then hurry outside to let the water pass out of their bodies. They repeat this for hours.

Ants help other ants in their colony to survive big changes. These army ants are carrying pupae to a new home.

Did you know?
Ants’ closest relatives are bees and wasps. Ants are not related to termites other than both species are insects! Several ant species such as matabele ants, regularly raid termite nests for food.

A queen ant can live as long as 30 years.

Mans and Ants
Humans have a mixed relationship with ants. We admire the ants for their work style, but we don’t want them in our houses or our food. A trail of ants marching by carrying the food they scavenged fascinates us as long as they are not ruining our picnic.

Humans need to understand that ants provide valuable services in the natural world. They turn over the soil and distribute seeds. Ants also pollinate some fruity crops and plants. We need to understand that while Earth can survive well without humans, it would not survive without ants.

Ants fulfill an interesting role controlling pests. Third – century Chinese merchants sold ant nests to farmers to safeguard citrus trees. The ants warded off caterpillars and leaf – eating insects that might damage the flowers and reduce the production of fruit.
