How does a caterpillar turn into a butterfly?

Have you ever interacted with people who claim that butterflies never eat? And this is true for some types of butterflies, and the reason for this is the process of its transformation from a caterpillar.

During her life, the female lays from 100 to several thousand eggs. She tries to place them on those plants that will be useful for her offspring. If there is only one such plant in the area, then it is on it that she will lay her eggs!

These eggs hatch into tiny, worm-like larvae called caterpillar larvae. They begin to eat and grow, during which time their skin has time to peel off several times. All the caterpillars do during this period is eat and eat, stocking up for the rest of their next life, when they turn into butterflies. Food is deposited as fat, from which wings, legs, suction tubes, and everything else that distinguishes a butterfly from a caterpillar are built.

At a certain moment the caterpillar feels that the time has come for a change, then it weaves a small cocoon around itself, its head falls off and the caterpillar skin is shed, after which the chrysalis appears. Then she pierces the cocoon with a sharp needle at the end of the torso.

The pupa can sleep for several weeks or months. However, at this time, changes occur in it, so that it comes out as a fully formed butterfly, but at first it does not fly. She sits for several hours, spreading her wings, waiting for them to dry and get stronger. She waves them until she is sure she is ready to fly - after which she makes her first flight.

By the way, the life history of moths is exactly the same. Did you know that there are many more different types of moths than butterflies!

How did the pseudonym of the Ukrainian singer Ani Lorak appear?

Ukrainian singer Karolina Kuek became known under the pseudonym Ani Lorak thanks to the competition "Morning Star-95". The fact is that another Russian singer under the name Carolina was already announced there, so the Ukrainian woman had to get out of the situation by writing her name the other way around.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

FN Evolys ultralight machine gun 16.09.2021

The Belgian company FN Herstal presented the FN Evolys ultralight machine gun at an arms exhibition in London.

The machine gun will be available in two versions, caliber 5,56 mm and 7,62 mm. One of the main features of the FN Evolys is its weight, which is only 5,5 kg in the 5,56 version and 6,2 kg in the 7,62 mm version. For comparison, the weight of the equipped RPK, which is used in the Armed Forces of Ukraine, is 5,46 kg.

According to the developers, the machine gun combines the ergonomics of an assault rifle and firepower with belt feed. This is an unprecedented advantage in the existing arms market.

The FN Evolys is a new type of machine gun that will complement the existing line of FN Minimi, FN Mag and FN M2HB-QCB machine guns.

Characteristics of the new machine gun:

A two-way fire switch with a semi-automatic firing mode.
The effective firing range is 800 meters (5,56 mm) and 1000 m (7,62 mm).
Rate of fire - 750 rounds per minute.
Stock adjustment in height and length.

FN Evolys also has a rail that allows you to install different types of sights. The weapon can be supplemented with a bipod for greater stability when firing.
