A great find this morning in the garden, although, it was the dogs that found it, not me!
This is a Death’s-Head Hawkmoth Caterpillar, the name comes from the pattern of a skull on the back of the moth. I have never seen the actual moth, but have put a library photo at the end. There are 3 species of this moth, this one is the African Death’s-Head Hawkmoth with the scientific name of Acherontia atropos, the other 2 species (Acherontia lachesisare and Acherontia styx) are found in Asia.
This Caterpillar is one of the largest I’ve seen, even bigger than the Elephant Hawkmoth. It was around 12-14cm in length and over 2cm wide. In fact it was so long that I struggled to get it all in focus, even with a small aperture.
When approached they click their mandibles as a defense tactic, although it’s not very loud. I relocated it away from the dogs to go about its business.
