Far Eastern flora: a brief excursion for non-native entomologists

I would like to offer dear entomologists a short excursion into the flora of the Russian Far East. This makes a certain difference when you want to find the eggs or larvae of a certain insect species, knowing what they live on, but not knowing what that plant looks like. If you find this useful for entomologists, I'll continue. So far, I limit myself to two types.

Mongolian oak
many butterflies, beetles, and cicadas are associated with it. For example, spotted marshmallows (Japonica saepestriata) and yellow marshmallows (J. lutea), Gerbathodes paupera, the famous barbel Massicus raddeib, and many others.
Scalloped oak
a more rare type of oak, but in the Khasansky district it is common on the southern slopes. It is associated with some relatively rare marshmallows, such as Japonica adusta and Favonius ultramarinus.

Thank you so much for the information. Really very useful, although I do not know if I will get to Primorsky Krai when

I propose to expand the topic and envy and European species of trees and insects with a description of their habitat, location in specific places (for example, barbel XXX-found on the bark in the lower part of the trunk, in such and such a month, you can detect by eaten leaves and characteristic marks on the bark) Something like that, thank you.

Oh, and also, Juglans, please don't scare me like that anymore, otherwise I go to the ssydka, and it says - Welcome, RippeR.... I almost peed my pants - where did the message to me come from on that page, I really thought that someone left a message for me there

Awesome! Swallowtail caterpillar on a legume plant... Yeah, fantastic...

Although anything can happen in nature. For example, the caterpillars of the Maak tail-bearer feed on Amur velvet, and where it is not present - on fluffy ash. But the whole joke is that Maak's tail-bearers are also found where these plants simply do not exist! That is, it is significantly north of the northern limit of the range of these Rutaceae. And at the same time, sometimes the number of tail-bearers there is large, it occurs regularly and, most importantly, at the beginning of summer, the specimens there are absolutely CLEAN (i.e., the possibility of migration, especially such a large one, is completely excluded). I myself have witnessed this more than once. For example, the Maaka tail-bearer lives throughout the Verkhnebureinsky district of the Khabarovsk Territory, where velvet and ash trees are found only in the very south. And this northern district! Most likely, in such conditions, its caterpillars switch to feeding on umbrella plants. And this conclusion is also confirmed by the fact that one entomologist I know found a maaki caterpillar on snyti gornaya!!!

And it was in the mountains at the very source of the Right Bureya. And the climate there is very harsh, like in Yakutia!
Here, I expressed my opinion...

And in general, the caterpillars of the same butterfly species in different regions can eat different plants. Another example about sailboats. In the Khabarovsk Territory and the EAO, the caterpillars of the tail-bearing xuthus (Sinoprinceps xuthus) live almost exclusively on the downy ash tree, and on the Amur velvet I found its caterpillars only three times. At the same time, I have been observing this species for 8 years, and a lot of caterpillars of this species from these regions have passed through my hands, i.e. the purity of the experiment is observed. But according to the stories of seaside entomologists, to the south, in Primorye, this species almost exclusively feeds on Amur velvet, and on ash it is not. It seems that the regions are similar, but no!..
