Tryons Hawk Moth

A couple of Alocasia plants (not sure exactly which one it is) have been decimated by a caterpillar or two -  they have been difficult to spot but tonight using a torch I found this very fat one:

It is  the caterpillar of a hawk moth - binomial  name is : Theretra tryoni
There are typical eye spots one end and a horn like extension on the other mouth end.  Size of this one was 7cm although when rolled over it did lengthen more than that. As it's probably near to becoming a pupa, it has been placed into a container (with some food) for keeping  until it becomes an adult moth. I have always been amazed by metamorphosis - how the tissues of the caterpillar are basically completely reorganised to become an adult moth or butterfly. Some time ago I read up on it and it is as a way of  reducing food competition between juveniles and adults and is understandable as "suspended" development.
