I have a similar question about the Colorado potato beetle.. how do I keep it white? I always have a "dirty" color when it dies..ugly(

I also had yellow ones.....it must be soaked in EA (ethyl acetate = "weasel") of high concentration in the stain and do not take the beetle with your hands! Chob he not "zasiralsya" and morilkoy, vyskivaesh through 10-30 minutes (better-less) and kleish-ideal! verified.
the main thing is to take it "without fright" = so that it does not start highlighting "everything that spoils it"!

yes.gif And I will also add: it is necessary to put toilet paper or blotting paper in the stain (as is generally accepted for beetles)- then all the trash will remain on her, and not on the beetle.

blotters were put in the century before last, and now large lime sawdust, which is soaked with a toxic substance

Well, with lime sawdust tension. Therefore, I put strips of toilet paper folded "accordion" in a regular stain in the cork of which corresponds to cotton wool soaked in EA and do not worry "not a gram".
P. S. For the first time I heard about sawdust, by the way: what are they better than?

I read somewhere that in order for insects to retain a close to natural green color, they need to be dried in snuff.
What can you say about this? no one tried it?

Not to dry, but to sea. I tried it. Cassida leaf beetles retain their color better than after ethyl acetate. Although still not 100%.

what about grasshoppers

02.12.2011 10:53, Victor Titov

what about grasshoppers

I've never collected grasshoppers. I guess they should be gutted anyway.

02.12.2011 13:42, Zlopastnyi Brandashmyg

As far as I know, green grasshoppers fade inevitably. The pigment is contained in the hypodermis, often (in all cases-I don't know, I didn't do biochemistry, and no one did it on a wide material!) it is a chlorophyll. Therefore, when drying/fixing, the color degrades. I have repeatedly heard about a variety of" clever techniques " for preserving color, but I have never seen a satisfactory result. On the other hand, I'm not really interested.

It is better not to gut it - after all, damage to the material, but there is a lot of fuss. After a short immersion in alcohol (several days), the material does not rot. For large animals, you can inject alcohol with a syringe into the "fleshy parts of the body", the result is the same, plus, with some skill, the abdomen stretches without any stuffing.

02.12.2011 17:46, Dmitry Vlasov

And if instead of alcohol, the abdomen is formalin???

02.12.2011 18:02, Zlopastnyi Brandashmyg

You can also use formalin, probably. Formalin is highly tannic and toxic. I burned their hands when I was a student, and I've been trying not to use them ever since.

????????????? in any specialized shop/shop "tabak" there is for all tastes, even with menthol, even with strawberries. but there is also the usual

This is not true!

Absolutely true! In Yaroslavl, at least, in specialized stores "Tobacco" is sold.

Please tell me from what material it is better to cut strips for spreading the wings of butterflies?

12.12.2011 10:35, Liparus

maybe styrofoam?

12.12.2011 11:14, Victor Titov

Please tell me from what material it is better to cut strips for spreading the wings of butterflies?

I think it is better to use a smooth (not scratching the wings) transparent material-cellophane, tracing paper, etc.

Arthur, are you kidding me? wall.gif

Recently, a lot of materials have appeared that are suitable for spreading butterflies, but based on experience , the most suitable, high-quality and inexpensive were transparent plastic files under sheet A-4, but not simple soft ones under the sheet that is inserted into the file from above - but dense and transparent ones, where the sheet is inserted into the file from the right/inside (I don't remember the company seems to be Taiwan-I specially bought it to try, and when I realized that this is what I needed, they didn't sell it anywhere - I had to order it specifically from Moscow). They were quite expensive a few years ago - but I bought a package of 100 pieces and have been using it for many years/I am happy about a successful investment of money...

As for the straighteners, someone praised the flat ones - it turned out that the flat dies are EXTREMELY convenient for straightening butterflies from the underside! When drying, they are pulled together in any way to the bottom and thus a small angle is obtained. By the way, German straighteners at an angle of 10 degrees - ours at 5 , from practice it turned out that the German angle is more reliable! natural sagging when drying the wings eats up to 5 degrees. Pedants however.

I use tracing paper strips - no problem!
Affordable and convenient.

12.12.2011 23:34, lepivin

thank
you very much and what are the files called?

13.12.2011 1:23, Aaata

Such strips are sold ready-made, for example, in the Entomon online store http://www.entomon.ru/online/goodsGroup.php?id=4 They are made of translucent parchment, of different widths, in rolls of 40 meters-enough for a long time, especially if you dream of using them again, with the reverse side.

13.12.2011 17:44, niyaz

At first, I used tracing papers, but I had to abandon them, since there is little to see from under it. I decided on thick cellophane, so far I am satisfied.

13.12.2011 18:40, vasiliy-feoktistov

Synthetic transparent of course is good for large butterflies with strong wings. But it has one disgusting quality: it has the property of accumulating static electricity and attracting the delicate wings of small butterflies. Here for small things it is better to use tracing paper and edit as it is written in the literature: "Your collection", etc. Just advise as already something constipated thanks to plastic.

Problems can be avoided if the film is not lifted, but pulled along the plane of the straightener in wink.gifthe line

14.12.2011 11:13, Penzyak

..yes, plastic for small pigeons can be problematic in terms of electrification, but if you spread it out in two separate pieces, it is tolerable. I do not advise moving "sideways" in small pigeons - small funnels form on the plastic from the bottom of the needles and they can spoil the scales on the wings. Another aspect is that if the plastic is pressed down tightly and the pins are concave with effort, then fresh specimens may simply stick the wings to the film and then when the plastic is removed, part of the wing will simply fall off or exfoliate ... Tracing paper is too delicate, muddy and impractical in my opinion...

14.12.2011 11:47, rhopalocera.com

tracing paper rules. plastic guano, its main disadvantage-does not allow air to pass through, does not allow the wings to dry evenly.

I recommend everyone a probe for straightening the wings.
At the end of it is a ball that does not pierce the wings.
I've already straightened a couple of butterflies-very convenient.

is this a dental instrument?

25.12.2011 1:24, lepivin

Yes

what else do you use? what are the tools? scissors and tweezers?

25.12.2011 9:37, vasiliy-feoktistov

Download it! And read carefully (apparently the forum is not read in any way, so once again posted the book): M. Kozlov, E. Ninburg "Your collection". Collection and production of zoological collections (manual for students). Moscow, Prosveshchenie Publ., 1971. umnik.gif All methods, tools, etc.are there. Once again the link where in Moscow you can get the equipment: http://www.entomon.ru/

Google it, maybe you'll find it. I have it as a memory from the childhood of the Soviet and cloudless remained in the original: shore.

tracing paper

02.01.2012 1:37, Aleksandr Ermakov

Also tracing paper. Several times, as an experiment, I pressed the wings of small butterflies on the straightening plate with slides. It worked, but I don't recommend it.

Hello.
Someone here said that if you do not stand the beetle in solution (Fai) before manting it on the die, then the die and the beetle will become fat.
Is this really the case?

05.01.2012 12:41, Коллекционер

For some reason, I have a lot of insects covered with fat of various orders
.
Ditiskusa I have already wiped three times and it is still covered with a layer of some oily v-va

Yes, please tell me what is the best way to wipe the beetle so that it does not get covered with fat. It can be an aciton or something else.
