Meconema Nymph

We came across a Bush Cricket yesterday as we were harvesting Pears from the tree in Mrs Catspaw's parents' back garden, but it was gone before I had a chance to go for my camera.

Then by chance this morning - after a night of really heavy rain - I came across this nymph on the foliage of a Chinese Juniper (Juniperus chinensis) in our own back garden. I'm pretty sure it's either an Oak Bush-cricket (Meconema thalassinum) or a Southern Oak Bush-cricket (Meconema meridionale), but (as explained here) it's not easy to be sure exactly which it is.
