I also already thought about making preparations on a slide, for example, leatherworm mustaches. And then it is inconvenient to look at them with binoculars : - (Are there any books on the manufacture of drugs on the Web? And then I do not know how, what and in what to do them.

In glycyrin have not been, I tendrils prepared in glycerin store.

Nebria-06.07.05. Carpathian Mountains, Ivano-Frankia region. Bystritsa River bank, by kamiushki

Nebria is similar from the subgenus Eunebria. What is the length? If so, there are two species from this subgenus in the Carpathians: N. picicornis picicornis & N. jokischi hoepfneri. I am inclined to believe that this is jokischi. This definition is a method of exclusion, I do not undertake to judge 100%. I have never seen it myself, but I have the Caucasian N. picicornis luteipes for your reference. they don't look alike. I'm going to post a photo in the topic Genus Nebria. Yes, is there any extra material?

Dzanat, I have never made micro-preparations at all : - (I am looking for literature, then I will look for a microscope and materials: -)

Yesterday I prepared some photos of how I do it. Don't put it under the slide. On the website of Zhukov there is an article ON THE METHOD OF PREPARING GENITALS IN ZHUKOV O. L. Kryzhanovsky and V. M. Yemets ENTOMOLOGICAL REVIEW, LI, 1, 1972 there is still something to see (on the website).
But you only have the tendrils, you can just put them in glycerin. I was advised to take the correction tape..? but I do not know where to get it.
Therefore, I take a strong film and make holes with a heated nail, in the hole - a drop of glycerin-there is a tendril, cover it and that's it. Glycerin dries or evaporates over time, I don't know, but if you work constantly, this won't happen smile.gif
I also glue my sawyere with PVA glue.

smile.gif but I just don't know the other one. My colleague is currently abroad, but he promised to tell me about the balm and what to buy when he arrives... I didn't read the literature frown.gif, they showed me how to dissect once, and that's all, it's not difficult. And if you have any questions, write me, I make preparations for genitals of all sorts of trifles.
Good luck.

Success.


I just cover it with balsam, which is called (in direct translation) "rubber syrup modified by the Apati method "(Gumisirup modifiziert nach Apathi). It costs a penny and is available in Germany. Covers the preparation with a uniform smooth layer. Does not mold, does not crumble. It is also water-soluble.

I dissect my abscesses into separate parts and stupidly shove them into a penicillin vial filled with glycerin. Genitals pre-boil in 10% KOH for 5 minutes, then in alcohol, then in glycerin. Next - the label on the bubble - taxon, locale. And it's been around for years. I need to look at the tendril, claw, penis or maxilla - I find the right bubble, pull out the right part with tweezers and voila... I don't want to see it.

The usual "Canadian balm", as far as I understand, is just a solution of purified rosin in xylene... Now they still use Euparal. I don't know exactly what it is, it's some kind of resin, it smells like eucalyptus. Alcohol-soluble. But they are not suitable for everything. In many cases, you can't do without Fora-Berlese liquid.
And you can also make preparations in a drop (from small creatures): a piece of transparent dense film (just so that xylene does not dissolvesmile.gif, put a flat (!) a drop of Canadian balsam, but to completely cover the preparation. Then all this is pinned on the same pin. In any case, if you don't like it, you can throw it back into xylene and redo it as you likesmile.gif

Your 2 zaitsevs and 2 ?praticoles, together with several philanthus and Siberian hoplias from Dorcadion (Hoplia ?aureola) are sitting on mattresses and waiting in the wings to go to you wink.gifSo you just need to think about how to send (train, bus or what yes how..)

Here, it seems to be the same. 13 mm.

It's definitely different.. This one is from Alpaeonebria

This nebria from Aplaeus - the width of the pronotum is greater than the width of the base of the elytra. Eunebria already has.

Considering that 2 photos with 1 name are average - not Nebria

And the third one also seems to be from Alpaeus

If it is a Patrobus (with red legs), then most likely it is a Patrobus quadricolis Miller 1868

This is some kind of Carpathian Deltomerus - the eyes are too flat and, like, the crown is covered with bristles. If the legs are pubescent on top, it's definitely one of them. And their biotope. But there doesn't seem to be much Deltomerus out there...

And where did you catch it (country)?

Here, it seems to be the same. 13 mm.
Transcarpathian region, Petros river, under the rocks by the stream. h=1700 m.

The other one, of course. I can't say anything about Alpaeus, except for Transylvanica in the Carpathians, there are three more species
There are also some nebriyas .The locale is the same. h =1450-1700 m.
1st 10 mm
2nd 12 mm
3rd 12 mm

1-looks like Boreonebria. I.e. either rufescens or heegeri
2-Deltomerus carpathicus. From Deltomerus, he is there alone
3-Another Alpaeus! Great! It remains only to recognize them smile.gif

jump.gif Definitely him! Deltomerus carpathicus (Miller, 1868).It is endemic to the Eastern Carpathians. It remains only to transfer the image to the topic "Endemics of the Carpathians".

For Mr. Ripper.

I tried to spin the photo of Miltotrogus that you provided , but I was dissatisfied with the overall result. Could you take another snapshot of this instance? It is advisable to remove in such a way that the pronotum, head (especially the platypus!)are clearly visible. and antennas (at least on one side).
Sincerely,..

C. atrata is a much smaller beetle. As for C. granulata, I have a subspecies (Stolichkan) with an extensive solid white pattern along the edge of the elytra. There is so much white that it can be mistaken for the main color of the elytrasmile.gif

31.08.2007 1:43, Victor Titov

Frantic, thank you! After your answer, I searched for Cicindela (Cicindela) granulata (Gebler, 1842) through Google, and it seems that my beetle really looks like it. By the way, there are also images of specimens with a solid light pattern along the edge of the elytra.

The body length of C. granulata is not less than 17-18 mm. Elytra are black with a matte gloss, the white pattern may not be pronounced. The elytra sculpture is quite smooth. Here you can also see the obvious graininess. Although, with such an increase, everything can be

The size of my instance is exactly the same. But the granularity of the elytra, especially from the base to the middle, is obvious. So, is it still C. granulata?

Similar to granulata. The issue with grain size is open, maybe there are such-there are several subspecies
