  1. Pay attention to the behavior of the spider. Before molting, tarantula spiders become lethargic, refuse to eat, some species change color,
  2. Observe the activity of the tarantula. As a rule, before molting, spiders become inactive or remain motionless.

    Don’t worry, your tarantula spider is healthy, it’s just storing energy,
  3. Pay attention to how much your spider eats. Before molting, spiders refuse to eat from a week to several months.

    Do not be discouraged, after molting, the appetite will return to your tarantula spider,
  4. Take a closer look at the pose of the spider. During molting, the tarantula spider lays on its back, upside down.

    In this position, it is more convenient for him to climb out of the old skin.

Shedding at tarantulas

Fulvolineata calmly survive even a 40-hour stay in the water.

Julien and his colleagues explain what is happening this way: in the absence of oxygen, spiders switch their metabolism from aerobic to anaerobic (oxygen-free) mode.

On average, all individuals could survive without air for about 16 hours.

Scientists believe that this is due to lifestyle A. Fulvolineata (because their forest counterparts look Pardosa purbeckensis and parts of this time did not hold out).

“Many species of spiders live in places where from time to time they have to dive under water.

In most cases, flooding arthropods just climb up the accessible plants, but we have never seen spiders manage to “endure” so much time under water, ”says Petillon.

We are, of course, not talking about those arthropods that are able to drag air with them under water (for some it lingers on its shell, others weave special scuba nets).

The period of 16 hours may be due to the fact that in the salt marshes of northwestern France (in the area where they live A.

Fulvolineataa) tides rarely last more than eight hours. And even more so, it is unlikely that spiders will wait for two such arrivals of large water.

There is an opinion that spiders have developed their ability to weave webs specifically for protection from the water element.

Making a waterproof "door" for their home, they could well wait out the floods or long rains. A. Fulvolineata indirectly confirm this theory.

They almost do not create silk threads, and they do not really need this with their incredible exposure.

An article by the authors of the work will be published in the journal Biology Letters.

Arachnids do not have an internal skeleton, but have an external - exoskeleton. Muscles, ligaments and internal organs are attached to it.
This is a solid cover of the body, consisting of chitin and sclerotin. It consists of strong and hard areas, thin, soft and elastic areas, as well as tactile hairs.

The exoskeleton cover itself is called a cuticle.
The exoskeleton does not grow with the animal, therefore, during the life of arachnids, its natural change occurs - molting. The discarded spider exoskeleton is called exuvium.
Conventionally, molting can be divided into several stages:
pre-market - the formation of a new exoskeleton under the old,
actually molting is a change of exoskeleton,
postpartum - restoration of the exoskeleton.

Precautions during molting

This is a crucial period for any farmer, since the life of your pet and the successful outcome of molting will depend on the conditions created by you.

First of all, what you should pay attention to is the humidity and temperature in the terrarium.
The duration of all stages of molting depends on temperature. At low temperatures (below 22 ° C) they will take much longer. It is better not to do too high a temperature, it should be in the range of 22-28 ° С, depending on the type.
The humidity immediately before molting must be raised so that the animal does not dry out during molting, as it loses a lot of moisture.

To do this, you need to put a wide drinker and constantly moisten half of the substrate in the terrarium (for moisture-loving species), or only one corner (for dry-loving species).

A lack of moisture can cause stuck extremities in exuvia. In this case, the spider will amputate them. During the next molt, a new one grows in place of the lost limb, small and almost without hairs. After 2-4 molts, the limb is fully restored. Scorpions regenerate lost limbs more slowly and often remain without them for life.
There may also be an incomplete separation of the skin of the abdomen, and the spider remains with a dried up patch.

You can try to remove it when the spider will move and clean itself. Previously, you can damage the soft shell of the abdomen.

Before molting and after molting, spiders and scorpions do not eat, so the uneaten feed should be removed.

The best protection from bad molting is satiety and access to water at the tarantula. This supports the entire body and reduces the chances of unsuccessful molting.

Mold and fungus

You often could see a little noticeable white “mold” on the abdomen, do not panic, it’s just penicillin that could form on top of the shelter, and the spider could easily hook it, after molting everything will pass.

But mold that appears due to residual feed, etc. can be a real problem, and often appears in the abdomen where the body temperature is highest. If you notice mold in your terrarium, it is best to remove it immediately. It can spread to the internal organs of the tarantula and can lead to serious injury or death if measures are not taken in time.

Usually it has a white, yellow, orange color under the stomach or on the legs. Sometimes spiders themselves gnaw off their limbs in an attempt to stop further infection.

If you find mold on spiders in time, try to transfer it to a separate well-ventilated terrarium or container, and wash the old terrarium well.

If all else fails then an antiseptic solution or iodine diluted in water (approximately 1 to 10) should be applied and smear the damaged areas of the body. You need to repeat several sessions to get the result.


Humpback is a small midge that resembles a Drosophila in appearance. It is black, but much thinner and smaller.

This midge does not pose a threat to a large tarantula, but can spread dangerous diseases for a spider. If this midge is constantly in the terrarium, the spider may begin to stress. He will refuse food and will comb out the pile. Their larvae are much more dangerous if the capacity is small and the spider has nowhere to hide, they can easily eat the spider of the first links.

To avoid this situation, remove forage residues from the terrarium.

Try to get rid of midges.


White worms are or hang in the oral cavity. Sometimes appear in a drinker.

There are few treatment options, since this nature has been little studied. Immediately isolate the infected spider from the rest. Thanks to the midge Humpback or tweezers, the nematode eggs are easily transferred to other tarantulas.

If possible, clean the pet’s oral cavity from nematodes, you can use an alcohol solution, the main thing is not to overdo it. Most often, nematodes can be infected with natural spiders. When buying a new spider, keep it quarantined for the first time a couple of months.

Dyskinetic Syndrome (DS)

A rare disease that affects the nervous system of a spider, in which coordination of movements is disturbed (paws bend up).

The main reasons for the appearance of DS:

Mold and fungus. It occurs due to a low temperature of less than 20 ° C (in such cases, food is poorly digested, after which it can become moldy or become covered with fungus)

2. Poisoning by heavy metals that may be in the water.

It is best to give spiders 2/3 of the settled water, all the rest is simply poured, at the bottom all the metals, or boiled, are deposited.

3. Poisoning by pesticides with which feed insects and animals can be treated.

4. Infection with nematodes

If your spider is sick with this syndrome, you should not immediately plant it from the rest, no one else can be infected with it. Place the tarantula in an empty container, the drinker is not necessary, especially if the tarantula is less than 6 molting, the main thing is that one corner of the container with coconut soil should be wet. Set the limit temperature in the tray (+ 35-37 ° C). Not all species will survive this load. With this temperature, the spider can live no more than 5 days.

The main thing is to be patient, and do not rush everything and immediately experience the spider. Even after a successful molt, your pet may still have these symptoms, but with a slight improvement, and after 2-3 molts it will be completely healthy. Therefore, do not despair and bury your pet ahead of time.

We hope that this information was useful to you, and at least helped a little!

Shedding a tarantula.

In this article you will learn all about tarantula shedding, why it is very important for the spider, what conditions are necessary for successful molting, and you will learn how to determine what the spider is preparing to molt.

Tarantulas are animals that have an external skeleton. Throughout life, the animal grows when the skeleton becomes small, the spider drops it and grows at least one and a half times. Therefore, your animal will grow literally before our eyes.

One of the advantages of such an external skeleton is the ability to restore limbs.

If your spider is young and it happens that he has lost a foot, then after one or two molts, the foot will fully recover. The situation is worse with adults, as they do not fade often and the recovery process can be delayed.

But the paw in any case will recover, this is not so critical for the pet.

The situation is much worse if the tarantula damaged the abdomen.

There is a possibility that the inner skeleton may connect to the outer one and the spider will not be able to get out. Try not to let your spider fall, especially when it’s just eaten.

The most important task, both for beginners and experienced people, is to do everything so that the spider survives the molt and that it passes without consequences.

Tarantula molt goes as follows: first, the spider weaves a small crib from the web.

After the spider finishes making himself a bed, he lays his back on it. The outer skeleton sticks to the web, and the spider begins to crawl out of its past skeleton. If you see that the spider is lying with its paws to the top - this means that the pet is preparing for molting.

For successful molting of a tarantula, I recommend creating the following conditions:

  1. Maintain a temperature of 27 degrees
  2. Maintain air humidity at around 80 percent.

These parameters are easily controlled using modern digital devices.

A thermometer and a hydrometer are now combined in one device, and such a sensor costs about 300 rubles.

Young spiders are very easy to determine when they were about to molt. The back of their abdomen becomes black, and the spider may refuse to eat. In adult spiders, the color becomes slightly lighter, and the spider also refuses food.

Shedding of young tarantulas can take a maximum of a day, but adult spiders can lie for a very long time.

With each molt, your spider will grow at least one and a half times, its coloring will intensify, sometimes the character of the spider even changes.

The older the spider, the more it will show its character. Therefore, small tarantulas of aggressive species do not show much aggression, which cannot be said about adults.

If your spider is colored, then with each molt it will intensify color, enhance edging, amplify black tones. By the tenth molt, the spider will be in front of you in all its glory.

So, we repeat the main points of this article:

  1. Shedding a tarantula is a very important stage in the life of a spider, so you need to make sure that it goes well for the pet.
  2. If your pet accidentally lost a foot or two, then this is not so critical.

She will recover in a molt or two.

  • For successful shedding, it is necessary to maintain a temperature within 27 degrees and a humidity of 80 percent.
  • If your spider refuses food and his abdomen darkens
