Окрестности г. Кирово-Чепецка Кировской области. 30 июня.
Определил как Hemaris fuciformis. Но есть в регионе очень похожий вид Hemaris tityus, имаго которого пока не встречал, в отличие от первого. Вопрос - можно ли различить гусеницы этих видов и если да, то по каким признакам?

In my opinion, this is tityus, in fuciformis the "horn" is normally longer and slightly curved downwards in the second half, and there is a more or less pronounced light edging along the anterior edge of the first thoracic segment. In your photo, the horn is relatively short and straight, and there is no edging.

There are slight differences in the color scheme.
Here are the links:
Hemaris fuciformis
Hemaris tityus

Thanks! I looked at a lot of pictures of these caterpillars on the Web. You can agree with the length and shape of the "horn". Fuciformis may not have edging. Perhaps this also depends on the age of the caterpillar. Only inference will give an unambiguous answer. I'll sign it as Hemaris tityus and search for imago.

Why are you so attached to Sinev, he has a lot of things even for the regions of the Central European part, but this is a landmark, and not a dogma in the last instance. This is definitely not Euroctis similis. Euroctis piperita, indicated in the same Blue for the Lower Amur region, is found in Japan, nothing prevents it from being on Sakhalin.

Thank you so much for the clarification, this year I accidentally photographed everything that came across and I can't believe that someone didn't see it. Then another question, but on the sawflies, I can't find anywhere what kind of sawfly it is.
