a family of hawk moths. They are of average and large size; the wingspan is 2 to 18 cm. They are characterized by a cigar-shaped body, narrow elongated forewings, and spindle-shaped antennae. The insects can fly with a velocity of up to 54 km/hr and “stand” in the air, sucking nectar from flowers with their long tongue while in flight. (The length of the tongue in the Madagascar hawk moth, Macrosila predicta, exceeds 25 cm.) Sphingidae caterpillars are always naked. They feed on leaves, stripping the shoots bare. There are about 1,200 species, which are found throughout the world. Most are found in the tropics; in the European part of the USSR there are 26 species, and about 40 are found in the Far East. Some members of the family Sphingidae are capable of long flights. (Daphnis nerii flies from the shores of the Black Sea to Finland.) The pupae winter in the soil. Some species are harmful to one or several closely related plants, most frequently woody plants. The pine hawk moth (Sphinx pinastri) and the eyed hawk moth (Smerinthus ocellatus) are among the harmful species in the USSR. The convolvulus hawk moth (Herse convolvuli) is useful in destroying bindweed in the southern Ukraine.
