A spider with an egg cocoon and baby spiders was discovered in Burmese amber

Spider with cocoon

Surely many of you have met a spider running along the ground with some strange white ball stuck to its abdomen? This is how mother spiders carry a cocoon of spider webs with eggs, from which spiderlings will hatch in the future. In the photo you can see a female wolf spider (Lycosidae) with beautiful gray-brown fur and a white cocoon with spider eggs attached to her abdomen. If you look at this cocoon enlarged, it looks like a white golf ball. The eggs protruding under the cover of a dense web form tubercles similar to the bumps of a golf ball. Interestingly, the web cocoon is used for offspring even by those spiders that do not weave hunting webs, but simply hunt, like the wolf spider captured in the photo.

After fertilization, the female looks for a secluded place. There she weaves a spherical cocoon where she lays her eggs. The female wolf spider wears the cocoon on her body for several weeks, where it is attached to the tip of the abdomen using a spinneret. The rate of egg development depends on temperature, so the expectant mother begins to spend a lot of time in the sun, and not hide in the shade during the day, as before.

When a female wolf spider is carrying eggs, she spends a lot of time in the sun, as the eggs develop faster at high temperatures. Due to dehydration, she sometimes loses up to 30% of her weight! But the maternal instinct is stronger, and the female endures this torment for the sake of the offspring.

If a cocoon with eggs is taken away from a female, she will still experience anxiety for several hours and wander around the place where the cocoon was taken from her, in search of her offspring. A female whose cocoon has been taken away may carry a piece of cotton wool or even plasticine instead. There is a known case when a female Pardosa riparia, a small species, began to carry a cocoon of a much larger species of Pardosa amentata, which was four times larger than her own!

When the spiderlings emerge from the eggs, the mother breaks the cocoon with her powerful jaws-chelicerae, and the spiderlings, one by one, move onto her back. When the very first spider leaves the cocoon, it leaves a web along which all its brothers and sisters climb onto the mother. Until their first molt, they do not get off their mother's back and do not eat anything. Then the female finds a suitable damp, shaded place, the spiderlings descend to the ground and begin to live on their own.

The nervous system of wolf spiders is one of the most developed of all spider species. This is due to their rather complex lifestyle - the need to hunt prey, complex mating rituals and the process of bearing offspring.

Nest creation process

Building a nest for a female tarantula is a very important moment. In most cases, individuals prefer the far corners of the aquarium to place their nests in it. It is very important to have a support on which the web will be attached from different sides.

When the spider has decided on its location, it begins to weave a kind of hammock. After the female completes the construction process, she begins to gradually lay eggs at the very bottom of her nest.

In appearance, the eggs resemble a yellowish paste, on which you can see small eggs of various sizes and shapes. The spider's belly gradually decreases in size and takes on a devastated appearance. Gradually the female forms a hammock shape, creating a spherical appearance.

In order for the future offspring to be healthy and strong, it is important to monitor the temperature in the terrarium while the incubation process is taking place. If the humidity level exceeds acceptable standards, the eggs may begin to rot. In this case, the mother can eat them.

Best skills

The robber has many useful skills. To start the game, it is recommended to take “ Sharpie ”, as this will allow you to build an additional “ Thicket ” or another “ River ”.

• “ Sharpie ” gives you a 10% chance to keep any card after placement. The only thing is that the effect of the skill does not affect gold cards.
• “ Picky ” is a wonderful option for a robber. The character will receive fewer items, but their value will increase. This will help you obtain useful equipment in the future, so this skill is extremely important.
• “ Nothing is sacred ” is also effective. Restores 3 HP for destroying an enemy unit. The result will be a kind of improved vampirism. Thanks to this skill, the Trickster can fight multiple opponents without any problems.

The character and lifestyle of the cross spider

Most often, the spider chooses the crown of a tree for its permanent place of life. Thus, he immediately creates both a trapping net (between the branches) and a shelter (in the thick leaves). The web of the cross spider is clearly visible even at some distance; it is always round and even and quite large.

The household crossmaker carefully monitors the condition of the threads in the web and makes sure to completely renew it every few days. If a large web becomes a trap for an insect that the spider cannot handle, it breaks the threads around its prey and removes it.

Replacing an old trap with a new one most often occurs at night, so that by morning it is ready for hunting. This distribution of time is also justified by the fact that at night the spider’s enemies sleep and pose no danger; the spider can do its work calmly.

It would seem how an almost blind spider can build such complex structures in complete darkness! However, in this case it is based not on vision, but on touch, which is why the network is always so smooth. Moreover, the female weaves the net according to strict canons - it always maintains the same distance between the turns, there are 39 radii, 35 turns and 1245 connecting points.

Scientists have found that this ability is inherent at the genetic level; the spider does not need to learn this - it performs all movements unconsciously, automatically. This explains the ability of young spiders to weave the same web as adults.

The consequences of a spider bite can be unpredictable, since its venom is toxic not only to insects, but also to vertebrates. The poison contains hemotoxin, which has a negative effect on the red blood cells of animals.

It is worth noting that dogs, horses and sheep are resistant to the bite of the cross spider . Due to the fact that the poison is toxic, and also that the spider spider bites and can even bite through human skin, there is an opinion that it is dangerous for people.

But these are all prejudices. Firstly, the amount of poison released during one bite is too small to harm a large mammal, which is a person. Secondly, the poison has a reversible effect on vertebrates. So the cross spider is not dangerous (with the exception of people with individual intolerance).

Small deck

The Rogue is most vulnerable early in the game. Therefore, it is recommended to focus all your efforts on just a few cards. One or two keys will do. You won’t even have to waste your energy on the rest.

You shouldn't rely on quantity here - it's much better to focus on the quality of the cards.

“ Bookstore ” is suitable for the initial draw. Also, don’t be afraid to use “ Spider Cocoon ”. By the way, it’s worth adding a few words about this card, because it plays a special role in the Trickster build.

Spider cocoon

This may seem like a pretty scary card. However, you should not immediately have a negative attitude towards “ Spider Cocoon ”. Because it is useful in its own way.

Several spiders will appear on the way at once. The enemies are not easy for a rogue, but due to their number, you can get a whole bunch of useful cards. After all, the more enemies, the more loot. Therefore, you should not be afraid of the “ Spider Cocoon”. On the contrary, it is better to play this card as quickly as possible.

Forge shop

The Rogue obtains equipment through the trophy system. Each enemy drops a token, which is then exchanged for weapons and armor. But at the same time, the robber does not always receive effective items for combat. So this card will be an excellent solution to this problem.

“ Blacksmithing ” allows you to turn useless equipment into a powerful buff that reduces damage taken. The Rogue initially has problems with defense, so the defensive effect would be a great addition to the character's items.

Arsenal

The map will be unlocked along with the smelter. Adds an additional slot to the character for placing amulets. Therefore, in the future there will be fewer problems with the amount of magic the Trickster has. This is a very important characteristic. When choosing a new amulet, you should pay attention to the increased bonus to magic. If you choose correctly, this will allow the robber to no longer return to this indicator.

Other characteristics of the Trickster are improved with the help of other equipment.

Mountains and Dunes

Very similar cards in effect. “ Mountain ” increases the robber’s health, and “ Dunes ” reduces the HP of all opponents. It is recommended to use both to make the battle easier.

Mountain cards have a negative effect. If you place them on a 3x3 square, then harpies will inevitably begin to spawn there. They can cause a lot of problems for the character, especially early in the game.

Forest and Thicket

“ Forest ” in conjunction with “ River ” is very useful. The latter doubles the effect of cards located nearby. You can also use “ River ” together with “ Thicket ”. This will increase attack speed by as much as 4% (instead of 2%). Since the robber has a very good indicator, it makes sense to place a full bet on him.

There is a special combination with “ Dunes ”! In conjunction with “ Thicket ,” it turns out that the character’s attack speed increases, while that of monsters, on the contrary, decreases. This combo allows you to deal with even the strongest opponents.

Brief description of eggs and cocoon

Spiders lay eggs in a web cocoon. It consists of two layers, between which there is a loose layer.

The web protects the masonry from the following dangers:

• drying out;
• mechanical damage;
• bacteria;
• parasites;
• fungi;
• temperature jumps.

Basically, spider eggs consist of a nutritious yolk. They are covered with chorion and vitelline membrane. Quite elastic to the touch. With strong mechanical stress, the shell is very easy to destroy.

The color of the shell may vary depending on the species. In the nests of different species you can find almost all the colors of the rainbow, in addition, these colors can be very bright.

Some eggs are poisonous to mammals. Moreover, their toxicity does not depend on the degree of toxicity of the spider that carried them. An animal that eats such a clutch may die.

The cocoon consists of a web, which is why it is painted white, but can have different shades. Sometimes spiders coat their webs with a special enzyme, which makes the shell dense. It protects the masonry from moisture and bacteria.

Spiders can hide cocoons:

• on the ground;
• under fallen leaves;
• under stones;
• attach to branches.

In some species, the web does not reflect ultraviolet light or reflects only some spectra, due to which the cocoon becomes visually less noticeable among the foliage.

Understanding the Strengths of the Class

The Rogue has a percentage boost to Counterattack, Evasion, Critical Chance, and Critical Damage. A special trait of the Trickster is vampirism. With its help you can recover right during a fight. However, it is very difficult for a robber to get good equipment. At the very beginning of the game, he often gets bad items.

Defense is the Dodger's weak point!

If a necromancer can ensure his own safety by summoning skeletons, and a warrior thanks to rapid regeneration, then with a robber things are different. You'll have to rely as much as possible on evasion. However, it's not all bad. As you progress through the game, the Trickster will improve his own characteristics and find new skills. This will make him feel much better in battle.

Best Equipment

Improving your magic reserve is an initial necessity. Therefore, the robber will need to stock up on amulets. Next, you can collect equipment and bet on critical chances and damage from attacks.

Don't forget about evasion. This characteristic is an important component when conducting combat. The logic is simple: the more opponents miss, the faster the character will be able to deal with the enemies.

What is a 3rd grade doll?

The pupa is an intermediate stage of development of insects that undergoes a complete transformation in the process of ontogenesis (see Metamorphosis). The insect does not feed and is usually motionless, but intensive internal restructuring occurs in it, during which the insect transforms from a larva into an adult—Imago.
