Most likely this caterpillar no red tail, and it is not yellow. In my opinion, this is the caterpillar Calliteara pseudabietis Butler, 1885.
I, too, in the archive the same copper-butterfly is not defined from Sakhalin. She found that in Sakhalin only Celastrina ladonides d'Orza, 1869 and copper-butterfly seaside
[sachalinensis Esaki, 1922]. The first is not suitable, but the second?
She found that the butterfly pupae NYMPHALIS ANTIOPA two claws on the head.
I lived in the area 3 years. And what kind of tree on which a butterfly?
Caligo eurilochus (Cramer, ) Where Vladivostok these beauties?
The genus Caligo. Perhaps, Caligo memnon.
Twin white spots say it Acronicta rumicis strelchatka oxalic or am I wrong?

I read that in the Primorye Territory, too, periodic outbreaks of gypsy moth and newspapers cry about his importation. Perhaps and Sakhalin. Friends, tell me, who have an electronic version to the insects of the Russian Far East is 5 and the catalog of Lepidoptera (Lepidoptera) of Russia. Ed. SY Sinev.
