Methods of catching beetles...

Necrocephalus:
Ah kakraz for itself consider all kinds of serious, except quite perishing frequent insects tipo soldatika, koloradskogo, myagkotelok ordinary.. I collect all of them with great pleasure and also prick them, the dies are not very attractive, although I have to put a small change.
By the way, you shouldn't be talking so much about leistus - they are one of my favorite ground beetles-I caught them for the first time last year, I was very happy, this year there is still 1 new species

KDG:
Please specify - at what distance the cloth should lie and how far it should extend from the tree, at what time of day to try, in the morning, when insects are still slow or at any time (and even they can fly away without waiting for the fall on the canvas), dry and semi-dry branches should belong to live trees or you can shake off and dry trees and saplings? That's all, thanks for the info, I'll definitely try out the method. and the last question - where was alpina shaken off? And then we once caught them, but for 60 years nothing is known about them, maybe they are extinct..

2 RippeR: I myself am not at all a fan of dies - I think that the beetle looks much more aesthetically pleasing on a pin. But after ruining a couple of leistuses (which, by the way, I also like) trying to put them on my pin, I decided that it was time to buy some dies - and there was already a lot of small stuff on the mattresses.

On what scattering the rag is absolutely unimportant, it is important that when it is placed under low branches, the plant does not worry too much. Dimensions - the bigger the better. I use 2. 5x2. 5 m. The time of day is also not particularly important (although I haven't tried it at night), barbels fall on the sheets, as a rule, they sit quietly and try to run away only if they are additionally kicked. Weevils, antribids, and pretenders, too. you can shake off both completely shrunken bushes and trees, and partially. Rosalia caught in Abkhazia in the Musser Nature Reserve. Still well caught in Azerbaijan.

I have various barbels (mainly small ones, of course, leptures in such cases) that sat down quite well in window traps near the planted trees. Only I didn't make them out of glass, but out of polyethylene... I hung it next to the podsochennym site, no bait-as a fixative-2% formalin...

what do you mean connected trees? The ones with the juice flowing out of them?

Necrocephalus:
dies are needed, but not at all.. change on the dies and glue myself. You can also put dorcash on the dies, since the latter are difficult to pierce without hitting the hips, which is why the hind leg is lifted up.. or average..

RippeR, tell me, who are the Dorkashi ? Dorcus's or what?

As far as I understand it, pruned trees are trees with deliberately injured bark, so that the sap stands out, attracting insects.

Pour out the formalin and forget it like a bad dream. Now propylene glycol is used as a fixative.
The surface of window traps is treated with pyrethroid (insecticide), the beetle will touch the surface and immediately enter the tray!

So like propylene glycol is normal glycerin? Does it have antiseptic properties? Can you tell me how much of it is used as a fixative (I don't think it's undiluted)?

For example, glycerol is a triatomic alcohol (3 OH groups), and propylene glycol contains 2 OH groups

Exactly... Oh, then it's much more difficult to get it - I already dreamed about how I would get a couple of dozen bottles of cheap and affordable glycerin in the pharmacy for the summer
