- Distribution -
Found throughout Africa, Madagascar and most of Europe. A slightly different form, regarded by some as a separate species, is found throughout Asia.
- Derivation of Name -
The Death's head hawk moth is so called because of the skull-like pattern on the thorax. As far as the latin name is concerned, according to Pinhey (1975): "Atropos, one of the Fates, was a daughter of Nox and Erebus and was illustrated... with veiled face and a pair of scissors to cut the thread of life. This is the thoracic pattern of a mask with scissors below it. A sinister but undeserved portrait."
- Life Cycle -
o Adult: When handled the moth emits a loud squeaking sound made using the curled up proboscis. The adult moth raids bee hives for honey.
o Egg: Eggs are laid singly on leaves of a wide variety of plant species but especially on those in the potato family (Solonaceae).
o There is much varying appearance between the 1st instar and 4th instar larval (caterpillar) stages.
o Final (5th) instar larva. When disturbed, the caterpillar is able to make a clicking sound by clashing its mandibles together. The sound is evidently similar to that made by clicking the finger-nail under the thumb nail or to the sound made by an electric spark.
o Pupa: The larva buries itself in soft soil about 15 cm below the soil surface and makes an earthen cell around itself by pressing back the soil with its head. Over a period of about two weeks it forms the pupal skin and pupates. The pupal stage lasts 2-3 weeks in summer, or if it is at the end of summer, it might overwinter in this state and emerge once temperatures warm up.
