Theretra clotho is a moth of the family Sphingidae. It is found from Sri Lanka, India (including the Andaman Islands), Nepal and Myanmar, east through China to Taiwan, South Korea and Japan, and then south-east through South East Asia as far as the Lesser Sunda Islands and Timor in Indonesia. An uncommon migrant may be found up to northern China (this range includes Theretra celata, which is sometimes treated as a valid species). The habitat consists of open forests, forest edges, orchards, plantations, wooded scrubs, suburban gardens and city parks.
