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

 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.

, and others. The larvae are stout with a posterior horn, as is typical of larvae of the Sphingidae. Most sphingid larvae however, have fairly smooth posterior horns, possibly with a simple curve, either upward or downward. In contrast, Acherontia species and certain relatives bear a posterior horn embossed with round projections about the thicker part. The horn itself bends downwards near the base, but curls upwards towards the tip.

The newly-hatched larva starts out a light shade of green but darkens after feeding, with yellow stripes diagonally on the sides. In the second instar

, it has thorn-like horns on the back. In the third instar, purple or blue edging develops on the yellow stripes and the tail horn turns from black to yellow. In the final instar, the thorns disappear and the larva may adopt one of three color morphs: green, brown, or yellow. Larvae do not move much, and will click their mandibles or even bite if threatened, though the bite is effectivly harmless to the human skin. The larva grows to about 120–130 mm, and pupates in an underground chamber. The pupa is smooth and glossy with the proboscis fused to the body, as in most Lepidoptera.

Folklore

In spite of the fact that Acherontia atropos is perfectly harmless except as a minor pest to crops and to beehives, the fancied skull pattern has burdened the moth with a negative reputation, such as associations with the supernatural and evil. There are numerous superstition
