Like most social insects, ants need to communicate with each other. If you watch ants on a trail, you will notice that they often touch each other with their antennae (long feelers on the head) when they meet. All ants can produce pheromones, which are scent chemicals used for communication and to make trails.
The young scientists learn how ants work as a community and are friendly to each other, communicating using chirping sounds called stridulation. This is a sound made by rubbing two parts of their abdomen together. They use this to communicate to others where the best leaves are on the plant and if they are in trouble.
The ants have antennae in place of nose to smell. When they meet with other ants, they strike their antennae in them to communicate with each other. By this, they get signals related to availability of food or sometimes exchange food.
It’s how nutrients are passed from foraging ants to nurse ants, and from nurses to the larvae in a colony. Other research has suggested that ants also use trophallaxis to spread the colony’s odor, helping them identify their own nest mates.
“The main advantage is to allow your sister workers to lay male eggs, rather than the queen, who typically stops worker reproduction by egg eating, attacking reproducing workers, and by laying many of her own eggs. By eliminating the queen, a matricidal worker allows other workers and herself to lay male eggs.”
She lays dozens or even millions of eggs which then hatch into new workers. When the queen ant dies, the colony dies, according to the “Smithsonian Zoogoer.” The death of the colony will not be immediate, but will slowly die off over time as no new members will be added.
Once it has bitten and latched on, the ant will typically sting repeatedly (on average 7-8 times) in a circular pattern around the bite site by pivoting its abdomen. Initially, the venom causes a burning sensation, swelling, and pain at the sting site.
Necrophoresis is a behavior found in social insects – such as ants, bees, wasps, and termites – in which they carry the dead bodies of members of their colony from the nest or hive area. This acts as a sanitary measure to prevent disease or infection from spreading throughout the colony.
Workers serve as undertakers in mature ant colonies, removing dead individuals and carrying them to a trash pile either far away or in a specialized chamber of the nest. In certain species, they will bury the corpse instead. (Watch ants carry their wounded off the battlefield in findings from a separate study.) …
Ants don’t scream. Ants are tidy creatures. And they communicate by chemical scents. When an ant dies its scent changes because the corpse releases something called oleic acid.
Growing up all alone sounds a bit sad, but for some ants it can get much worse than that. Parts of their brain end up stunted, and their behavior turns them into social pariahs for life.
Ants hate cayenne pepper. Black pepper will work just as well too. Locate the source of the ant infestation problem, sprinkle some pepper around that area and if possible, create a wall that will stop the ants from accessing your household.
Ants don’t scream. Ants can’t scream. What you may be hearing is the timber on the deck stretching as it’s absorbing the water, or maybe it’s just the sound of water running through the pipes.
Yes ants fart. Yes, tremendously. Yes. An ant’s arsehole is the smallest orifice in any known creature and the sound of an ant farting has been recorded as the lowest decibel-level achievable in nature.
They (at least seemingly) cannot sense death directly, though; it’s easy to find situations where you can observe many ants wandering aimlessly past recently-deceased insect carcasses without noticing… but when they finally stumble upon the carcass they become very excited and agitated because it’s such a good …
As far as entomologists are concerned, insects do not have pain receptors the way vertebrates do. They don’t feel ‘pain,’ but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don’t have emotions.
While ants use a fluid somewhat analogous to blood for nourishing their tissues, it is not contained within vessels as it is in vertebrates. While they lack a proper heart, they do have a pumping organ called a dorsal aorta that pumps blood towards the head, achieving a small current.
Each ant’s brain is simple, containing about 250,000 neurones, compared with a human’s billions. Yet a colony of ants has a collective brain as large as many mammals’. Some have speculated that a whole colony could have feelings.
According to the World Health Organization, cockroaches can carry harmful diseases such as dysentery, cholera, leprosy, and more. Therefore, if you spot one of these brown creepy crawlers in your home, it’s best to kill it right away.
Finding roaches is not a sign that your house is dirty. Even if you clean regularly and maintain a tidy home, cockroaches can usually find food and water without much trouble. This allows them to thrive in many environments.
“One signals immediate danger, and one signals the potential for disease or contamination.” If those two emotions form a Venn diagram, cockroaches would scurry inside the area of overlap. “Cockroaches are oily and greasy, which is a real signal for disgust,” Lockwood says.
Cockroaches have extremely strong and flexible exoskeletons, which make them almost impossible to squish, withstand the hardest stomp or the toughest newspaper. They can also flatten themselves to fit into tight spaces and crevices, making for an easy getaway.
As it turns out, cockroaches can withstand a huge amount of radiation – which is why many survived the 1945 blasts. However, they’re not indestructible. In the tests conducted by Mythbusters, some German cockroaches were exposed to varying levels of radiation to see how much it took to finish them off. It was a lot.
Summary: In its ability to learn, the cockroach is a moron in the morning and a genius in the evening. Dramatic daily variations in the cockroach’s learning ability are reported in a new study. The few studies that have been done with mammals suggest their ability to learn also varies with the time of day.
Impact: Cockroaches crawl through dirty areas and then walk around our homes tracking in lots of bacteria and germs. They can contaminate food by shedding their skins. Their cast off skin and waste byproducts are allergens that can trigger allergic reactions, asthma and other illnesses, especially in children.
