Sphingidae
![Frenulum of a male comma nephele hawk moth as seen when the fore wing is pulled back. It fits into a retinaculum on vein Sc on the ventral side of the fore wing,[7] and couples the wings in flight for efficiency.[8] In males it consists of a single, though compound bristle, while females have several compound bristles.[9] The frenulum is reduced in some Smerinthini.[8]](/uploads/202502/12/Nephele_comma_se_frenulum,_enkele_saamgestelde_borselhaar,_c5146.jpg)
The Sphingidae are a family of moths (Lepidoptera), commonly known as hawk moths, sphinx moths, and hornworms; 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.
