An Elephant Hawk Moth :o That'll impress the grandchildren even further. We took a walk round the garden with the 'book' to see if we could identify any other butterflies or moths but there were none. (My Buddleias had a late pruning and are not quite in flower yet)
Mal I have a pic of the caterpillar, a somewhat gruesome looking thing. :-\
Just been out to see if it's still around and it is in the same place as we put it. Given it a tickle and it's still alive.
