Sphingidae

Sphingids are a family of moths (Lepidoptera), commonly known as hawk moths, sphinx moths, and hornworms. They are easily distinguished from other moths for their fast, hovering flight (typically at flowers) and their impressive "jet-like" appearance while at rest. They have narrow wings and streamlined abdomens.They are sometimes mistaken for hummingbirds because of their appearance in flight. They have been much studied for this flight ability, especially their ability to move rapidly from side to side while hovering. It's been recorded that some Sphingiids are capable of flying at over 12 miles per hour. Their larvae are charectarized by having a distinct horn on near the rear end.
