Rare species. When are they available?

Using Kakayog, you can only catch dung beetles!!!

and on itself

Or under itself....

and on your own

Well, this is only for diarrhea... but then, I read somewhere that for sloths, coprophages penetrate directly into the anus.

It seems to me that speaking about the 100% success of any kind of search, a person is a little disingenuous. There can be no such successful result in research, especially when searching for rare and locally common species, too many accidents are usually superimposed on a pre-developed plan. You can probably catch a species if the population is already known and studied, and the search for new habitats of the species is fraught with unexpected risks and unforeseen factors, but this is great, the more interesting and valuable the find will be for the researcher.

As mentioned above, rarity is a relative concept.. Even rare species come out in dozens, maybe hundreds of species, otherwise they would have become extinct. Of course, they don't all sit on the same twig. They run away, fly in different directions on their own business-search for food, partners, all sorts of nonsense. If, for example, in some not very large forest there is such a population, then what are the chances of coming across an entomologist who combs everything up and down in a fairly short time..? Naturally quite large!
The difficulty arises with other species, often not even small in number, but which lead a very hidden way of life - in anthills, in the crowns of trees, underground, etc. Especially if these species are very small.

Of course, the rarity of species is relative. The species may be rare on a regional scale, but numerous in a single point, even sometimes being dominant in the biocenosis. The task of the researcher is to find and study such "compact habitats". And then there are three questions that determine the success of the search: where, when, and how? If the researcher can predict the location and time of the search based on knowledge of the biology of the species and has an effective collection method, then the probability of success is quite high, but this is far from 100%, because it is impossible to calculate all the factors. If we are talking about commercial collection or simple replenishment of the collection, then the chances are much higher, because in such cases, new populations are usually not searched for, fishing for already known places.

the "rarity" is that it is impossible to examine everything.. After all, even in our small Moldova, we need a lot of specialists who constantly examine every meter, using all sorts of collection methods.. and this is almost impossible, since we are not multi-armed, and even worse, we are not numerous.. Currently, it is more difficult to meet an entomologist than a rare species. There is one good, but local population of entomologists-molbiol

The main problem in finding a "rare" species is knowledge of the features of biology, microstations, etc., which is usually impossible to learn from the literature, but you have to "get" it empirically. If you manage to find out some features of biology-your beetles are practically in any potentially suitable stations. (I'm responsible for the words...).
And as an example, look here:http://www.zin.ru/animalia/coleoptera/rus/poiski_5.htm (and to adjacent pages)!
