Thanks Guy. You've just saved the life of this brute. I'll move him to an apple tree on our local golf course, where he can eat his heart out. There are not enough leaves left on my tree to see him fed for this year. Lenniew

Thanks Trev. I don't know anything about moths and butterflies, so I've put this thing in a box with plenty of leaves, to see what it turns out to be. Lenniew

Can someone please identify this green monster, which has eaten my young apple tree? It's about 2.5" long. Thanks Lenniew
