MANTIS:
(Filum)
They have three different parts of its body: head, thorax (where the legs and wings are) and abdomen.
A sack very rare, which seems poly-styrene, protects the eggs of the Mantis during the winter, until 200 nymphs can emerge from the sack. The nymphs resemble adults but are not the same size or have sex definition. It is possible that the colors and designs in the nymph stage are different to those in the adult stage.
Food:
The Mantis are predators eating a variety of insects, including moths, crickets and flies. They remain lying with the front legs in an elevated position. They monitor and resolutely stalk their victims even maybe eating each other.
Predators:
Spiders and other insect are the predators (including other mantis) eat the immature mantis. The birds feed on adult’s mantis.
Their compound eyes have the ability to view images and colors. Their three simple eyes distinguish between light and darkness. The simple eyes are placed forming a triangle between the antennas. The compound eyes are composed of many facets built with two lenses. These focus the light on a structure that has sensitivity to light (rabdoma), which is linked to the optic nerve.
ANTS:
(Orden: Himenoptera | Familia: Formicidae)
Number of species:
It is estimated that there are around 10,000 different species worldwide.
One of the most notable ants’ features is their social behavior. They live in colonies that usually consist of:
Queen:
one or more depending on the species. Their only mission is the egg-laying leading to males, workers and new queens.
Males:
their real task is to fertilize future queens. They come from eggs that once were not fertilized.
Workers:
Are females (without wings) that come from eggs that were fertilized. Their missions are collect food, care and defend the anthill. Women workers are not always
equal:
some species have two or more castes. As typical examples we can cite the "soldier ants" and the "pantry ant" that store food in its body.
The Females that at their larval state have received a special diet that differed from the workers are the future founding of new ant queens.
Males
These individuals have fully developed wings and disperse themselves in a nuptial flight. Females are fertilized only once in their entire life and store the sperm for ever. After copulation, the male dies and the female loses its wings. Then the new queen is dedicated to the construction of the anthill. At the beginning, it feeds on the reserves provided by their own muscle mass and later thrives with part of its implementation. It is responsible for raising the first generation that once developed performs the following tasks: repairs, expansion, cleaning and defending the anthill also collection of food and feed larvae and queens. The queen will enter in a security camera concentrates exclusively on the egg-laying which are transferred to other cameras for breeding. The larvae are fed and cared by workers.
There are different types of nests
Subways: they are carved underground.
Arboreal: the ants live in the interior of old trees or peel.
Do not build nest: it is possible that some species invade other ant species killing their queen and enslaving the workers.
Defense:
Most ants have no sting or this is not functional. The most used way of defense is biting and launching formic acid.
BEETLES:
The beetles are among the walking animals, but also among those who fly, which jump (such as the so-called spring beetle) and swimming (like the diver beetle). There are many species, some very intriguing.
CICADAS:
Among these insects, males courted females through sounds. As they do have neither voice nor lungs to undertake a serenade, they succeed by rubbing two parts of their body like cicadas.
Crickets, for example rub a wing against the other. And their wings are not equal each other: one has a rigid part, the scraper, while the other one has a cog that rubbed on it. It is as a quickly move of a saw on a stone.
The cicadas, however, have a membrane on both sides of theirs abdomen, called timbales. To make them vibrate they do it through certain muscles, pulling them into the body. Some air bags amplify the sound.
The vibration produced is very powerful, and you can feel it from more than one kilometer away.
ACUATIC INSECTS
They prefer calm waters, but in puddles, ponds, lakes and rivers around the world inhabit different species of insects. There are even some on the sea’ surface! Many insects in the water remain a part of their lives, but others are always, always there
The shoemakers or water bugs are very common in both freshwater (species of the genus Gerris) and salt-water (Halobates). They slide very quickly and easily on the elastic membrane which is the water surface, and therefore are also called "skaters". But do not get distracted, and they know distinguish water that suits them: when water hardly begins to move (for example, because it rains) slide to the edge to wait for the water calms down.
CRICKETS AND KATYDIDS:
The order of orthopteron includes grasshoppers, katydids, crickets and other similar. They are relatively large size insects provided with oral chewing organ, variable length antennas and well developed compound eyes.
But the most visibly are theirs developed third pair of legs, amended to jump. The femur and tibia very elongated, and with a robust musculature. Many are able to send and receive sound.
Though quite similar to the crickets, which are sometimes confused, grasshoppers and katydids belong to another suborder: are celiferus, while crickets are classified as ensiferus
Locusts are very voracious animal and highly mobile. In their migratory versions can travel great distances in groups of hundreds of thousands of individuals. A cultivated field can be completely razed in a matter of hours. |
