Morning Visitor ( Black-tailed Skimmer, I think!)

Went to open the greenhouse this morning and found this dragonfly balanced on a cane, not what you expect to see but most pleasing.

It even held on long enough for me to go and get my 70-200 which was very kind.

I think having looked at a few sites that it is a black-tailed skimmer but if anyone knows better I am happy to be educated
