Acherontia atropos
''Acherontia atropos'' is the most widely known of the three species of Death's-head Hawk moth. ''Acherontia'' species are notorious mainly for a vaguely skull-shaped pattern on the thorax.
==Appearance==
''Acherontia atropos'' is a large hawk moth with a wingspan of 90–130 mm (about 3.5 to 5 inches), being the largest moth in some of the regions in which it occurs. The adult has the typical streamlined wings and body of the hawk moth family, Sphingidae. The upper wings are brown with slight yellow wavy lines; the lower wings are yellow with some wide brown waves. It rests during the day on trees or in the litter, holding the wings like a tent over the body.
The moth also has numerous other unusual features. It has the ability to emit a loud squeak if irritated. The sound is produced by expelling air from its proboscis. It often accompanies this sound with flashing its brightly marked abdomen in a further attempt to deter its predators. It is commonly observed raiding beehives for honey at night. Unlike the other species of ''Acherontia'', it only attacks colonies of the well-known Western honey bee, ''Apis mellifera''. It is attacked by guard bees at the entrance, but the thick cuticle and resistance to venom allow it to enter the hive. It is able to move about in hives unmolested because it mimics the scent of the bees.〔Moritz, RFA, WH Kirchner and RM Crewe. 1991. Chemical camouflage of the death's head hawkmoth (''Acherontia atropos'' L.) in honeybee colonies. Naturwissenschaften 78 (4): 179-182.〕
The British entomological journal ''Atropos'' takes its name from this species.
