The name death's-head hawkmoth refers to any one of the three moth species of the genus Acherontia (Acherontia atropos, Acherontia styx and Acherontia lachesis). The former species is found primarily in Europe, the latter two are Asian; most uses of the common name refer to the European species. These moths are easily distinguishable by the vaguely human skull-shaped pattern of markings on the thorax. All three species are fairly similar in size, coloration, and life cycle.
These moths have several unusual features. All three species have the ability to emit a loud chirp if irritated. The sound is produced by inhaling and expelling air, which vibrates the epipharynx like an accordion, often accompanied by flashing of the brightly colored abdomen in a further attempt to deter predators. The chirp of the death's head hawkmoth takes approximately one-fifth of a second. A study by National Geographic found that the epipharynx was originally built to suck up honey, but was modified to produce sound.
All three species are commonly observed raiding beehives of different species of honey bee for honey; A. atropos only attacks colonies of the well-known western honey bee, Apis mellifera. They can move about in hives without being disturbed because they mimic the scent of the bees
