'The Sphingidae' is a family of moths ('Lepidoptera'), commonly known as hawk moths. It includes about 1,450 species. It is best represented in the tropics, but species are found in every region. They are moderate to large in size and are distinguished among moths for their rapid, sustained flying ability. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802.

Some hawk moths, such as the hummingbird hawk-moth or the white-lined sphinx, hover in midair while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds.

Sphingids are some of the faster flying insects; some are capable of flying at over 5.3 m/s (12 miles per hour). They have wingspans from 4 to over 10 cm (3.9 in).
