Spreading insects

  Help!
Beetles after staying in formalin (Barber's trap) for one week, have become stiff and do not give in to straightening, soaking does not help. Give good advice on what to do with it in order to restore the mobility of the joints.

- after 3 weeks of soaking in formalin or !water!?
- and how long should you keep it in acidic water?

the network writes about the neutralization of formalin with hydrogen peroxide or ammonia (but it seems to be suitable for formaldehyde vapors), I'll try...

3 weeks usually, then in extra conditions, a thermal container-the time limit-for the acquisition of plasticity, but not the fact that everything will go..Again, I, in my case, had gasoline, like morilovo, and animals-tropical grasshoppers and locusts, size under 6.5 cm..The hunters confessed, by the way-to weasel, and even more so to E.you can't buy acetate everywhere..Even after injecting with ammonia, for those who are used to spreading, it is necessary to indicate what is littered,I just sing a song to people who are spreading material from someone who is not clear..

boil a little in weak organic acids such as citric - time is determined by the degree of hardness-so I restored the first carbuses of my Caucasian ones and everything is normal-even the bags were blown out - I did not experiment with small things like Bembidion.

Igor, I'm trying to explain-in an acidic solution plus time..

the most interesting thing is that different acids act differently - acetic acid does not help. But there was no time to study all the acids on the effect on this-although the possibility was

In view of the fact that all methods are exhausted, I suggest the most risky one. For it, you will need: enzyme-containing preparations a la festal, any food acid (acetic, citric), warm clean water (preferably distilled, but some aqua-mineral without gas is also suitable), a plastic container (2 pcs), tweezers and optionally a glass of good whiskey.

First, we will prepare a slightly acidic solution (weak strength can be checked organoleptically). Then we will introduce a crushed tablet of enzymes into it (you can use half a tablet per glass). It is advisable to keep the solution at a temperature of about 30-40 degrees (the highest activity of enzymes, but not necessarily). We pour the solution into a plastic container, if not already, and heat the corpse there. Taking a glass of whiskey in one hand (you can sip from it while waiting), we periodically check the beetle's members for mobility with tweezers. As soon as they begin to move freely, it is advisable to remove the beetle and wash it in clean water (second container). Attention: the extended exposure time (distracted and forgotten) turns the beetle into an incredibly fascinating constructor (archaeologists did not dream of).

To do this, you will need:... a nice glass of whiskey.

Can I replace whiskey with cognac? The bug won't get hurt?

I tried to boil a couple of minutes in a lemon juice solution. the mobility of the joints has increased, but the elasticity has remained the same, that is, the amplitude has increased and the legs do not break, but return to the previous position. With difficulty, I straightened it out normally, but it was not possible to open the mandibles.
Thank you all for your advice.

I tested this case on the carabus coriaceus.

alaruhin, on the following beetles I will try according to your scheme

Better vodka: it is free of foreign impurities

Better vodka: it is free of foreign impurities

I had to use this nyashku. Protects against rotting of the beetles put on razmochku.

Did someone have to spread the beetles upside down? I mean, on my back. I mean, beetles laid on your back? Two evenings I suffered with Colobicus hirtus, it is not possible to fix all the legs at the same time. Finally, I turned him over on his back, the front and middle ones quickly straightened out and held on, the rear ones were fixed with two 00 pins. I think to extend this method to other trifles.

who uses what kind of glue for gluing wing breaks and gluing wing parts in butterflies?

Tell me how to straighten the bear

Tell me, please, how to spread the spider for photographing? If I take a live spider, kill it with boiling water, then when it is removed from the water, it dries quite quickly and when it dries, as I understand it, the pressure in the limbs decreases, which is why they all bend under the spider. Is there any way to spread and fix the spider on something for a short time (for 5-10 minutes)?

who uses what kind of glue for gluing wing breaks and gluing wing parts in butterflies?

Usually, without showing off, everyone uses PVA, but there is supposedly a special ento-glue, I didn't try it myself and didn't buy it (probably expensive).

Tell me how to straighten the bear

Like an ordinary beetle. And what are the difficulties with the bear?

Good day!
Can you tell a beginner why many butterflies have very strong wings after unfolding? And immediately when removed from the straightener.
Raskravilki good, the wings are completely covered with tracing paper when straightening...

I would really appreciate your advice...

My method before you remove the butterfly from the straightener I do the following I put it in the oven preheated degrees 100 120 or 2 position of the comforter for 10 minutes after I turn it off and everything is not put in the oven fresh material just dried.On a baking sheet I put a cardboard box so that the foam does not meltIt also happens that the wings do not fall much I do the following.The half of the wing that is lowered is held above the steam for about a minute and fixed on the straighteners.There are a lot of butterflies in the collections, especially nocturnal ones like straightened whiskers in vain.Here, too, boiling water and an ordinary brush cometo the rescue.Try

OK, thanks, I'll try. And why does this happen to the wings at all?

When drying, the remaining moisture evaporates, which is why the wings lead.I also recommend using the tracing paper site. glass well this is for lyubitelya

If the humidity is stable-for example, in winter when heating-nothing leads.But the material of summer straightening, without stable dryness in the room, requires a roasting cabinet or oven, before removing tracing paper and needles.Unpressurized boxes will also be dampened later..

People wonder - and with the passage of time, where do people disappear from the forum?
The answer in my opinion is obvious - they simply do not find something new and useful for themselves in collecting, studying and presenting material on insects on the forum. Young people come with absolutely the same questions, innovations and" rakes " that we once stepped on at the dawn of our foggy youth...

That's for sure. Let the youngsters frolic.

Colleagues, please give us some advice! How do you spread dragonflies and erect wings? Do you spread your wings on only one side in straight-winged birds? Thanks!

On such questions, Vasily, the answer can be found easily on your own and on our forum (once again: You would get acquainted with its structure), and just through Google.

Don't worry - everything will work out for you.

Dmitry, thank you for your advice and support!

How do you spread dragonflies?

Returning to the previously raised question... I still can't overcome the symptoms of" leading " the wings when drying. Oddly enough, but this is manifested only when straightening the "soaked" dry material, there are no problems when straightening the fresh one. Which way to go next? Where am I doing something wrong?

undelivery instantiations

yeah... Thanks! I had the same idea. And how to determine what is soaked well?

Tell me how to straighten the bear

I tried it once. cut the abdomen, pull out the insides, treat with 96% alcohol, clog with cotton wool (you can also moisten with alcohol) and spread it out. in the photo in the center 2 pcs

I don't know exactly. but the mobility of the wings should be like that of a freshly dead moth

OK, thanks, I'll try again. Just a little experience with dry material. But, I hope, practice will overcome everything))

Maybe someone will need it https://www.youtube.com/results?search_quer...utterfly&page=1

Tell me how to straighten the bear

in general, the bear is a kind of straight-winged, if it is spread according to the rules, then you need to spread your wings only on one side, but again, because it is quite unusual in shape, I spread all the wings

I want to brag. A friend at the furniture factory sawed out the blanks, I assembled them myself. the straightener turned out wonderful. the upper linings are replaceable - in construction plastic is some kind of soft porous.
