Collecting insects in batches

There is one scientist - I know one personally-who says that for me quality is absolute nonsense. This is how it relates to the collection. It's all haphazard.
I think (in full agreement with previous speakers) that an integral part of an entomologist is accuracy. And hence the more or less good condition of the collection. And instances. People who do not look at the quality at all - these and good copies will ruin.
There are two sides to this coin.
1. Philately - when the butterfly should be super-luxury, and nacha it does not exist. I still remember the story when the allegedly burnt eversmanni was tinted with red spots!
2. Complete carelessness to the material. It's all gone awry. Genitals in pill containers, labels written "for yourself" (Ivanovka, Petrovka, etc.)
If the goal of the collection is scientific work , then you should not neglect bad copies, but also strive for maximum quality.

Golden words!!!

But for throwing out the material, I would be excommunicated from entomology for life!
Killed - use it! Or give it to someone who needs it!

If you want, you will find someone to give it to. Even those that seemed to have fallen into the crown of Cetonia aurata in sprouts.

If an insect is rare and valuable for science, then it should definitely be in the collection IN ANY FORM, but ALWAYS with a label! It is quite usual that rare insects already in nature can have a substandard appearance and what is it worth taking!?? Then there is absolutely no need to engage in faunistics, for example - not only can some insect species be known from a particular territory in a single instance, but they can also be in a very shabby form (for example, diaries (especially large species) at the end of summer are quite common raisins on the wings as a result of bird attacks.

Collectible collections of insects should certainly be well spread out and labelled!!! It is extremely rare for "specialists" to keep a collection in an ugly state, and even prick the material on safety pins-incredible!?? But, a fact!! Here collectors are mostly big aesthetes and they (like prvilo) will not take a damaged insect in their collection.

Over the years, aesthetics (in particular, the perfection of straightening, and the quality of the material) sometimes have to make room. I had to quickly identify my own snappers (the benefit is not much - 90 copies). All the types had to be removed mostly from the mattresses and immediately glued to the dies (there was simply no time for straightening). I don't know when my hands will reach the straightening point. In the museum where I work, you need to arrange more than 10,000 copies of bees - if at least one copy has wings spread or even legs spread, as we like to do, not one. At first, I mentally and aloud reproached such mountain collectors. And now I just understand that they were not up to it. And when the bees are in rows (in collections where straightening is lame, symmetry plays an important role) , nothing even looks good. In general, I gradually degrade into an average person in the field of quality and distribution. But still, I'm all for quality, if only there was time.

Interestingly, at the request of Sergey Shibaev (the largest expert on bees and wasps-spangles of the Volga region), I also spread the previously captured bees according to all the canons. But, he begged - don't spread it out! Using the following arguments:
1. Straightened eardrums take up TOO much space (do not forget that they are also desirable series of views from one point!!) in boxes.
2. Only in some genera, you need to spread the wings and legs a little (for the convenience of determining venation, etc.).
3. It is important that the bees do not stick together the pubescence - that is, do not overdo it in the stain and immediately after extracting them from it, prick them (valuable specimens) and in the" mass " even in the fields, put them on cotton mattresses. In entomology,
only with experience comes skill!!!
But, os-blestyanok because of their meager size, I still straighten, they are painfully good in a straightened form!

It is not uncommon for me (recently) to have to determine the collections of lepidoptera spread out so carelessly that I give up-I have absolutely no desire to work with such material... How many times have I told these collectors - "In entomology, a rush is needed only when collecting certain insects"! And the " who " is still there...

I agree! Although I do beetles, but I also take glitters. Can you take a look at my three? Here:

I am at the request of Sergey Shibaev ...... also straightened out according to all the canons. But, he begged - don't spread it out!

So if he asked for it, then what did he ask for?

It is extremely rare for "specialists" to keep a collection in an ugly state, and even prick the material on safety pins-incredible!?? But, a fact!!

I wonder if the pin is fastened with this "fact"? And how exactly is the insect attached to it (I give an image of a safety pin just in case)?

As for me, the accuracy of labeling and the "interest" of the material is important, and let the owner of that collection worry about the layout.

So the genitals are better digested in luxuriously straightened specimens...

Come on, "yernichat" - You perfectly understood what kind of pin I'm talking about...

yes, and they pin the material on safety pins-incredible!??

Ah, duc, is that what you meant ?
And why did such pins become "English"?

Apparently this stuff was meant. "Clerical" in my opinion colloquially they are called?
There's a whole package lying around at home. Not only for tattoos, but even for straightening them can not be used!!! Even prick the dies on them is a great sin (rust).
Here they are:

Yes, we use these pins (for reasons of poverty) for students in the field practice (no one currently finances entomological pins). The metal on them has recently become so rubbish - it rushes at times, just from humidity...

Yes, here's another thing I've encountered recently-I bought a few years ago Moscow PVA glue in a jar, well, as I usually did before, I used it for gluing foam and plastic into boxes - I dried it on the battery until it was completely dry. Then I put the straightened glass girls there and sent them to Gorbunov. Two weeks later, he opened and was blown away - all Czech Morpho pins (in varnish!) completely rusted!??? I had to change to Japanese ones made of white metal. And the box was dried for a month...

And I have been using polyurethane foam glued to the "Moment"for some time. I also use it on "dies". Very satisfied.

And then how to peel off the dies, if necessary?

There was a time when I used to prick butterflies with safety pins, too. There were no others. Over time, I transplanted them to entomological ones. But not all of them. Crucify me?

I think that many people did this, including me

I think many people have done this, including me

Yeah, yeah

Yes, of course, everyone did this "on bezrybye" (and I too), but now we need to abandon this vicious practice (since the choice has appeared).

Do you speak bezrybye?
Here is the butterfly of a Spanish entomologist on a strange, short, obviously not entomological pin. It is dated 1994. And he's got them all pinned up like that. At least from what I've seen.

Well, however, not everyone did this, but, let's say, many. Those who live in Moscow, the Moscow region and nearby regions (like me, for example) did not have problems with Soviet entomological pins if they were willing and not lazy (pins were freely available in Moscow - this topic has been repeatedly discussed and this fact is generally recognized on the forum). Interruptions began in the early 90's, when the Union collapsed, and the Yeltsin mess began. And this period was relatively not so long and ended when the new order settled down and there was access to foreign bins. But today to prick the material on pins "with an eye", as if to put it mildly... Unsightly, impractical, and unprofessional...

"Dies" in this case is a conditional name. These are pieces of PPE, impaled on an entomological pin, on which, in turn, a micro is pinned for a minute. At the "Moment", only the PPE bottom is pasted. And there is also a PPE with a sticky layer, sealed with a film. We remove the film and glue it. On the" dies " of such PPE, however, is no longer suitable.

Oh, so you're talking about butterflies... And we are with Bad Den (om) about beetles...

Well, I'm talking about beetles (though I won't prick butterflies on them (these pins)).

In Moscow, there were almost never any problems with purchasing entomological pins.Except that in the first half of the 90s there were difficulties.The Ivanovo Region is another matter.On the contrary,it almost never had entomological pins as such.Is that IVSu (Ivanovo State University). the university) receives them from Moscow for classes at the Department of Biology,and even then in very limited quantities.This channel is closed to me,as I am a student of another university.The only alternative for me today is the pins of the Entomon online store.True, the prices there are you know what size, sometimes the hair stands on end from their prices.And the cost of delivery from Moscow to Ivanov is rather high. But what to do, you have to buy.There is no other way out yet.
I often have serious interruptions in my money supply,and I don't have enough money to buy Entomone pins.We have to use ordinary tailors.I know it's bad,I've seen people talk about tailor's pins here, but if you don't have entomological pins, you sometimes have to use them.
But I'm still optimistic about the future.Maybe there will come a time when buying entomological pins at a more or less affordable price in Ivanovo will not be a problem.

If entomological pins become cheaper , it will only be at the expense of quality!

And modern entomo. pins are only getting more expensive and the worst thing is that they have become very lousy-bend!

Vasily, what company and how much? In recent years, we have been buying wholesale in Voronezh (Sphinx), the quality has become terrible, the Chinese have begun to fake them. There were no complaints about the old Morphos - but where can I buy them now? Japanese and German VERSIONS are VERY expensive! I live on old stocks. Rarities edit on Austrian and German, butterflies, beetles and wasps-spangles on Morpho. And everything else is based on the remnants of Soviet times...

Sphinx, of course, and others are now not found in my opinion, but at a price much cheaper than similar ones in Entomon. I'll try again.

And I use fine sewing needles when I'm not in the pulpit. However, my objects are usually large

I saw piles of mattresses with ground beetles and other insects drowned in hunting glasses (1 liter) at one entomologist in the reserve. It looks (and the ambergris is still...) all just awful... That's where insects are collected in "series" and usually through "one place" - such is the "hard and thankless" work of people...

I believe that insects should be caught as much as necessary for work, and at the same time not harm the population of this species. And it may turn out that these 100 beetles in your collection were the last representatives of this species.

And it may turn out that these 100 beetles in your collection were the last representatives of this species.

This is not the worst option. And how many species that never left a trace in museum collections were lost during logging in the Brazilian jungle?

Of course, an entomologist collecting beetles once will not destroy them as much as they die during deforestation, all sorts of environmental disasters, etc. But I still think that if an insect is rare, it is not necessary to make it even rarer and catch 50-100 individuals. Take better 20 and you will have enough in the collection and will be exchanged.

if the insect is rare don't make it even rarer

When they say that "an insect is rare", it does not mean that there are few insects of this species, but that an insect of this species is rarely found by collectors.
The reason for the "rarity" of certain insects is not a small number, but a secretive way of life.
There are also special cases of" rarity "due to the locality of the species 'population, as well as" rare " migrant insects.

And I use fine sewing needles when I'm not in the pulpit. However, my objects are usually large

There are also sewing pins with a metal ball, very similar to entomological ones. Stainless steel. Only shorter and no thin ones. For most insects - quite! Sold in sewing departments.
