Herbivory by the death's head hawkmoth, <i>Acherontia lachesis</i> (F.) (Lepidoptera: Sphingidae), on tobacco was recorded in Oyama, Tochigi Prefecture. The larvae attacked leaves in the lower to middle portion of the plants. They consumed a large area of leaf except the mid-rib. Typically, one larva consumed several leaves from a few adjacent plants. Observation in a 570 m² tobacco field (1,110 plants; var. Tsukuba 1), where no pesticides had been applied since transplanting, revealed that 80 plants (7.2%) were injured by final instar larvae of this species. The overall decrease in yield is estimated to be less than 1% by defoliation due to this pest.
