Theretra oldenlandiae, the impatiens hawkmoth, taro hornworm or white-banded hunter hawkmoth, is a member of the family Sphingidae. It is found in India, Sri Lanka, China, Borneo, Japan, the Philippines, Thailand, and Australia. It was described by Johan Christian Fabricius in 1775.
The species differs from Theretra lycetus in being greyish brown without pink suffusion and the two dorsal lines on the abdomen are silvery white. There are also oblique stripes on forewing and the sides of abdomen is ochreous, not golden. Hindwing with the submarginal band ochreous and narrow.
Larva is pale purplish brown. There is a yellow subdorsal line and white spots with a pale lateral line below them on the thoracic somites. Black-ringed ocelli can be seen on 4th to 10th somites, where the first two centered with blue, and posterior with purple. In the early instars, posterior ocelli are centered with crimson color with dorsal bands of yellow specks. The species is found in open lowland habitats. As the caterpillar crawls, it sweeps the tail-like horn, which is black and tipped in white, in an arc forwards and back.

GBIF citizen-science records
It is estimated from how often the White-Banded Hunter Hawkmoth is recorded against all the insects logged in Hangzhou (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
