Acherontia lachesis, commonly known as Greater death's head hawkmoth, is a large (up to 13 cm wingspan) Sphingid moth found in India, Sri Lanka and much of the Oriental region, one of the three species of Death's-head Hawkmoth, also known as the Bee Robber. It is nocturnal, and very fond of honey; they can mimic the scent of honey bees so that they can enter a hive unharmed to get honey. Their tongue, which is stout and very strong, enables them to pierce the wax cells and suck the honey out. This species occurs throughout almost the entire Oriental region, from India, Pakistan and Nepal to the Philippines, and from southern Japan and the southern Russian Far East to Indonesia, where it attacks colonies of several different honey bee species. It has recently become established on the Hawaiian Islands.[1]

Description[edit]

A. lachesis is larger and much larger than Acherontia styx. The segmental bands and grey stripe occupying so much of the abdomen that only small patches of yellow are left. Hind wing with a large black patch at the base. The medial and post-medial bands so broad that only narrow bands of the yellow remain. Ventral side of abdomen is banded with black and wings banded with black and with a spot in the cell of each. Larva differs from A. styx in having blue streaks above the yellow ones; before pupating it turns brown and the oblique streaks disappear.[2]

Development[edit]

Eggs are laid on a variety of hostplants, belonging to the families Solanaceae, Verbenaceae, Fabaceae, Oleaceae, and Bignoniaceae, among others. Mature larvae can attain 125mm long, and occur in green, yellow, and brownish grey color forms (most commonly grey), with oblique body stripes and a prickly tail horn that is curled at the extreme tip.[3] When molested the caterpillar throws the head and anterior segments of the body from side to side, at the same time making a rapidly repeated clicking noise, which appears to be produced by the mandibles. The larva pupates by pushing its head into the earth, burying itself, and making an ovoid chamber about 15 cm below the surface in which it sheds its skin.[4]

Subspecies[edit]

Ecology[edit]

The moth rests with the wings folded penthouse-wise, where the abdomen completely covered. When disturbed, it body raises from the surface on which it is sitting, and partially opening and raising the wings, and emitting a squealing note. Notable predators are mostly the parasitoids such as Amblyjoppa cognatoria, Quandrus pepsoides, and Drino atropivora.[1]

Host plants[edit]

In their distribution countries, caterpillars are found on variety of plants such as Jasminum, Solanum tuberosum, Nicotiana tabacum, Tectona grandis, Datura, Ipomoea batatas, Clerodendrum kaempferi, Erythrina speciosa, Clerodendrum quadriloculare, Lantana camara, Sesamum indicum, Solanum melongena, Solanum verbascifolium, Stachytarpheta indica, Tithonia diversifolia, Solanum torvum, Spathodea campanulata, Vitex pinnata, Psilogramma menophron and Clerodendrum inerme.[1]
