Caterpillar diseases

Maybe something fungal or bacterial? Or parasites. (for example, riders, this happens very often). And the one that hangs upside down is most likely going to shed (it's too early to pupate, isn't it?)

No... She wasn't going to shed, she was dead. And how to treat this muck in general? What kind of prevention should I do for other caterpillars? Do these parasites pose a danger to humans?

Well, not for a human being.
Unfortunately, I don't know how to treat it...
In general, as far as I know, the caterpillars of swallowtails are kept one at a time. That is, for one caterpillar - one jar (well, or another container), for another - another, and so on.

yes, as my sad experience showed like this: they do not need to be kept, they injure each other and die from damage

If the caterpillar is limp, then most likely it died from excessive humidity/ lack of ventilation. Very many species do not tolerate high humidity and, if they do not die suffocating, they grab the infection and die later. Whether this is true or not, you can tell if you post a photo of the cage where you keep swallowtails. In this case, it is advisable to plant the caterpillars one at a time in well-ventilated cages, put the feed one at a time and change it more often. Soil, especially moistened (planted dill was watered?), do not!!!. To prevent the dill from drying out, you can wrap the sections of the stems with wet cotton wool, and a piece of celofanchik and tie it tightly with a thread or tighten it with thin tape.

Judging by the appearance of the cage, they probably died from too much humidity. The forage plant should not lie so tightly, it should stand and be well ventilated.

A month ago, I brought 100 kaya caterpillars from a trip to the region, only 2 of them pupated.all other flies

Judging by the appearance of the cage, they probably died from too much humidity. The forage plant should not lie so tightly, it should stand and be well ventilated.

no, I personally saw how they fought, + when there was one left, it successfully grew and pupated, because I often kept this box open and only covered it at night

And the box, yes, is a bit cramped for such large caterpillars...

I measured the humidity in the cage itself - the value from 46 to 51 slowly rose, and stopped at 52. Temperature 28°C. I planted one caterpillar - I want to see how it will survive in some conditions. I cover the cage at night with a double layer of gauze (the caterpillar of Kaya 2 weeks ago already escaped), the caterpillars are always standing on the balcony. I don't want to watch them fight. I attach a photo, please rate it:

I'm thinking, maybe replace the earth with sawdust (ground to powder)? And dill will be plucked in small portions, and so give.

The soil in the first cage looks damp... The soil must be absolutely dry! Although, in general, it is absolutely not necessary for Swallowtails.

Dill shoots need to be plucked and put in water. Plant the caterpillar on dill, and so that it does not go away, put on a "sleeve" sewn from a grid on the escape. From the bottom and top, tighten it with an elastic band. Then it remains only to change the dill as it is eaten. All this is desirable to put on the street, in the shade, to be blown by the breeze. You can also cover the growing dill directly in the garden with a net.

From my own experience, I can say that swallowtails very often die for unknown reasons on purchased dill. And it's best never to use one. In general, they grow perfectly on snyti, which in my opinion grows everywhere.
The disease can provoke any stress. Both waterlogging and drying of the feed. Usually, caterpillars get sick quickly when feeding wet leaves in the absence of good ventilation. If you keep the plants planted in pots open, then you can at least spray them - they will not die from this, as a rule. What matters is not so much humidity as good air quality.
Some diseases are highly contagious and if the dead caterpillars are not removed immediately, they all get sick within a few days.
You can put plants in water, but the option of not putting them in water and changing them more often is safer for caterpillars. My swallowtails grew well by the hundreds for several generations in completely open low containers in a fairly high density, with a daily toss of fresh leaves. The leaves should lie loosely and in a thin layer. It is advisable to put a paper towel on the bottom and change it once a day.
The risk of mass epidemics can also be reduced by decontaminating plants. To do this, you can spray them with chlorhexidine or something like that and, when the leaves are dry, give them to geese. But if the epidemic has already started, it is usually ineffective.

...Some diseases are highly contagious and if the dead caterpillars are not removed immediately, they all get sick within a few days...

Absolutely correct, but even if you remove the dead, others may have time to get infected. It is better to prevent the epidemic by monitoring the humidity and freshness of the feed, than then to nurse the survivors (in my experience with pear peacock eyes).

...You can put plants in water, but the option of not putting them in water and changing them more often is safer for caterpillars...

As a compromise, you can use cages from 2-liter bottles of mineral water. We cut the bottle, stick a tightly fitted foam cylinder into the neck, put the stern and pour water into the bottom of the bottle, settle the tenant, tighten the mesh. According to this scheme, it is quite easy to change the feed, the cage is easy to clean (gus. selim only in dry!!! sadok).

I took a three-liter jar, planted dill and plantain there, watered it well, and placed the "pets". ...

It is very lucky for you that in such conditions (high humidity and poor ventilation) they were able to survive. It's better not to do that!

I just want to give you some advice so that nothing gets moldy.
I have been actively breeding the daytime peacock's eye for 4 years now. My cage is a food container.Food standing next to an open window or on the street, covered with gauze in one layer. I change the nettle (I tear off the leaves and bring them) every 2-5 hours, I clean the cage 2 times a day. Inside there are many sticks-threads for pupation. And no diseases other than parasites! Sometimes I arrange a "rain"
But after 2 hours I will definitely wash it. Of the 50 pupae, 40-47 are normal, I release them. But at night sometimes I also Bring food

  
... For this reason, I recommend only a small goose to beginners, especially kaya)))

Well, nighttime night discord, there are easy types, and there are extremely complex types (I have been breeding different gus in more or less numbers since I was 8 years old). It is one thing to feed gus. ursa bears (I started with them), and another-steppe species of scoops (for example, Periphanes delphinii) or the same Saturnia pyri, which live in the crown of a tree and immediately get sick without fresh air.
And many types of bears (our Crimean ones - rural, kaya, Geba, Hera, nettle, beggar, bloody) are really quite easy to breed.

However, there is one good rule: in order to successfully breed any gus. you need to carefully read about the biology of this species - in which biotopes it lives (dry, wet, sunny, shady), lives in groups or alone (you need to remember about such a phenomenon as canibalism in some species, for example, pigeons), what it eats(and the easier it is to feed), how it pupates, etc. And then it will be clear: what conditions and, accordingly, the cage need to be prepared for a particular caterpillar.

A very important point!
But I would not arrange a" rain".

My cage is also near the open window. By the way, this morning I found a pupa How long can it be in this state?

It all depends on the specific type. I had from 4 days to 3 months (daytime)

If you quickly clean and wipe dry, I believe that nothing will happen to the daytime ones-I don't put nettles in the water and the leaves may not be juicy. I have in 2010 6 caterpillars withered and died

Make it rain and wipe everything dry right away - I don't know what the point is.
If there is food, healthy caterpillars do not wither.

Papilio Machaon

For mach-10-20 days, depending on the temperature. I think 12 days at 26 degrees.

How to properly keep wintering caterpillars? I put my first "batch" in a box with pupae and left it on the balcony at a temperature of -10-15C. Almost all the pupae came out with butterflies, and the caterpillars were dry by December! Maybe it's some kind of virus?

You need to know the species, besides, I think this question is better to write in "How to get a butterfly out of a pupa or caterpillar"

here's a similar question. I have 4 polyxena pupae since the beginning of June. As far as I know, they only fly one generation per season. tell me, if without wintering, when to wait for the release of imago? maybe someone has experience in removing polyxene?

Can a swallowtail pupa get sick???

Who can tell you what is the cause of caterpillar death?

Similar problem. I recently found 3 wine hawk moth caterpillars and put them in one terrarium. The first of the caterpillars stopped eating and 2 days after landing in the terrarium began to spit out (I can't call it anything else) along with the fikali themselves (but did not die). Three days later, the third (most adult) caterpillar unexpectedly died, it simply flowed out through the anus, although there were no prerequisites the day before. I realized that this is a disease that is transmitted and quickly removed the last (without signs of illness) caterpillar to another terrarium. Maybe it was because I planted them together. (Although tobacco hawks lived quietly in the same terrarium and everything was fine).
My mistake was that I did not remove the caterpillar, which was behaving suspiciously and clearly abnormal. Now I'll see if the last caterpillar survives.
Now I'm thinking about whether to plant two poplar hawk moth caterpillars together (they are still small, 3-5 days after birth).
