Are there any facts about the extinction of insects today?

In vain. Endemics are just a gift for understanding faunal and formogenesis

This is if you do it.

Yes, when considering the horons, and the list of endemics of administrative territories is really useless.

The initial question was about the fauna of Russia. And Khoronov is on it... ^^
There is no question about administrative territories. In general, endemic lists as an end in themselves are useful only for selling material.

This is if you do it.

Logically. But if you spend a long time working with a certain group (naturally, having a certain genesis under your feet), you inevitably come to questions about its evolution.

Is it true that there was a certain type of two-winged saiga antelope gadfly, which parasitized saigas and, due to a sharp decline in their numbers in a certain period, completely died out?

Again: how do you finally make sure that it is extinct? We need to check all the remaining saigas... The question you raised about the facts of the extinction of insects today does not have unambiguous answers. Insects are very small organisms, it is impossible to count them all and make a conclusion: the species is extinct or not. The topic is not serious. It is possible to speak with a sufficient degree of confidence only about the extinction of some "well-marked" species, for example, butterflies in some territory - like apollo in the Moscow region, hawthorn in England, etc. I do not see the point in continuing this "coffee grounds guessing" about the extinction of species today, but new ones are interesting facts about the "long undetection" of some species in some large territories. For example, I would be interested to know: has anyone caught Oeneis tarpeja on European territory in recent years, other than Zhiguli? Once the species was found in the Moscow region, Saratov and Volgograd regions... There is no information available in the last 30 years. I'm not sure that tarpea is still in Zhiguli.

Google mentions that In Chuvashia 31.5.95 in the kovylnaya steppe gulch, the vicinity of the village is located. Kurochkino Kozlovsky district caught one female.

I don't know about modern tarpeia... I'm more interested in the bug that lived on muskrat (damn, I don't remember the name) ecto "parasite"? He lived in the nests of muskrats and traveled in wool on the animals themselves... A different species lives on the beaver... This species has not been found on muskrats... Do they find the beetle now on small animals during trapping?? Guys, what do you know? In nature reserves??
The fact is that Olsufiev in the 20s of the last century described this beetle from near Penza, but it turned out that this species was described in Europe before him... I have a copy of this article...

Regarding muskrat - those who catch it are extremely rarely interested in its parasites. I know only one person who is capable of this, then where he works, the muskrat has not been seen for a long time - this is the Kaluga region.
regarding the satyr tarpeia-it is believed that it disappeared in V. Ukraine and Ts. Russia (in the Moscow region, recent observations, according to the dep. manuscript of Sirotkin, somewhere in the middle of the 20th century, in the Tver and Yaroslavl regions-pre-Soviet instructions). The latest data for the Volga region - Chuvashia, Ulyanovsk region and further south-we should look for the works of Lastukhin and Zolotukhin, respectively.
Here, at Lastukhin's (2007): 1995, Kozlovsky district. And from the Ulyanovsk region. I saw the collection of the first half of the 80s, and later articles should be searched in stacks, it's hardly fast.

Oeneis tarpeia lives in the vicinity of the Zhdanovsky backwater in the Kstovsky district of the Nizhny Novgorod region and at the Sormovsky cemetery in Nizhny Novgorod (on a clearing along the power line - there it is alone). Both populations are stable, observed every year.
