External Morphology and Development of the Hawk Moth, Macroglossum Belis (Linnaeus) (Lepidoptera : Sphingidae)
The common hawk moth Macroglossum belis( Lepidoptera : Sphingidae) wasstudied under laboratory conditions as well as in the field. Morphology of hawk moth, the egg, larval instars, prepupa, pupa, and adults was described and illustrated in this paper.Developmental characteristics of each life stage are described. In an experiments in with larvae were reared with noni leaves, Morindacitrifolia L. (Rubiaceae). Males and females were fed with 30% of honey solution. The female hawk moth laid 65-94 eggs/insect. Eggs were deposited singly on the underside or upperside of noni foliage. The egg incubation period was averaged3.26 days. The mean duration time of five larval instars of hawk moth was 1.90, 1.69, 1.45, 1.80 and 3.81 days, respectively. The total larval period including prepupal stage was 12.36 days. The pupal stage lasted 10.65 days. The longevity of males and female was 9.00 and 9.80 days, respectively.The mean head capsule width for the instar 1-5 was 0.61, 0.97, 1.44, 2.10 and 3.49 mm, respectively. The larval caudal horn lengths were 1.45, 2.46, 4.44, 7.06 and 8.29 mm, respectively.
