Did you KNow that one of the Dangerous Insect in the World?

Insects (from Latin insectum, a calque of Greek ἔντομον [éntomon], "cut into sections") are a class within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae.

1 . Scorpion

Like spiders, scorpions are arachnids. There are close to 2,000 species of scorpions in the world with at lease 40 different species living in North America.

Like the spider, they have eight legs but they also have a pair of crablike pincer in front and a stinger at the tip of its tail. It has two main body parts, the Cephalothorax which comprises the bulk of its body, and the Metasoma which is its tail.

The Scorpion has eyes on the top of its head as well as two to five pairs of eyes along the front corners of its head. Its exoskeleton is thick and it can move quickly on its four pairs of legs. The claws are worrisome but it's the stinger attached to its tail that causes most the trouble.

Scorpions prey on bugs, lizards, and mice. It is rare for a human to get stung, but when they do the symptoms are severe. The sting burns and as the venom makes its way through the body, the victim will start to drool and shake. It is often accompanied with stomach cramps. Confusion reigns. They don't understand what's happening or why.

Children under the age of five are at the greatest risk when stung by a scorpion. Adults will get sick, but unless they were stung several times, they rarely die.

2. Puss Caterpillar 

  

Megalopyge opercularis is often called the southern flannel moth or pussy moth. It's when they are in caterpillar form that they are the most dangerous. The body is covered with long, red-brown hairs. It looks soft, but when frightened, its hair rises. Beneath the hair are needle-like spines connected to a poison-filled gland. The poison is injected into anything it touches.

The poison causes a burning pain, swelling and numbness to the sight of entry, an in severe cases it can cause high fever, vomiting and paralysis.

The M. opercularis are fairly common throughout the southern United States, Mexico and parts of Central America. They can be found on oak, elm, birch, citrus trees and many other common trees. It can also be found in the garden feasting on plants and flowers such as the ivy and the rose bush.

While the Puss Caterpillar rarely causes death, crossing swords with one can and will be a painful experience.

3. Assassin bug (Kissing Bug) 

The Triatoma protracta often bite their victims around the mouth and nose while they are sleeping, hence the name, Kissing Bug. Another fairly common name is the Assassin Bug. There are several species of Kissing Bug, and some have a painless bite, while others are said to be the most painful bite of any insect.

The real danger comes after the bite. The Kissing Bug spreads Chagas' disease. Some victims show signs immediately. They suffer rash, fevers and vomiting. Often the skin near the eyes will swell, but only a few of these victims dies.

Other victims are asymptomatic for years. The disease will lurk in their blood only to surface twenty to thirty years after the initial bite. At that point it is difficult to determine the cause of the heart and digestive problems the victim is suffering and is often misdiagnosed.

They are fairly common in the Southwestern United States.

4. Mosquito 

Mosquitoes are a common insect found throughout the world. Most people consider them pests, but they are a vector agent for some of the world's most deadly diseases.

The mosquito is a small flying insect with a forward facing needle-like projection called a proboscis. The proboscis is used to suck the blood from warm blood vertibrates, including humans. They are carries of many diseases, including West Nile virus, yellow feaver, and encephalitis. Some also carry the parasite responsible for malaria.

Every year 300 million people across Africa, South America, and Asia are infected with malaria. The malaria parasite destroys blood cell and clogs the flow of blood. Most deaths occur in Africa where a child dies from malaria every 30 seconds.
