Irura bidenticulata, known as the purple gold spider, is a species of the jumping spider family.
- It was discovered in 2011 in Southeast Asia.
- The purple-gold spider is about 5-6 mm in size.
- Able to jump up to half a meter, which is used when hunting microscopic flies.
- Weave a web, but only as a safety net for long jumps (the web is released at the time of the jump and allows you to return to the place if you fail) and for building nests in which females lay eggs

Watch how water freezes on a soap film. Did you notice that all the figures that appeared are hexagons? And this is no accident! It is this hexagonal structure (and no other!) that water molecules acquire when their temperature drops below 0 degrees. Therefore, larger hexagons appear from microscopic hexagons due to the growth of water molecules. Here you see them!

Sometimes in the bathroom you can see an unusual insect, which is shown in the video. This is the common silverfish Lepisma saccharina, which loves wet places. They are mainly active at night and hide during the rest of the time. They can eat plant products - sugar, flour. Do not disdain paper and even glue. For humans, silverfish is completely harmless.

Interesting cicadas Phromnia rosea live in Madagascar. Thanks to their special fluttering wax threads located on the abdomen, they become like fluffy white flowers. These nymphs are entirely white, and many hairs stick out from the back of the body, which grow in different directions.
These wax threads are a hardened wax substance released by special glands located on the abdomen and other parts of the body of the nymph. From a distance, they can be mistaken for small white flowers of an incomprehensible appearance. This body shape is an excellent camouflage from birds.

The eyes of a dragonfly are made up of nearly 30,000 elements. They give her a 360-degree view.

It seems that the spider has a flower on its head. But in fact, this is a reflection of a flower in a drop of water.

Even in the process of evolution, insects realized that ants are COOL, ants were the elite, everyone was afraid of them, so some insects decided to be as similar to ants as possible.

Look closely... it's not a spider. The spider-tailed horned viper uses the tip of its tail to lure birds.

A urine sample under a microscope.
Look how beautiful she is 🤩 Here we see calcium oxalate crystals. Calcium oxalate crystals, more commonly known as kidney stones, clog the kidney ducts. It is believed that 80% of kidney stones are formed from oxalate.

Zoologists have proven that earthen bumblebees are able to play. In experiments, insects rolled wooden balls, even if they did not receive any reward for this. The behavior of the bumblebees met all the criteria of the game: in particular, it was spontaneous and voluntary. This is one of the first evidence that insects are able to play.

Representatives of spiders of the species Dolophones conifera are real camouflage geniuses! The drawing on their body exactly repeats the wood pattern. Also, for disguise, the spider is able to spread its body on a tree.
Such camouflage of these small spiders (their size is only 5-9 mm.) makes them invisible to predators during the daytime. It is at this time of day that they sit on the branches in anticipation of the night, with the onset of which they begin their hunt. These Australian spiders are not dangerous to humans as they do not have highly toxic venom.

The acne gland (Demodex folliculorum), which is only 0.2-0.5 millimeters in size, is found in most people and is usually harmless.
It colonizes the hair follicles on top of the sebaceous gland, usually on the face and chest, and feeds on sebum and dead skin cells without causing any problems to the owner.
The exceptions are massive skin lesions with iron glands: in this case, a disease called demodicosis may develop.
Scientists have found that the acne gland does not just parasitize on us - it learns to cohabit with us, turning from a parasite into a symbiont that enters into a mutually beneficial relationship with a person.
The sequencing of the genomes of the glanders showed that these ticks "refused" most of the genes found in relatives, absolutely minimizing their needs.
