Blue mint garden beetles.
Sorry but this is an answer, not a question.
The beetles I was asking about some 3 weeks ago. For anyone who wants to know we have now found they are called as above.

Best to add your info to your original question as an answer, that way all the GoYers who responded initially will see.
