More green-eyed flower bee

As I was pottering round the garden today I kept getting drawn to the nemesia and sure enough my little friend was buzzing around on a couple of the occasions. Here's a shot when it had actually landed  and so you can see those enormous eyes more clearly. 
We have a wasps nest and it's in the bush where Eartha made her nest. We don't know if she is still using the nest or not. We haven't seen her for a week in the garden on the night camera. I'm going to ask the wasp man if he can use something that won't hurt Eartha in case she is still using it. We really hoped we could leave it but the wasps are becoming unsociable and I've been reading about how the queens multiply and go on to build more nests.
