Recent estimates indicate approximately 11,000 species described so far. There are many species, especially in wet tropical forests.
Traveling grasshoppers, driven by the dominant winds, can fly without interruption 2000 km, at a speed of 40 km / h, which gives them a considerable devastation surface. No other insect is so resilient.
Grasshoppers prefer to eat herbs, leaves and grains. Some will tend to eat from one type of plant, while others will eat from a variety of sources throughout the day. Only one of the 8,000 grasshopper species will only eat from a single plant species.
Grasshoppers hunts during the night also the crickets who sleep. Among the grasshoppers there are some species that are self-defeating. Insensitive to pain, they begin by eating their front legs, then the back of the body. This does not make him out of food.
In some countries, grasshoppers are consumed as a good source of protein. In Mexico, for example, they are appreciated for their high protein, mineral and vitamin content. They are usually collected at sunset, using lamps or electric lighting, or nets.
Sometimes they are left in the water for 24 hours, after which they can be eaten raw or boiled, sun-dried, fried, flavored with spices such as garlic, onion, chili, and added to the soup. They are abundant in the central markets of Mexico.
The sensory organs are on the outside of the body and consist of tiny hairs that are each specially calibrated to respond to a particular stimulus.
Grasshoppers also have timers for sound reception. They have a masticatory mouthpiece and the heterometabolic development. He possesses tympanic organs, and masculines a stridatory device.
The timings are placed on the sides of the first abdominal segment and the stridatory organ consists of a protruding longitudinal rib of the tegmine and the femurs of the posterior feet that are moved as an arcus on the rib.
In some African countries, locusts are an important source of food because, alongside other insects, they bring protein and wheat to their daily diet, especially in times of food crisis. They are often used in soup. Grasshoppers eaten in Uganda and neighboring areas are called Nsenene, but they are, in fact, Bush crickets.
The reproductive system of the grasshopper consists of gonads. During reproduction, the male inserts the sperm into the female eggs by means of very thin and fine calane.
Then the hen clots the eggs and deposits them at 10-15 cm in the ground, and they can also be deposited on the roots of the plants or in the stable, for example.
Packed eggs look like thin rice grains. They stay like this in winter until spring when the temperature is warm enough. In temperate areas many grasshoppers spend their lives in the egg, the males only live for three months.
The first nymph coming out of the egg digs to make room for the surface, and the rest will use that ditch-ready road.
