Common North American Blue jay

Cyanocitta cristata, or Common North American Blue jay

Cyanocitta cristata, or Common North American Blue jay


An amazing thing, but there are a number of opinions that the blue jay is a deceiver by nature in all senses. It, they say, is not even blue! Those who held it in hands, note that the characteristic blue outflow of its feathers is due only to their refractive internal structure. If the feather drops out, there is no blue color in sight.
In American culture, the character is quite well-known and in general its reputation is bad enough. In southern African-American folklore there is a mention that this bird is the messenger of the devil himself! According to belief, you can’t find Blue jay on Friday, because it fuels the furnace of Hell. And on Saturday it sings happily, because the furnace of Hell is ready and the bird returns for our souls.
Mark Twain mentions the blue jay in the book “Jim Baker’s Blue-jay Yarn” and also not very flattering about this bird. The character of the book, Jim Baker, argues that jays are birds simply because they wear feathers and do not go to church, and so they are very similar to people, evil devils and liars, all this way.

Interesting facts about wonderful silk

Interesting facts about wonderful silk

Interesting facts about wonderful silk


Silk is one of the most valuable and beautiful fabrics. It was highly appreciated a millennium ago, and our contemporaries are fond of it. You know, it is produced from threads extracted from the cocoon of silkworm. The length of one such thread from one cocoon can reach 800-100 meters!
Silkworms are actually caterpillars, not worms. They build cocoons to protect themselves while they change into a moth.
By the way, some spiders also make silk. They weave silk webs to catch insects. However, the silk made by spiders is too thin for making cloth.
To process silk, the cocoons are first put in hot water. This softens the cocoons so the silk can be unwound.
Silk was such an important product during ancient times that the major trade route between East Asia, West Asia, and Europe was called the Silk Roads.

Interesting facts
1. The production of 500 grams of silk requires about 3 thousand cocoons of silkworm. It takes 12 hours of work to make a skein of silk thread weighing 250 grams.
2. Silk thread has tremendous strength, it withstands strong pressure and is very strong at breaking. Not so long ago it was found out that 16 layers of silk withstand a bullet from the Magnum 357 (with a lead core).

Mosquito – Itchy Situation

Mosquito - Itchy Situation

Mosquito – Itchy Situation


Only the female mosquito bites and leaves those itchy lumps on our arms and legs. She needs the blood for her eggs to develop. The humming sound we hear comes from the fast beat of the mosquito’s wings. The male mosquito feeds on nectar and other plant juices. Mosquitoes are part of a large group of insects called flies. A mosquito has two narrow wings, two antennas, and six long legs. A female mosquito usually has a mouthpart called a proboscis, which looks like a long tube. There are more than 3000 species of mosquitoes.
Mosquitoes are usually found wherever the weather is damp or where there are rivers, lakes, or swamps. That’s because these insects must lay their eggs in water. They even lay eggs in tin cans partly filled with rainwater. Mosquitoes have four stages in their life cycle beginning with the egg, then proceeding into a larva stage, followed by a pupa stage, and finally adulthood. When the eggs hatch, the young mosquitoes look like little worms.
