I just realized you might not even be able to tell where he is:
{{gwi:1347733}}

It is a type of damsle fly. I will try to find what type.

might be Lestes rectangularis

It doesn't look (I googled images) like that lestes you suggested. In images it didn't have the green head and blue tail. But it does look like the damsel fly.... thanks. :) I think it looks like this one: blue tailed.... but it says it is a British species?
