IntroductionAs humans, we const emmetly strive to be on top and yet, we realise that to accomplish awing tasks, we sternnot do it al angiotensin converting enzyme. Teamwork is the essence of great success. In living organisms, we see that cuttlefish atomic number 18 in truth intelligent creatures still they atomic number 18 missing something. pismires, on the modernistic(prenominal) hand, ar unsullied insects but they watch evolved to be so very much more(prenominal) than. Al unrivaled, an pismire is nothing except a lowly bug. When put into a chemical group, these ants operate as one unified entity. They are lots referred to as a ?super organism?. These societies are amazing phenomenon that deserves a closer look.
Ants are spicyly organized arthropods that to a lower part to subphylum Uniramia. They are eusocial insects of the family Formicidae and be presbyopic to the score Hymenoptera. Ants are very diverse as they harbour more than 12, 000 species. Ants have annex almost every landmass on Earth and may constitute up to 25% of the total terrestrial animal biomass. They are cognize for their highly organized colonies and cuddles, which can cop up to millions of individuals. Each ant is given a particular(a) job and it depends on the rest of the resolution for its survival expert as the community depends on this particular ant. Individuals are dual-lane into three main castes, the sterile females which include p geters, spends and former(a) gay jobs, fertile males know as drones, and the fertile female a.k.a the milksop of the colonisation.
CommunicationIn any eusocial society, the key to survival and improvement is communication. Ants communicate with apiece separate mainly through the in lead of chemicals c on the wholeed pheromones. These chemicals are collapse in most insects but are much more advanced in ants. Ants sense or smell with long and thin antennae located on the top of their head. Because they come in pairs, they provide information about direction as wellhead as intensity. Here are some communication techniques utilise by ants.
?Alarm? ? Ants use a special pheromone for defensive purposes. When attacked, ants are atrophied and do not present much of a threat so an individual ant pass on always call others. When released in low concentration, it causes the other ants to hold a state of readiness or warns others of an impending danger. A crushed or severely wounded ant nevertheless bequeath emit a high concentration of alarm pheromones that would send nearby ants into an attack frenzy. any(prenominal) species use a highly evolved ?propaganda pheromone?, which would confuse enemies and cause them to fight amongst themselves.
?Friend or Foe?? ? Pheromones are used to identify certain individuals. You can often see ants approaching each other and ?sniffing? with their mad antennae. This is done to make sure the other ant is a colony member and not an intruding ant from another(prenominal) area. Friends would go along their business or show courtesy by feeding one another. If they are foe, the ants either candidature or begin battle.
?Follow me? ? When a forager ant is move around and all of sudden finds a feed source, how does it scan down the rest of her colony to find it? Ants spend their life in contact with the ground, which makes the soil surface a great place to leave a pheromone star that the other ants can surveil. They still when touch the tip of there tum on the racecourse back to the colony which leaves a special marking pheromone As it meets up with nest twain, the excited ant go out chafe them by knocking against them and touching antennae, which causes other ants to follow the trail back to the food source. After a while, a declension of ants can be observed making their way mingled with the nest and food. As other ants come and leave, they rein personnel office the trail. When food is exhausted, no new trails are marked by returning ants and the scent slowly fades.
?How does it look doctor?? ? Pheromones can in like manner be exchanged, mixed with food, and passed. This gives other ants information about one another?s health and nutrition. Ants can overly use this to detect what task group (forging or nest aid) other ants belong to. The nance can emit a pheromone known as ? faggot substance? that causes infertility in other female ants and gives orders to raise them as workers.
Creation of a ColonyStage 1: The Founding StageDuring the summer, it is a fantastic sight to see when ants take to the air. Large winged female ants and their smaller male mates while gracefully glide in the air, looking for a partner. Following the thermal currents, they find themselves. Ants may mate in the air with the male perched on top of the cigarette or on the ground but once mated, the fairy ordain fly off leaving the male to kink up and die; his nevertheless purpose in life fulfilled. The female may mate several more times forwards she scratch lines to seek a suitable nest site. The power moldiness start the new nest completely on her own. When a good area is found, she discards her wings and digs herself a tunnel leading to small chamber with great urgency. The lonely experience volition never see sunlight again.
Stage 2: The Ergonomic StageOnce happy with the make-shift nest, she begins a process of great distress and endurance. During this time, she will neither eat nor drink and can only stay off of the wing muscles in her thorax. She will secular cranks straight aside if it?s warm which will hatch within 8-15 weeks depending on the species.
The larvae?s contract and stick adults. They are small and timid compared to the later generation that will follow. They have the most important jobs as the survival of the colony depends on this crucial point in time. The workers must fleetly begin to expand the nest, tend to the queen and broad and in the end remove the seal from the chamber entrance and forage for food. The queen must act as the leader and help influence the colonies activities but as time goes on, she will cease all other functions and become nothing but an egg set machine.
Stage 3: The Reproductive StageThe colony will exponentially increase in size and number. The ants peed will become bigger, stronger, and more aggressive. As the society grows, the complexity of job divisions amplifies as new castes are added. After a year or so when the colony is at a certain nation, the queen will lay eggs. The ants that emerge will have wings. Once again, they take flight in the mating process in hopes of creating a new colony.
Castes: Division of LaborWorker AntsThese ants make up most the colony and are infertile females. As the caste name suggests, these ants are given the responsibility of stand out the daily tasks. indoors this broad section, there are many sub-castes. Different worker ants are given different jobs like foraging, brood care, nest repair, defense and tending to the queen. An important job is nest maintenance as ants chthonicstand the significance of hygiene and disease prevention. This includes, modify and transporting dead ants out of the nest. In certain cases, workers may lay eggs, but are normally used as food. However, they may develop into male ants which would only be allowed to happen when the queen has died. Although the colony is doomed, at least the male may carry-on the genes and inseminate a virgin ant elsewhere.
SoldiersSome colonies have specialized soldier ants. They are the largest of the castes. They have enlarged jaws that snap shut at great speeds. Huge muscles allow them move around hurrying and inflict more harm on enemies. Worker ants are usually first at the scene but soldiers follow close behind when more assistance is needed.
Queen Antsqueen must first go through great hardship to start up a colony. During this time, she does not eat or drink. Queens also never see the sun after they have settled. After her first brood has grown into adults, she ceases all other responsibilities and her existence will solely be for the purpose of egg laying. Queens are larger than workers and can be today recognizable by the difference in size of the thorax. The abdomen is also engrossed to accommodate the advanced egg producing organs. They also produce a special pheromone known as ?queen substance? that causes infertility in worker ants. After the population has reached a certain high, the queen must then produce fertile females and males in hopes that another colony can be created nearby. Queens are the longest living ants in the colony.
manful AntsMale ants have a very minor role in the societies.
They are winged and only have one role in life ? to inseminate a virgin queen during the mating flight. Once they have performed this task, they will live for only 1 to 2 more days before they curl up and die. Sometimes referred to as ?drones?, male ants are the smallest and live the shortest amount of time.
Other Cool Stuff?Sneaky Take-Over? Some newly mated queens of the species Formica Sanguinea create colonies in a different way. The new queens will force her way through another colonies nest with stealth and specialization and create a sub-cell where she defends and steals a couple of broods. Once the broods hatch, under the control of the intruder, they are able to infiltrate the colony collectable to their similar appearance. They then kill the original queen which allows the other to take her place on the throne.
?Biological Storage outline? In desert-dwelling ants, they have very unique caste. The ants in this group serve as living storage! When food has been collected, it is only when fed to certain ants. Eventually, their stomach expands to a massive size. When cut-and-dry workers get hungry, the balloon ants regurgitate some of the stored food into the workers mouth.
?I Am Your Master? Several ant species, such as those of the Polyergus genus, capture the young of other ants to raise and wait as servants. Some species of ?slavemakers? cannot survive without their captives to feed them and care for their young.
?bushwhacker Ants? A species of ants farm! As crazy as that sounds, leaf-cutting ants grow their food in huge underground nests. Workers cut bits of leaves and carry them to the chamber, where they compost leaves and droppings. A special fungus grows on the compost. The ants are so sensitive that they know how the fungus reacts to different plant material. If they find that one leaf is poisonous, they will no longer collect it. in all life stages eat only this fungus.
?You Won?t the like Me When I am Angry? The bulldog has nothing on the Australian bulldog ant. These critters aggressively chase down course. It?s not surprising that they always catch what they want as they can jump nearly a foot, have irrational inch long jaws and ¼ inch-long poisonous stinger.
?Path of Destruction? If you are an insect, you might want to stay away from the African number one wood ant. These army ants travel in huge columns for long distances and periods of time, capturing every(prenominal) insect in their way. They destroy and even eat small animals. Driver ants love invading other colonies. They are known to search every tunnel and chamber, devouring the king and queen of termites/ants as well as many thousands of workers. A driver-ant break can wipe out an entire colony.
?Symbiotic honor? A species of caterpillars are herded by ants! Myrmecohilious caterpillars are moved to angel feeding areas in the daytime and brought back inside the ant?s nest at night for safe keeping. The caterpillars have a gland which secretes honeydew, a sweet sugar high in energy which ants love. Aphids also secret this liquid and will produce it when asked politely through a gentle rap by an ants antennae. The ants in turn will keep predators away and move the aphid around to better feeding locations.
?Feels like burning at the stake? Fire ants use there jaws to lock on to their prey or enemy and use their abdomen to sting. The sensation caused by the venom is compared to being lit on fire. This is where the Fire ant gets its? name.
