Bringing the shield nymph to the imago

Yes, no matter how much more than one person was engaged in growing insect larvae in order to get an imago in the collection. But so that the imago gets the desired color, depending on the temperature... Perhaps you will be the first, at least in the case of bedbugs. Try keeping it on a glass-enclosed balcony facing the shady side of the house, if there is one. If not, then on the bottom shelf of the refrigerator.

And what plants are suitable for feeding the shield, are they just universal polyphages or do you have preferences?

Probably the ones you found it on. In general, they love fruits and seeds (especially unripe ones).

Plants should be straight live or torn off leaves will be enough?

They suck, so there should be juice inside. And the torn leaves quickly wither. Place the branch with the leaves in a bowl of water. But it is better that there are not only leaves, but also fruits. I repeat: scabies are very fond of fruits, both juicy and unripe dry.

Indeed, this can be done. Pentatomids feed on fruits and seeds.

Basic information:

The green woodcutter Palomena prasina L. is widespread in the forest-steppe and forest zones of the Palearctic (Rider, 2006a). It is a broad polyphage: it develops on more than 100 plant species (including herbaceous and some garden crops), and can feed on woody (maple, ash, birch, elm) and shrubby species (alder, viburnum, caragana, hazel, etc.; Southwood and Leston, 1959; Puchkov, 1961b, 1987; Asanova and Iskakov, 1977, et al.). Young larvae suck mainly vegetative parts of plants, while older larvae and adult larvae develop on generative parts. Buckthorn can cause significant damage to hazel and some other plant species.
Palomena prasina overwinters at the imaginal stage in the forest floor. In the forest-steppe zone, overwintered bedbugs are activated and fly to open and warmed biotopes in mid-May, mate, and after 2-3 weeks the females begin to lay eggs. Oviposition is extended until mid-or late July, by which time most of the overwintered bedbugs have died.
Eggs take 7-8 days to develop. The larval stage lasts about two months, but can be prolonged, as indicated by Puchkov (1961b), even up to three months. Mass migration of adults in the forest-steppe zone usually occurs in the first half of August.

At this time of year, whatever you find will be fine. But try to give some variety. And always cotton wool with water and cutting the shoots of plants so that they can suck the juices.

The temperature is about 20 ° C and the daylight is short (no more than 11 hours of light).

The imago color. The adult will be green after molting. Almost certainly, the color of the adult changes after molting, I think after two weeks - when it is in conditions that stimulate diapause (short day, low temperature). The diapause itself is obligate.

The bug has reached the imago stage, before that I kept it in a room. Is it possible to take it out on a glazed balcony for the sake of changing its color, if the daytime temperature is 14 degrees, or is it already too cold for it?

14 it's a little chilly... Hold it for a week on the window, but in the room and feed it well, then transfer it to the balcony, but so that the day is short, i.e. so that the evening electric light from the window does not fall on it, so that it gets dark for it like in nature. And keep feeding and watering. There is a chance that it will change color in a couple of weeks. But this is not a guarantee...

Thanks for the tips, there are already brown tones in the color of this individual, does this mean anything? It is also much smaller than the shields that were found in nature.

Interesting. I'm somewhat surprised... We conducted an experiment with this species, but it was a long time ago and it was mainly conducted by my supervisor (A. Kh. Saulich, 1995 approximately). I don't remember how long after the winging we kept the imago. I think they were green. That's why I assumed that they will be green at first, and darken in the short day of the week in 2.

Take a photo of them.

Does the color tone change?

You can't see very well here, but the color is not uniform-green.

and after molting in 1-2 days it was exactly green? After how many days did it start to get dark?

There was one right away.

The bug doesn't move for some reason, is it dead, or is it already hibernating?

If it's warm and doesn't move at all, then it's not hibernation. Either it pretends to be dead (but this is if the condition lasts only a few minutes after braking), or it is really dead.

The bug moved for a while. If he died, why? There was water and food.

from the photo, it seemed to me that the color was unhealthy. It happens. The reason is difficult to name. Maybe the water didn't fit. Or there were traces of pesticides on some feed. Or some kind of damage during molting (although the wings are fine, but there may have been damage to internal organs) or during capture. Or parasites. And the food - were there leaves or seeds, nuts?

There were berries, leaves, and shoots.

maybe I should have given them some seeds. we were driving on Karagan, but it was at the beginning of the summer that truchki was available.

you can't usually find the reason.

Is it possible to talk about some kind of deviation, or is the variability quite normal? Here it is in comparison with the usual prazina.

is Paul alone? Not different? small, of course....

I don't know, but I think that the male, after all, like the female is usually larger. Without an autopsy, they can't be distinguished? In addition, the prazina I compared it to was small itself, the largest ones were about the size of the marble bug on the left.

of course, the sex can be determined without an autopsy. females have a longitudinal slit, while males have a fork - like shape. Just like on page 8 in the presentation.

Last year, in August, I caught the imago Holostethus strictus vernalis, when the pin was pricked, the bug looked very bad and deformed, I thought that the imago was soft and young. Today I caught a bug of the same species, also very soft to the touch, how long does it need to be "held" so that the covers become hard? Or is this softness of the skin a feature of the species?

Can you tell me what plants can be fed to imago Sciocoris-a?

It depends on what kind, but in general they are omnivorous. More precisely, you can see in the Fauna of Ukraine, Puchkova V. G., 1961. It is in Ukrainian, but the names of plants have Latin. Or Yessenbekova_2013_Hemiptera (Heteroptera) Kazakhstan, although many data on trofik are mostly taken from previous work.

I'm trying to raise two acanthosomatid nymphs (I don't know the species), but I ran into this problem: they don't eat anything at all. I put them unripe berries and hawthorn leaves, leaves and seeds of nedotroga, they never ate, they move very sluggishly. There is cotton wool with water. What to do?
