Papilio maackii (Larvae)
It was feeding on it's food, Phellodendron amurensis, Zanthoxylum ailanthoides and Phellodendron amurense. When threatened, it puts out smelly antannae from it's head. It smelled like rotten food + rotten hard broiled egg.
Lives around Japan, China, and Korea, which are Taiga settings.
