Insecta refers to insects belonging to the Insecta class in the Hemiptera. Entomologists have classified them as true insects. They have four legs, hair, and gills. You may already know their looks, but did your know that they have other distinguishing characteristics?
Insects are invertebrates
Invertebrates refer to bugs as having both living and dead parts. Insects have segmented body parts and exoskeletons made from chitin. The body is divided into three main units: the head and thorax. These body segments are used by insects to extract nutrients from food. Insects use catabolic reactions to digest their food. These reactions break down complex macromolecules and create simple sugars and amino acid.
They have four legs
It's interesting to see that not all insects have the same number of legs as others. For example, the locusts have only four legs while butterflies have six. For jumping, insects use their front pair.
They have gills
Most people are aware of the fact that some insects have "gills". Gills are a way for insects to breathe. They also allow them to see the surrounding environment. Some species have compound eyes that combine hundreds of visual elements. While most insects have eyes composed of multiple visual units, others have complex eyes. For example, caterpillars have 12 sets eyes and 30,000 ommatidia.
They have hair
If you are into bugs, then you need to be aware of the fact that they have hair. Insects have the highest diversity of animals. This makes them a fascinating group to study. They play an important part in our environment, economy, and are fascinating to both humans as well as non-entomologists. Here are some interesting facts about insects, including what they eat and how they jump.
They also produce methane
Methane is a greenhouse-gas that is released by insects such as termites. These insects produce methane from their stomachs and are responsible for approximately 5 percent of the global methane emissions. While methane is naturally occurring in the atmosphere, human activities account for 320 million tons of methane each year. Fossil fuel industries (including the production of natural gas) are the largest sources of methane.
They are ommatidia
Insects are equipped with compound eyes, which consist of seven to 11 individual visual units. They can be used to perform a variety different tasks. Some insects have more or less ommatidia. For example, the wingless silverfish has fewer than a hundred, while the dragonfly has about 30,000. Interestingly, male insects have more ommatidia than females, making them more easily distinguishable.
They have some of the most bizarre body parts
Insects are one of the most diverse groups of organisms in the world. Insects not only contribute to many countries' economies, but are also fascinating for humans and other non-entomologists. Did you know that grasshoppers have ears on their belly? In addition to this, its hind legs have special organs for jumping. The grasshopper can leap up to twice the length of an NBA court. They are also the first animals to produce sound, thanks to their incredible body parts.

What is the most secretive location in the entire world?
You might be surprised at the answer. You might be uncomfortable with the truth of it, as it may challenge your perception of reality. However, there's a reason for this place to exist. It's not what we would expect.
It was called the City of God by ancient Greeks. In the Bible, it was known as the City of Destruction.
It is called Kashi (Kashmir in India). In Russia, it's called Novgorod.
However, in America it is called The Town that Disappeared.
One small New York State town with just 1,200 people vanished. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
The little village vanished, with no trace of its existence. Some believe the earth swallowed them up. Some claim it was destroyed by a meteorite impact. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
The people of this once-thriving community, however, are positive that the town won't disappear forever. They just moved to another city.
A website is available to track the disappearance and recovery of Zugspitz, which was lost in the Great Depression.
The question is, where did this place go? It's in Switzerland.
Zugspitze lies on the border between Austria and Germany. The lake Lake Zugspitze is just beyond the mountain's summit.
It has always fascinated my that so many towns have disappeared but others still exist. What is the difference between some towns that disappear and others that survive? I decided to investigate.
I wanted to know more about the mysterious disappearing towns. Is it possible for a place to vanish? How can a town disappear from existence?
There are many theories to explain the phenomenon of disappearing towns. One theory holds that a town disappears if all its buildings are demolished. Another theory holds that the town simply relocates to another location. A third theory claims that the town never existed at all.
Although theories may be a bit speculative, it is a fact that numerous towns have been destroyed by the elements. This video examines the history and current status of these places.
Ever wonder how much trash gets produced each day around the world?
According to the United Nations the average person creates more than 2.5 lbs of waste daily. That adds up over 25 billion kilos of garbage every year.
Most of this trash ends up in landfill dumps or incinerators.But what happens when those dumpsters get full? It goes to the United States, where most of it is exported. It is then shipped out and dumped in other countries. This pollutes the ecosystems. But now we know, thanks to one man. His name is Mike Sexton. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He then gives us a report on what happens next.
Sexton claims he is very satisfied with his job. CNN spoke with Sexton that they have a lot fun. "We'll be following these big rigs through town. "Sexton began following truck drivers almost 20 years ago.
"It's all I felt," he stated.
Sexton loved the story about the driver who pulled over at an abandoned gas station close to Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He drove down the street and saw this building. He stopped and pulled up, then he went inside. "There were two huge roll-off containers there filled with stuff. The guy took everything out and started filling up the truck again. "Then he took out everything and began to fill up the truck. There were lots of old tires, rags furniture, mattresses, mattresses, cans, cans, and other items. "It was just a total mess. But it was cleaned out before he came. There was no trash."
So why did this happen? The answer is that this location was once part of a recycling facility. People who knew about it would drive to this location to recycle their garbage. Sexton said that people would bring their household items to the building and then leave empty containers behind.
Now, because of the way the law works, once a container reaches its destination, it cannot be opened.So no matter how often someone takes something out of it, the thing will never be emptied.Every time the truck comes by, it has to start over again. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. The truck eventually stops running and the owner decides that it is time to get rid of the vehicle.
Trash isn’t the only problem we face on the planet.
The majority of these particles are made of small pieces of plastic. Some of these plastics end up in rivers or oceans.
Experts say if nothing changes, we could soon face a global food shortage. Experts warn, "If you keep going like you're going," we could soon face a global food shortage. But most people don't seem to be worried, even though scientists are unanimous in warning us that the world is heading towards disaster.
Is there a Hollywood blacklist.
There is a Hollywood blacklist.
However, the list isn’t public. We don't know the names. Here's why this matters.
The secretive nature of the information is due to the fact that actors and directors on blacklist won't be in a position to find work. This would result in studios losing money as the actors and directors would have to go out on their own. Which means they'd cut back on spending money on movies. The blacklisted filmmakers would have fewer chances. Which would lead them to go bankrupt.
This could lead to more victims.
If someone attempts to make an Oscar-winning movie, they may be asked to sign a contract stating that they will not speak out against their employers. The same goes for any director or producer who wants to get nominated for an award.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Or how directors threaten to walk away from projects that don't fit their vision.
This is why Hollywood has a blacklist. If you make negative comments about your employer, it's likely that you will be unemployed. And that's not good for anyone.
Many people have been wrongly accused. It's been a struggle to get their names cleared.
We need to stop this kind of thing before it starts happening again. Everyone should have the right to speak freely.
We need to get rid of Hollywood's blacklist.

Hollywood scandals that shocked all of the world
There is nothing more shocking than witnessing someone get famous for the wrong reasons. It's even more frightening to see them fall from grace.
It is amazing to see how an industry handles its mistakes. We have all heard of celebrities who overdosed on drugs and alcohol. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. That's where we found ourselves last week.
Heath Ledger lost his long and successful career. He took too many prescription pills and died shortly after.
His family and close friends had difficulty accepting his death. The media took to him publically.
Heath was once thought to be one the greatest actors of all time. Two Academy Awards nominations went to Heath for his performance on Brokeback Mountain.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
Hollywood loved Heath, but he became too big for his britches. He started taking drugs and drinking heavily. He was eventually able to get clean and went to rehab.
Now that he was sober, it was time to make amends. He made a documentary called "Room 237," that chronicled the making and release of The Shining. It was supposed that it would be released this year but it won't make its debut in theaters until next.
Heath was unsuccessful in his attempts to get back into Hollywood. He was actually arrested twice for drug charges.
Although we don't think Heath should be allowed to return to the showbiz, But it would have been nice to get some help before things spiralled out of control.
We hope Heath's story will serve as a warning to others who may think they can still have everything.
