Manduca sexta matching flower (IMAGE) Max Planck Institute for Chemical Ecology Caption A hawk moth (Manduca sexta) uses its eight-centimeter-long proboscis to drink nectar from a flower of Nicotiana alata, a species of wild tobacco also called jasmine or winged tobacco. The nectaries are located at the very end of the long corolla tube. Proboscis and flower are perfectly matched in length.
