The distinct larva of tetrio sphinx is recognizable by its rugged, yellow and black striped body with a red posterior horn, while the adult transitions into a creature with shades of grey, brown, and black veiled wings. Indigenous to tropical climates, this species primarily feeds on the leaves of Apocynaceae family plants during its larval stage, and as an adult, it exhibits a promiscuous pollen-transfer behavior, which contributes to plant biodiversity by pollinating a variety of tropical flora.
