Butterfly with colorful wings
Few people have a childhood where they didn't skip school or chase butterflies after gluing jute sticks on some sunny afternoon. What is there in the butterfly, for which the eyes of the parents are painted or the sun burns, the children run behind him? What is not in him? Butterfly is a wonderful creation of nature. It is so wonderful when they spread their wings and dance in the air, sit on the leaves of a small tree by the wayside and talk to the flowers. Like its colorful wings, its bold design. Many people think that with the color and design of the wings, they attract the little ones very close. It might do that, but their fancy design wings have a lot more to do. They walk around in the sun, but it's not like that. They need sunlight to survive. They survive by eating (absorbing) the sun with these colorfully patterned wings. Patterned wings also help to identify who is a member of a family or who is a relative. Just as impetuous teenagers chase after them for fun, there are many other members of nature who are eager to eat butterflies. Especially for birds, butterflies are very favorite food! They chase butterflies whenever they get a chance. To avoid the eyes of such birds and hide in nature, colorful wings are very beneficial to butterflies. Sometimes it can also be used to intimidate many enemies. The color means there is some poison in it, and the taste is oddly bitter. Because of this, many enemy birds or animals do not trample their shadow.
Mysterious mountain Bayan-Kara-Ula
How many mysteries accumulate in the mountains! Most of these mysteries lie beyond our eyes or knowledge. Such as the case of Bayan-Kara-Ula mountains in China! More than 60 years ago, Chi Pu Tei and his team were conducting an archaeological expedition in this region of China. Suddenly they found a row of caves. However, they were surprised when they found the caves in detail. The cave contained several tombs and among them some strange skeletons, with unusually large heads, narrow legs, and thin faces. At first, archaeologists mistook it for monkeys. Later they realize that monkeys never bury themselves. On top of that, some stone discs were found in the tomb, which look like gramophone records. There was a round hole in the center of the discs. But from the size and style of the disc, everyone guessed that it was undoubtedly the work of a very advanced man. There was also some writing on the disk in small letters. More than 700 discs were recovered from this cave. But the incident happened twenty years later. No one has been able to decipher the mystery of the script on the disc. Finally Sum Um Nui deciphers the writings and is shocked. Nooyi's discovery was so explosive that it was suppressed from government circles.
Later it is known that these discs are written by aliens! Aliens came to Bayan-Kara-Ula according to the text. For some reason their spaceship crashes. As a result, the return road of those aliens is closed in a sense. There is a legend in the region of a man with a crooked, yellow face who descended from the sky. The appearance of these aliens was so terrifying that the tribal groups of the region attacked them. The appearance of the aliens depicted on the discs bears a striking resemblance to the skeletons in the cave of Bayan-Kara-Ula. But those skeletons are not actually human? Does this information prove that aliens had contact with ancient civilizations? Not sure exactly.
But interestingly, there is a tribe called 'Dropa' in the region between Tibet and China. It is said about these Drupas that their ancestors came down from the stars of the sky. Bayan-Kara-Ula is a remote place, and this mystery is very much in keeping with the nature of the region. Whether the aliens really came or whether the Dropas are really descended from aliens, the nature of Bayan-Kara-Ula no doubt knows these answers. But he will never reveal the secret.
A frog's umbrella is not a frog's
Mushrooms are commonly known as frog umbrellas. The actual body of the mushroom is a microscopic thread-like structure called mycellium, which grows on a substrate or underground. When mature, many mycelliums join together to form a single structure and rise to the surface of the soil to form an umbrella. Most frog umbels belong to the class Basidiomycetes, one of whose characteristic features is the location of the spore-bearing gills beneath the umbrella-shaped structure. The umbrella of the poisonous frog is called a toadstool. Some species are edible when young but become poisonous or unfit for food when mature or start to rot. Common edible mushrooms are species of the genera Agaricus and Pleurotis. It contains proteins, sugars, valuable salts and various vitamins. Because of these elements and being low in calories, frog umbrella is an excellent food for heart patients. Out of about 20 species of frog umbrellas in Bangladesh, 5-6 are poisonous. Poisonous species include the genera Lepiota and Amanita. Forest Some frog umbrellas are eaten by tribals of Chittagong Hill Tracts. More recently, mushroom cultivation has been going on in a few small farms. Mushroom Cultivation In ancient Greek, Roman and Indian literature, the frog's umbrella is described as a coveted food of royalty. The first commercial cultivation of mushrooms began in Europe at the beginning of the 20th century, and more recently in Bangladesh. In the early eighties of the last century, mushroom cultivation started under the initiative of the Bangladesh Agricultural Research Council, after which the 'Mushroom Cultivation Center' was established at Savar. Species approved for cultivation are White buton mushroom (Agaricus bisporus) and Oyster mushroom/Wood fungus (Pleurotis sajor-caju, P. flabellatus, P. ostreatus) Oyster species are readily available and more popular in Bangladesh. The main inputs for cultivation are rice straw, bran, sawdust, cotton waste and a mixture of other agricultural by-products. Cultivation in polythene can be done in greenhouses or huts. The entire preparation takes 35 days. The crop can be harvested within 10-15 days after sowing. Cultivation can be done throughout the year, but oysters can only be cultivated in winter. One cultivation can produce crops for up to two weeks continuously. Frog umbrellas can be cooked fresh or dried and preserved.
