Death's Head Hawkmoth Caterpillar


Hi Siraaj,
At first we were going to write back and just say that you found a species of Hawkmoth Caterpillar in the family Sphingidae, commonly called Hornworms because of the caudal horn.  When we googled Sphingidae Africa, we quickly found an image of a Death’s Head Hawkmoth Caterpillar, Acherontia atropos, on a Biodiversity of South Africa website and we feel pretty confident that is your species.  The adult moth is pictured on the movie poster of the Academy Award winning Silence of the Lambs and played a role in the narrative of that film.  Regarding the d
erivation of name , according to the Biodiversity website:  “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.'”  Excellent information and more photos can be found on the Sphingidae of the Western Palaearctic website.  The downward curve of the horn is distinctive in the mature caterpillar and is evident in one of your photographs.  By needs, we are presuming you want to raise the caterpillar to maturity.  Your photo of the yellow caterpillar indicates it is mature, or fifth instar and that it will soon pupate.  You should continue to feed the Death’s Head Hawkmoth Caterpillar with leaves of the plant on which it was found, and provide it with several inches of loose soil, not too moist and not too dry.  The caterpillar will dig into the dirt to pupate.  When its metamorphosis is nearly complete, the pupa will wriggle to the surface, the skin will split, and an adult moth or imago will emerge.  We would love it if you are able to provide us with images of the adult Death’s Head Hawkmoth.

    Hi there,
    How weird, I live in Glenwood, Durban in South Africa, and I have found also three of these colourful fat sticks on one of my outdoor pot plants. I don’t know how long they were “hanging” there, nonetheless they managed to clean the entire plant of its leaves in two days. Lucky I had a couple of these plants growing in my garden, so I could supply them with extra food. It was drizzling today and I have found them slightly covered with the soil. I don’t know if they are at the end of the cycle or just simply trying to hide from the rain. As I was pushing the stems of the harvested brunches from the other plants into the pot soil I discovered that the soil was compacted and hard. So if tomorrow they are still underground I will move the rascals from the pot to a nice soft spot in the garden. Thanks to Google I found the picture of my caterpillars on your website and after reading your articles about Death’s Head Hawkmoth Caterpillar it helped me to identify the moth responsible for the disappearance of my pot plant and filled my head with some knowledge about these common to the region moth. Thank you. By the way, I really like that yellow horn – does it have any use, and is the number 3 common occurrence -3 caterpillars together?

    Hi I live in southern ireland and found one of these in my garden today. Is it normal to find them in ireland and as I found it on the path I’m not sure what plant it was feeding off. So could you let me know what plants they usually eat please many thanks Laura Thomas

      UK Moths reports Death’s Head Hawkmoths in Britain, and they are likely immigrants from mainland Europe as Hawkmoths are very powerful fliers that are relatively long lived in the moth world. Though they are not reported to have naturalized, it is entirely possible that with global warming, that has changed. A female immigrant from mainland Europe that found its way to Ireland and found an acceptable food plant, like a potato plant in your garden, could lay eggs and produce a caterpillar. Your sighting is highly probable.

      According to UK Moths: “The largest moth to appear in Britain, sporting a wingspan of up to 12 or 13cm, this is a striking species, though it is not native. Immigrants arrive from southern Europe, usually several in each year, during late summer and autumn.” Was the caterpillar found on a potato plant? UK Moths also states: “The large caterpillar feeds on potato (Solanum tuberosum), and is sometimes found in potato fields during good immigration years.”

    We spotted a beautiful looking bright yellow fat Caterpillar strolling across our lawn yesterday morning. It had a funny hornlike tail at the back. Atfer taking pictures of it, we quickly had to remove it off our lawn to the vegetation outside the yard to make sure our little foxie dog doesn’t get hold of it.

    Is this Caterpillar poisonous?
