NOT a Small Tortoiseshell - a Comma

Another warm and sunny day although it looks as though it might rain later.
 
A morning of sorting out my address, telephone number and email addresses, something what has needed doing for a while.
 
I have also signed up for some online training this week with the Open University, which is good as it gives me some structure to my days.
  
Today’s picture is, I think, a Small Tortoiseshell butterfly although its markings are not particularly striking.

Update - It is a Comma thanks Nickimags888 for identifying this for me.
