English sub-species?
Whilst gardening, I uncovered a very similar, if not identical, caterpillar. It was brownish/grey in colour and had the horn at the end of its tail. I live south of London. Is there an English or European sub-species of the Tersa Sphinx? Unfortunately, it really grossed me out and I had my husband throw it into the rather large field behind our house. I am certain that it matches image 6481 . Please advise as to where I can find more info. It was on the floor very near a similar looking plant as is in your image.

thank you. Cheers!
