Pupation occurs in an earthen cell or loose cocoon at the soil surface. Control includes the use of a natural enemy, the braconid wasp ( Apanteles congregatus), which parasitizes the larvae. These leaf-feeding pests are green and can be 10 cm (4 inches) long. quinquemaculata), attack tomato, tobacco, and potato crops. Two economically destructive North American species, the tobacco, or southern, hornworm ( Manduca sexta) and the tomato, or northern, hornworm ( M. a Eurasian quaker moth, Agrochola lota, which has a red-edged line on. The leaf-feeding larva generally has a smooth body with a characteristic dorsal caudal horn, hence the common name hornworm. Designating the colour of blood, a ruby, a ripe tomato, etc. The proboscis of this hawk moth is long enough to reach the nectar receptacle of the orchid, which is between 20 and 35 cm (8 and 14 inches) in length. The species Xanthopan morganii praedicta, named in honour of its predicted existence by Charles Darwin and Alfred Russel Wallace, exclusively pollinates the Madagascar orchid, Angraecum sesquipedale.

The mortality strongly increased and the weight of pupa significantly decreased with the rise of density, but neither duration of larval and pupal periods, head width nor body weight of larva (except the fifth instar) differed significantly according to the density. The isolated pale green larvae showed longer duration of life, larger food intake and higher rate of oxygen consumption than the crowded dark-colored ones. The presence or absence of light not effective on the darkening. The darkening was determined by the density of the first instar. The highest degree of darkening appeared in the larvae kept under crowding conditions throughout the whole larval stage. Most of the larvae kept in isolation since the hatching were pale green, but those reared in the densities of 2 or more individuals per vessel turned brown after the first moult and, from the beginning of the fourth instar, changed into dark brown or green with broad brown stripe dorsomesally. The larvae were reared at different densities of 1-5 individuals/plastic vessel, 12×3cm, at about 30☌. The experiment was carried out in order to analyse the effect of population density during the larval period on the larval coloration and development. It is well known that the larvae exhibit color variation in the field. The female moth lays eggs singly on the underside of leaves.
There are 4-5 generations in a year in Kyoto. The larger pellucid hawk moth is a common pest of cape jasmine, Gardenia jasminoides ELLIS in Japan.
