Theretra silhetensis, the brown-banded hunter hawkmoth, is a moth of the family Sphingidae described by Francis Walker in 1856. It lives in Indo-Australia, India, Sri Lanka, Papua New Guinea, East Australia, Solomon Islands, Fiji Islands, Vanuatu Islands.
The wingspan is 60–72 mm. Not to be confused with Theretra oldenlandiae in being very much paler in color and with a white line down the center of the abdomen. The forewing has a silvery line beyond the oblique brown band. Other parts are ochreous. Larvae are exceedingly variable, from yellow green and green to brown or greyish black ones. But the commonly found color of larva is green with a reddish-brown dorsal area. There is a subdorsal paler line with equal-sized ocelli from 4th to 10th somites with green center. The horn is reddish brown as well.
Larvae have been recorded feeding on Colocasia antiquorum and Ludwigia species in southern China, Colocasia esculenta in Japan, Ludwigia repens and Boerhavia species in India and numerous other host plants from elsewhere, including Arum, Caladium, Pistia, Kochia, Ipomoea, Boerhavia, Ludwigia, Rosa and Trapa species.

With luck
About 10% of wildlife watchers report a Brown-Banded Hunter Hawkmoth sighting in Daintree National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 173rd most-seen of the 856 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Brown-Banded Hunter Hawkmoth is recorded against all the insects logged in Daintree National Park (20 verified sightings from 2019 to 2026), 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.
