Newly emerged Acherontia styx imago resting on Vitex tree trunk
I had chanced upon a pupa beneath the Vitex negundo tree in our garden on 29th August, 2010. It was dark brown and wriggled in my hands. I put it in a jar with a muslin cloth on top to allow breathing and decided to see what emerged. It looked like a Sphingid pupa and I was pleasantly surprised, when on 5th September, 2010, I discovered that a handsome Death’s-head Hawkmoth had emerged from the pupa.
I placed the adult moth on the Vitex tree trunk and photographed it. While handling it I heard it emit squeaking sounds. The light was very poor as it was early morning and I had to use the on-camera flash. After taking a few photographs, I noticed that the moth was fluttering its wings to warm its wing muscles. As I took the last photograph it flew away swiftly to the upper branches of a nearby silk cotton tree.

Acherontia styx warming up before takeoff!
This large hawkmoth, Acherontia styx belongs to the family, Sphingidae. Hawkmoths are moderate to large, stout but streamlined moths known for their rapid sustained flying ability. Some species are able to hover in midair like some hummingbirds.
Acherontia styx is a Sphingid moth found in Asia, one of the three species of Death’s-head Hawkmoths, also known as the Bee Robber. It is very fond of honey and bee keepers have reported to have found dead moths in their hives as a result of bee stings. They can mimic the scent of bees so that they can enter a hive unharmed to get honey. Their proboscis, which is stout and very strong, enables them to pierce the wax cells of the beehive and suck the honey out.
This moth is easily distinguishable from others by a vaguely skull-shaped pattern on its thorax.The adult has the typical streamlined wings and body of 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.
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.
