For many of us are crawling insects, but not afraid of anything, that little ugly and noise pollution. But insects are animals that play an important role in our world and there are literally millions of insects spieces. They are a subgroup of the group known as arthropods. Arthropods are animals with exoskeletons and segmented bodies. There are a number of properties that easily recognizable and clearly distinguishable from other animals that are mistaken for insects when you can not know, make them better. One of these features is to have three different body segments. These three areas are the head, chest and abdomen. The head is explicit, the thorax is connected to the head, like a human torso. And the abdomen is attached to the chest, like the back of the insect.
The next feature of insects is that they have six legs together. There are three pairs of legs at all and fix all the thorax. If you attached a small creature on the floor with your feet in the stomach, so it’s not a bug. Another feature is the presence of antennas on top of the insect. It should be noted that this is typical of insects, but a small number of insects have antennae. More guinea pig is the presence of wings. There are some types of insects that do not fly, but the wings must be present at some point in their development. The last feature is a rigid exoskeleton. It is very easy to identify the insects in relation to these characteristics. The problem comes in different stages of the life cycle of insects, if they can not all these properties. For example, the crawler without wings or antennae, but later, when the butterflies. It is therefore important for both adults and Development to examine the samples. Read the rest of this entry »
Many people think that the error, such as insects, but the fact of the matter is that every little thing, creepy creepy, and may be a mistake. Centipedes, spiders and insects of all species are considered errors. Thus, while the insect is always a mistake, a mistake is not always a mistake. Although the difference is not usually a matter of life or death, it is always good to know the difference between different types of errors. In most people tend arachnids (spiders fall into this category) are insects, because their errors are considered. That’s not true, but. There are very real differences between insects and arachnids. Insects have three body regions. Has a head (explicitly), a chest, which is the central part and the abdomen. If you look closely at an insect, you will notice that the legs of an insect (insects have six legs, and only six legs? No more, no less) attached to the chest. If you look at an insect, it is clear that there are three different sections. In addition, certain insects (not all) have wings. N spiders have wings.
Spiders, however, have eight legs and two body sections: head and abdomen. Arachnids are named after an ancient Greek legend. It was said that Athena was a woman named Arachne boasted that its fabric was better than anyone, including the goddess? S weaving. Greek gods and goddesses are not all mortals, so Arachne was turned into a spider. She could weave their webs, spiders, and all bear his name. Despite these differences between insects and spiders are, there are also similarities. First, two types of insects have an exoskeleton. This means that the skeleton is outside the body, rather than inside. Even if we as a people, a skeleton that protects some organs, it is always below the skin. And in areas such as legs and arms, the skeleton through the muscles and skin is protected. With insects, the skeleton on the outside and protects the interior and more. Some have hard exoskeletons, like black widows and cockroaches. Another similarity is the eyes. Both insects and arachnids have eyes that can see in several directions simultaneously varied.

Basically, as cockroaches are unpleasant and uncomfortable for most people simply by their presence. Tend to live in a variety of environments in the world, but prefer warm areas and conditions, often in buildings and structures. Leave chemical traces in the feces and pheromones emitted and swarms of mating. This serves the purpose for which they are capable of mechanically transmitting disease organisms such as bacteria and viruses, food poisoning and other ailments. Read the rest of this entry »
