Animal Behavior


Look for something to eat:
Ants are mostly omnivorous. That is, they are eating everything from other insects, seeds, oils, and breadcrumbs. Ants will be the fastest clustered if there are foods such as chicken or fish fry. Foods that have a certain smell will usually be faster than that is not surrounded by ants like syrup or sugar water. There are ants that climbed to the top of the food being transported by another friend. Ants are located above the food is in charge of maintaining the food they bring from possible threats coming from above. Tropical leaf-cutter ants use their sharp jaws to cut the leaves and make it into a kind of porridge (pulp). The pulp is then used as a medium for mushroom cultivation are becoming their food.

Self defense:
At the front of the ant's head also has a pair of jaw or mandible used to carry food, manipulate objects, construct nests, and for defense. Some species of ants also have a sting that is connected with some sort of poisonous glands to immobilize prey and protect the nest. Ant species such as Formica yessensis has a formic acid-producing gland that can be sprayed into the enemy's defenses.

Sleep habits:
Most people think ants never sleep. When in fact, the worker ants can sleep as many as 253 times a day. How can? This is because they only spent 1.1 minutes on one bed.

Habitat of Ants

Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.

Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist mostly of sterile, wingless females forming castes of "workers", "soldiers", or other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens". The colonies are described as superorganisms because the ants appear to operate as a unified entity, collectively working together to support the colony.

Ants have colonised almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in most ecosystems and may form 15–25% of the terrestrial animal biomass. Their success in so many environments has been attributed to their social organisation and their ability to modify habitats, tap resources, and defend themselves. Their long co-evolution with other species has led to mimetic, commensal, parasitic, and mutualistic relationships.

Though ants build complicated nests mostly they are nomads. They may build subterranean nest or build nest on trees. Nests can be seen in the ground, under logs or stones, inside logs, acorns and in hollow stems. Some ants avoid nest sites that have dead ants, as this indicates pest presence or the presence of disease. Ants rapidly vacate a nest, if they sense danger. Ants also build nests in buildings, walls, electric appliances and windows.

Scrum Description


Link to Scrum.org: https://www.scrum.org/

What is Scrum?

Scrum is an iterative and incremental agile software development framework for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project.
A key principle of scrum is its recognition that during production processes, the customers can change their minds about what they want and need (often called requirements volatility), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. As such, scrum adopts an empirical approach—accepting that the problem cannot be fully understood or defined, focusing instead on maximizing the team's ability to deliver quickly, to respond to emerging requirements and to adapt to evolving technologies and changes in market conditions.

There are three core roles[14] in the scrum framework. These core roles are those committed to the project in the scrum process—they are the ones producing the product (objective of the project). They represent the scrum team. Although other roles may be encountered in real projects, scrum does not define any team roles other than those described below.[15]

Product owner

The product owner represents the stakeholders and is the voice of the customer, who is accountable for ensuring that the team delivers value to the business. The product owner writes (or has the team write) customer-centric items (typically user stories), ranks and prioritizes them, and adds them to the product backlog. Scrum teams should have one product owner, this role should not be combined with that of the scrum master. The product owner should be on the business side of the project, and should never interfere or interact with team members on the technical aspects of the development task.[16][better source needed] This role is equivalent to the customer representative role in some other agile frameworks.

Role in requirements communication

Communication is a main function of the product owner. The ability to convey priorities and empathize with team members and stakeholders is vital to steer the project in the right direction. Product owners bridge the communication gap between the team and its stakeholders. they serve as a proxy stakeholder to the development team and as a project team representative to the overall stakeholder community.
As the face of the team to the stakeholders, the following are some of the communication tasks of the product owner to the stakeholders:[citation needed]
  • demonstrates the solution to key stakeholders who were not present at a sprint review;
  • defines and announces releases;
  • communicates team status;
  • organizes milestone reviews;
  • educates stakeholders in the development process;
  • negotiates priorities, scope, funding, and schedule;
  • ensures that the product backlog is visible, transparent, and clear.
Empathy is a key attribute for a product owner to have—the ability to put one’s self in another’s shoes. A product owner converses with different stakeholders in the project, who have a variety of backgrounds, job roles, and objectives. A product owner must be able to see from these different points of view. To be effective, it is wise for a product owner to know the level of detail the audience needs. The development team needs thorough feedback and specifications so they can build a product up to expectation, while an executive sponsor may just need summaries of progress. Providing more information than necessary may lose stakeholder interest and waste time. There is also significant evidence that face-to-face communication around a shared sketching environment is the most effective way to communicate information instead of documentation.[citation needed] A direct means of communication is the most preferred by seasoned agile product owners.
A product owner’s ability to communicate effectively is also enhanced by being skilled in techniques that identify stakeholder needs, negotiate priorities between stakeholder interests, and collaborate with developers to ensure effective implementation of requirements.

Development team

The development team is responsible for delivering potentially shippable increments (PSIs) of product at the end of each sprint (the sprint goal). A team is made up of 3–9 individuals who do the actual work (analyse, design, develop, test, technical communication, document, etc.). Development teams are cross-functional, with all of the skills as a team necessary to create a product increment. The development team in scrum is self-organizing, even though there may be some level of interface with project management offices (PMOs).

Scrum master

Scrum is facilitated by a scrum master, who is accountable for removing impediments to the ability of the team to deliver the product goals and deliverables. The scrum master is not a traditional team lead or project manager, but acts as a buffer between the team and any distracting influences. The scrum master ensures that the scrum process is used as intended. The scrum master helps ensure the team follows the agreed scrum processes, often facilitates key sessions, and encourages the team to improve. The role has also been referred to as a team facilitatoror servant-leader to reinforce these dual perspectives.
The core responsibilities of a scrum master include (but are not limited to):
  • Helping the product owner maintain the product backlog in a way that ensures the needed work is well understood so the team can continually make forward progress
  • Helping the team to determine the definition of done for the product, with input from key stakeholders
  • Coaching the team, within the scrum principles, in order to deliver high-quality features for its product
  • Promoting self-organization within the team
  • Helping the scrum team to avoid or remove impediments to its progress, whether internal or external to the team
  • Facilitating team events to ensure regular progress
  • Educating key stakeholders in the product on scrum principles
One of the ways the scrum master role differs from a project manager is that the latter may have people management responsibilities and the scrum master does not. Scrum does not formally recognise the role of project manager, as traditional command and control tendencies would cause difficulties.

 How the team use Scrum?

The Ant Team used Scrum for their project, start from Scrum planning with using Scrum board to determine the task of every people to help the Scrum task finish on time. After that we do the retrospective moment to evaluate the Scrum task by giving the opinion of what is like, what we don't like, who is the best, and what to improve.



Reproduction of Ant

Ants undergo complete metamorphosis—from egg, to larva, to pupa, to adult. Each ant colony begins with, and centers on, the queen, whose sole purpose is to reproduce. Although the queen may copulate with several males during her brief mating period, she never mates again. She stores sperm in an internal pouch, the spermatheca, near the tip of her abdomen, where sperm remain immobile until she opens a valve that allows them to enter her reproductive tract to fertilize the eggs. A queen carpenter ant can lay 30 eggs a year after her colony is established for over a year and only 10-15 the first year. But fire ant queens can lay up to 1500 eggs a day.

The queen controls the sex of her offspring. Fertilized eggs produce females (either wingless workers seldom capable of reproduction, or reproductive virgin queens). Unfertilized eggs develop into winged males who do no work, and exist solely to fertilize a virgin queen. The queen produces myriads of workers by secreting a chemical that retards wing growth and ovary development in the female larvae. Virgin queens are produced only when there are sufficient workers to allow for the expansion of the colony.

Queens live long lives in comparison with their workers and are prolific breeders. A queen of Lasius niger, a common ant found in Europe, lived for 29 years in captivity, while the queen of the urban Pharaoh's ant, Monomorium pharaonis, lives for only three months. The queen of the leafcutter ant from South America produces 150 million workers during her 14-year life span.

The first phase of colony development is the founding stage, beginning with mating, when winged males and virgin queens leave the nest in massive swarms called nuptial flights, searching out a mate from another colony. In colonies with large populations, like that of the fire ant Solenopsis, hundreds of thousands of young queens take to the air in less than an hour, but only one or two individuals will survive long enough to reproduce. Most are taken by predators such as birds, frogs, beetles, centipedes, spiders, or by defensive workers of other ant colonies. A similar fate awaits the male ants, none of which survive after mating.

After mating, queen ants and male ants lose their wings. The queen scurries off in search of a site to start her new nest. If she survives, she digs a nest, lays eggs, and single-handedly raises her first brood that consists entirely of workers. In leafcutter ants, adults emerge 40–60 days after the eggs are laid. The young daughter ants feed, clean, and groom the queen ant. The workers enlarge the nest, excavate elaborate tunnel systems, and transport new eggs into special hatching chambers. Hatchling larvae are fed and cleaned, and pupated larvae in cocoons are protected until the young adults emerge to become workers themselves.

The colony now enters the ergonomic stage, a time entirely devoted to work and expansion. It may take a single season or five years before the colony is large enough to enter the reproductive stage, when the queen ant begins to produce virgin queens and males that leave the nest at mating time to begin the entire cycle anew.

In some species, a new queen founds a new colony alone; in others species, several queens do so together. Sometimes, groups of workers swarm from the nest with a young queen to help her establish her nest. In colonies with several already fertile queens, such as in the Costa Rican army ant Eciton burchelli, entire groups break away with their individual queens to establish individual colonies. In single queen colonies, such as those of the fire ant, the death of the queen means the death of the colony, as she leaves no successors. Colonies with multiple queens survive and thrive.

The family Formicidae belongs to the order Hymenoptera, which also includessawfliesbees, and wasps. Ants evolved from a lineage within the aculeate wasps, and a 2013 study suggests that they are a sister group of the Apoidea.[17] In 1966, E. O. Wilson and his colleagues identified the fossil remains of an ant (Sphecomyrma) that lived in the Cretaceous period. The specimen, trapped in amber dating back to around 92 million years ago, has features found in some wasps, but not found in modern ants.[18] Sphecomyrma possibly was a ground forager, while Haidomyrmexand Haidomyrmodes, related genera in subfamily Sphecomyrminae, are reconstructed as active arboreal predators.[19] After the rise of flowering plantsabout 100 million years ago they diversified and assumed ecological dominance around 60 million years ago.[20][21][22][23] Some groups, such as the Leptanillinaeand Martialinae, are suggested to have diversified from early primitive ants that were likely to have been predators underneath the surface of the soil.[2][24]
During the Cretaceous period, a few species of primitive ants ranged widely on the Laurasian supercontinent (the Northern Hemisphere). They were scarce in comparison to the populations of other insects, representing only about 1% of the entire insect population. Ants became dominant after adaptive radiation at the beginning of the Paleogene period. By the Oligocene and Miocene, ants had come to represent 20–40% of all insects found in major fossil deposits. Of the species that lived in the Eocene epoch, around one in 10 genera survive to the present. Genera surviving today comprise 56% of the genera in Baltic amber fossils (early Oligocene), and 92% of the genera in Dominican amber fossils (apparently early Miocene).[20][25]
Termites, although sometimes called 'white ants', are not ants. They belong to the sub-order Isoptera within the order Blattodea. Termites are more closely related to cockroaches and mantids. Termites are eusocial, but differ greatly in the genetics of reproduction. The similarity of their social structure to that of ants is attributed to convergent evolution.[26] Velvet ants look like large ants, but are wingless female wasps.[27][28]

Animal Cartoon 



A Bug's Life is a 1998 American 3D computer-animated comedy adventure film produced by Pixar Animation Studios and distributed by Walt Disney Pictures. Directed by John Lasseter and co-directed by Andrew Stanton, the film involves a misfit ant, Flik, that is looking for "tough warriors" to save his colony from greedy grasshoppers, only to recruit a group of bugs that turn out to be an inept circus troupe. Randy Newman composed the music for the film, which stars the voices of Dave Foley, Kevin Spacey, Julia Louis-Dreyfus, Hayden Panettiere, Phyllis Diller, Richard Kind, David Hyde Pierce, Joe Ranft, Denis Leary, John Ratzenberger, Jonathan Harris, Madeline Kahn, Bonnie Hunt, Mike McShane and Brad Garrett.

The film is inspired by Aesop's fable The Ant and the Grasshopper.[3] Production began shortly after the release of Toy Story in 1995. The screenplay was penned by Stanton and comedy writers Donald McEnery and Bob Shaw. The ants in the film were redesigned to be more appealing, and Pixar's animation unit employed new technical innovations in computer animation. During production, the filmmakers became embroiled in a public feud with DreamWorks Animation due to their similar film, Antz.


Diet Information of Ants

Diet Information


Most ants are generalist predators, scavengers, and indirect herbivores, but a few have evolved specialised ways of obtaining nutrition. It is believed that many ant species that engage in indirect herbivory rely on specialized symbiosis with their gut microbes to upgrade the nutritional value of the food they collect and allow them to survive in nitrogen poor regions, such as rainforrest canopies. Leafcutter ants (Atta and Acromyrmex) feed exclusively on a fungus that grows only within their colonies. They continually collect leaves which are taken to the colony, cut into tiny pieces and placed in fungal gardens. Workers specialise in related tasks according to their sizes.

The largest ants cut stalks, smaller workers chew the leaves and the smallest tend the fungus. Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is found to be toxic to the fungus, the colony will no longer collect it. The ants feed on structures produced by the fungi called gongylidia. Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi.

They are common pests in agricultural areas where they can quickly devour crops, that's why Ant eats almost every hour.Ants feed on a large range of foods, from engine oil at the side of a road, to other ant species. Most ant species are omnivorous and eat seeds, nectar, and other invertebrates.

The amount an ant will eat will vary from species to species, but the average ant consumes approximately 1-2 miligrams of food per day - About 20-35% of their body weight. This is not the same as the amount of food that they will harvest, or bring back to the nest. An ant will make an average of 30 foraging trips each day, and often times they will be carrying 5 to 50 times their body weight. Using 5 times their body weight as our average load, it is not unreasonable for a single ant to bring back 750mg (almost 1 gram) to the colony each day.

How ant communicate each other

Ants communicate with each other and with other animals using pheromones, sounds, and touch. The use of pheromones as chemical signals is more developed in ants, such as the red harvester ant, than in other hymenopteran groups. Like other insects, ants perceive smells with their long, thin, and mobile antennae. The paired antennae provide information about the direction and intensity of scents. Since most ants live on the ground, they use the soil surface to leave pheromone trails that may be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony; this trail is followed by other ants, these ants then reinforce the trail when they head back with food to the colony. When the food source is exhausted, no new trails are marked by returning ants and the scent slowly dissipates. This behaviour helps ants deal with changes in their environment. For instance, when an established path to a food source is blocked by an obstacle, the foragers leave the path to explore new routes. If an ant is successful, it leaves a new trail marking the shortest route on its return. Successful trails are followed by more ants, reinforcing better routes and gradually identifying the best path.

Ants use pheromones for more than just making trails. A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away. Several ant species even use "propaganda pheromones" to confuse enemy ants and make them fight among themselves.]Pheromones are produced by a wide range of structures including Dufour's glands, poison glands and glands on the hindgut, pygidium, rectum, sternum, and hind tibia. Pheromones also are exchanged, mixed with food, and passed by trophallaxis, transferring information within the colony. This allows other ants to detect what task group (e.g., foraging or nest maintenance) other colony members belong to. In ant species with queen castes, when the dominant queen stops producing a specific pheromone, workers begin to raise new queens in the colony.
Some ants produce sounds by stridulation, using the gaster segments and their mandibles. Sounds may be used to communicate with colony members or with other species.

Ant Anatomy and Biology

Size information
Ants, like all insects, have jointed legs, three body parts (the head, thorax and abdomen), a pair of antennae, and a hard exoskeleton. The exoskeleton is made up of a material that is very similar to our fingernails. Ants range in color from yellow to brown to red to black.

Some ants have a stinger and some can even inject poisonous acid from the stinger (the stinger is at the tip of the abdomen, the rear body segment). Ants can also bite using their jaws (mandibles). Ants range in size from about 0.08 inch (2 mm) to up to about 1 inch (25 mm) long.



Unique Physical
Abdomen - The abdomen is the segmented tail area of an ant. It contains the heart,Malpighian tubules, reproductive organs, and most of the digestive system (foregut, hindgut and rectum). It is protected by an exoskeleton.

Antennae - Ants have two jointed antennae. They are sensory appendages attached to the head.

Compound eye - Ants have two compound eyes. These eyes are made up of many hexagonal lens/corneas which focus light from each part of the insect's field of view onto a rhabdome (the equivalent of our retina).


Head - The head of an ant (or any insect) is the location of its brain, two compound eyes, its proboscis, pharynx (the start of the digestive system), the point of attachment of its two antennae, etc.

Jointed Leg - Ants, like all insects, have six jointed legs.

Mandibles - Mandibles are the jaws of the ant. The mandibles bite off food and tear it into small, easily digestible pieces.

Thorax - The thorax is the chest area of an insect (including ants). The thorax is divided into three segments; on each segment is a pair of legs. The thorax contains the muscles that make the legs move.


How Ant Breathe
Ants, like all insects, don’t have lungs, breathing through tiny holes in their sides – spiracles – one pair per segment. These lead into a network of tiny tubes – tracheae – permeating their entire body, getting narrower and narrower, supplying air (and hence oxygen), right to the tissues that use it, rather than using blood to transport it like us. Though they can open and close their spiracles, they have little ability to pump air in and out, which happens just through general movement. It’s this inability that stops insects getting as big as us, with our ultra-efficient lungs and blood.


Life Cycles
The average lifespan of a worker ant is about 6 months
the average lifespan of a queen is 3 years....

The life span of the ant varies from caste to caste, and species to species. The workers of some species live only for a few weeks, where other ants may live for a few years....... The queen of the tiny 'Pharaoh ant, may live for only three months, but the queen of black garden ant can live for up to 15 years or so!!!! The record for ant longevity is held by a black garden ant queeen who, in a German laboratory nest, lived for 29 years
