Burstcows, where do they go?

is it possible to make a trap for goldsmiths

Window traps on forage plants will save the father of Russian democracy.

Now you can learn more about the production of so-called traps and where exactly to put them, preferably with drawings of the trap, and then according to the descriptions never dahaodit..almost..

In my Ruzsky district, gas was passed through the forest more than once. Well, of course, a lot of trees were damaged. And here I observed such a thing: on the trunk of a damaged aspen tree (like there was aspen)There were 20 pieces of Poecilonota variolosa and 5 pieces of Agrilus biguttatus. It was beautiful . I also caught Trachys sp. on the linden leaves (they were sitting on the lowest branches). Ancylocheira rusica poked on the trunk of a dead spruce.

 
I wonder if it is possible to make a trap for goldsmiths, which is very doubtful to me (I can't imagine how and I don't know if anyone did..)

I think that Shoffer is right - from what is available for an amateur, these are only window traps. You can put them near deliberately damaged trees (if your conscience allows you to destroy the tree for a couple of beetles), or near trees that you think are suitable for settling with gold leafs.

And theoretically, if you have the money and brains, you can, in my opinion, build such special traps for goldsmiths, in which they will climb more willingly than on fodder trees. It is important to find out what feeling they are guided by when choosing a tree to populate. If this is a chemical sense , then you can concentrate the attracting substance ( in the manner of pheromone traps for bark beetles, etc.) in the trap and just occasionally remove rarities from it.

In my opinion, in the simplest version, any window trap is a relatively wide and shallow container, in which a simple window glass of the appropriate size is immersed at one edge (or a piece of transparent plastic film stretched over the frame, but this option raises doubts for me). And then-variations-that is, how you fix the glass, at what height above the ground you set the trap (respectively, what and how you fix it there), what you pour into the container for fixing-it depends on your capabilities, both material and intellectual .
And where exactly to put it-it depends on what you want to catch. If zlatok - then, for example, it can be placed among the freshly sawn logs illuminated by the sun during the day. Or near a clump of ringed aspen. Or near masonry oak firewood

Personally, I think that fans of goldfinches (as well as barbels, nutcrackers) need to master the techniques of removing imagos from larvae. The adult sometimes lives for several weeks, does not land on flowers, does not fly to the light, and the larva develops for 1-5 years - so who is easier to find? By the way, I literally went to Capnodis for 3 years, and only then saw them.

Necrocephalus:
That's why I want to see the picture, I don't really understand what it is
And of course what is still there to put. You say, depending on the material possibilities, should I put a piece of Versace shirt there?

"and only then saw them"
Where, how and when?

"Or near a clump of ringed aspen"
This is also not really understood..

RippeR, if you insist so much, I will not even post a picture, but a photo It was not made by me, but taken from the Zinovsky site, where it goes as an illustration to the story of G. I. Yuferev "In search of leiodid beetles". By the way, I recommend reading it - there is a lot of information about window traps (the specifics of catching leiodids are such), and it's just very interesting
You don't need to put anything in the window traps - you need to pour it there, and what you pour there depends exactly on your capabilities, including material ones - whether formalin, propylene glycol, or just water... Given that such traps have very decent dimensions (accordingly, the volume of liquid to be poured will be considerable), they are usually placed more than one piece at a time, plus they have the insidious property of falling and spilling (or even disappearing) in the absence of the owner under the influence of external forces - You will understand exactly what the material factor has to do with take up their use. Read all the same Yuferev, he also has something on this subject.
"Near the clump of ringed aspen" - at the very bottom of the aspen trunk (or any other tree, aspen is just an example), remove a ring of bark 10 centimeters wide. In this way, you block the sap flow of the tree, and it dies, after which it becomes attractive for xylophage settlement. That's all. Put a trap (or two) nearby and occasionally catch beetles that have fallen there.

How often should I check? I would like to try it. I have at least a couple of panes of glass from the old window left. Vinegar as a fixaor will go?

And I also wonder what the principle of its use is, i.e. how do beetles get there? Are they flying, hitting the glass and falling down?
Or ride like a roller coaster, and at the bottom of the retainer..

Check depending on the retainer. The cheapest option is water with the addition of washing powder (to better drown insects), but you need just a little powder. Check in this case - the more often the better, ideally-every day.
Another fixative option is formalin, 4% r-R. Check less often, but get harder.
Naturally, after each rain, you need to watch the level of fixing fluid.
The principle of operation of the window trap-bugs fly, bump into the glass without noticing it, and fall into the fixing liquid.

And solutions by type from the topic with traps? Let's say there is a beer, wine, medic, so that someone else is attracted (the main thing is not to be homeless ) can I?

You can of course. You can even* * * t us there, maybe someone else will be attracted. The point of using retainers is not to attract, but to prevent insects from spoiling until you check the traps and get them out. The option using surfactants (as Bad Den wrote about-washing powder, detergents...) is really the cheapest, but insects will spoil very quickly, much faster than if they fell into formalin or propylene glycol. Vinegar, I think, should also extend the shelf life of insects, as well as saturated r-r NaCl. But the salt solution has a big drawback for window traps-salt increases the surface tension of water, which means it will be easier for insects to fly away. And there is no beer and "medics" - everything will spoil even faster in them than just in water.

I will also add from myself for a remarkably unusual ripper in handling the Russian language. I strongly do not recommend salt as a preservative - the white coating may not be washed off from the beetle for the rest of its life in the collection. Vinegar can seriously change the color, especially yellow, red and orange colors fade from its action instantly. I consider a sheet of transparent and pure polycarbonate to be optimal. It is lightweight, durable, and, unlike glass, lets in the ultraviolet rays that some beetles see. I also do not recommend using formalin as a fixative-the animal becomes tanned and stale, does not lend itself to straightening, the colors also fade and fade, and even the metallic luster fades. As it is not sad, the best remedy for fixing should be recognized as ethyl alcohol, for 3-4 days, burnt vodka is suitable. Another not weak option is propylene glycol, but you need to remember that if a container with propylene glycol is detected by an outsider whose pipes are burning, you can get additional bait for dead eaters, since propylene glycol has a smell that is confusingly similar to that of ethanol. In all other cases, propylene glycol is preferable, because it evaporates more slowly than ethanol, but costs less. It's great to put an open book-type hook by placing two sheets of polycarbonate at an expanded angle, holding them together at the edges.

I thought I'd left the subject of goldsmiths. I don't collect them myself, but it seems to me that they can be attracted by an alcoholic infusion of the wood of a particular tree, depending on the type of gold leaf that you need to catch. This method is also suitable for barbels.

I have several beetles collected in a trap with salt (received from one bourgeois college0-everything is fine, no plaque. Perhaps it's all about the concentration - it pours 1 kg per 10 liters of solution.

That's it... And in turmu as far as I know they won't allow you to take the collection

A note about concentration is valuable. And how often did he take prey out of the traps?

Alcohol is also not perfect - it discolors green pigments very well...

his traps hung from the tree for up to a month. moreover, he writes that the first week the catch is weak, and when it ferments...

you can try out different options.. Including with salt and propylene glycol, although I can hardly imagine how this is called in Russian and where to get it..
And polycarbonate is probably a cool thing, but I also don't know where to get it yet.

"place a book-type hook by placing two sheets of polycarbonate at an expanded angle, holding them together at the edges"

Something did not understand the value of the construction

Including with salt and propylene glycol, although I can hardly imagine what this is called in Russian and where to get it..

So it is called - propyleneglycol

Propylene glycol can be obtained in stores that sell reagents, or carefully read the contents of auto chemicals. Propylene glycol is often found in washing and cooling fluids. You can go to the hardware store and view household chemicals... there are many possibilities, but you just need to carefully study the composition of the purchased preparation on the label. But best of all, of course, clean, from the reagent store. Polycarbonate is sold most often and most easily in construction markets. It is popularly called "plexiglass". If the piece is not very large, then it is inexpensive

Polycarbonate and plexiglass (polymethylmethacrylate) are two different things, although window traps are supposed to be all the same. Polycarbonate is more expensive, but it transmits light better. Plexiglass, by the way, also passes UV.

Yes, if you dig into the nomenclature of polymers, you can dump out a dozen more names that are similar in properties to"plexiglass". You can also correctly call a car spring a helical spring, but, in fact, it's all the same...

About propylene glycol. I practiced ordinary antifreeze in Barber's traps, even diluted it (twice). The main fixing agent is ethylene glycol. It worked better than vinegar: even the spiders didn't have time to decompose in a week.
Regarding the material for the "windows": has anyone practiced celophane or other transparent films stretched over the frame? How effective are they? How much does the film vibration (from wind) affect your catches? What should be the window size, I mean the minimum level? share your experience.

Films often do not have the desired degree of transparency, slipperiness and hardness. Beetles often just sit on the film and just crawl on it. Maybe Vilgeforse will correct me and give an example of new products in the polymer industry that are close in properties to plexiglass and films, but I do not know such products.

Me too. If you can come up with an application for such transparent and rigid films , you could look for them.

It can do this: we make a frame and do not stretch anything on it and put it on. Bugs will think that there is glass or something like that, will knock on nothing and fall - the placebo effect!

2RippeR beetles have nothing to think about, so the "placebo effect" is unacceptable for them.
I believe that window traps are not quite suitable for catching goldenrods, as they are designed for small, twilight summer beetles. Well, it's rare to get "bumblebees" like dung beetles. And zlatki are very maneuverable with excellent eyesight, even if they "fly" into the glass, they will not necessarily fall into the retainer.
So sit in ambush at the windbreaks, and when you see a beetle, chase it, running through the valleys and fields... (from the Ukrainian to the Romanian border). If zlatka gets tired before you - rejoice - she is yours!!!

Zlatki fall into window traps! Of course, not so good, but they don't fall by accident. And beetles have brains, and they can think. At least some of them.

2omar
I didn't write that beetles don't have brains, but I meant what to think (in human terms) they can't, so our "Ripper" speculations are fundamentally wrong...
The only things that got caught in the window traps were gold coins-antaxias, trachyses, and nothing bigger got in...

In the Nizhny Novgorod region, my unfortunate two traps littered large pine trees...

They are very rare here, and I only found one hit by a car once... But they say that BSZ is just a fucking flyer...

Yes, I've only seen it once in the Moscow Region, too. And there-the most common beetle in June.

"If zlatka gets tired before you-rejoice - she is yours!!! "
That's not even the point of the problem.. It's easy for me to catch a gold leaf - the method of not noticing the net always worked, they, fools, never notice the canvas according to my observations. Another question is where they are sitting!? There are almost no suitable places

Usually zlatki fly to dead or dying trees (in which larvae develop). In the north, they are active during the hottest hours of the day and fly to warm trees.
Knowing from the literature which species prefers which type of wood - make a "small" clearing and sit at the rubble and wait for the zlatki to fly together. At the same time, barbels with bark beetles will "catch up".

In the Crimea, I once caught dozens of Capnodis tenebrionis and several Perotis lugubris in an abandoned garden on drying stone fruits of the genus Prunus

And Eurythirea aurata in the Southern Urals is often found in the mass on poplars, and often not on freshly felled ones, but long-dried ones with fallen bark

or rather? What do they sit on, in what places? I already know for sure that our people were sitting on an American oak tree.
