Butterfly on the heather

This is, I am saying this with SOME confidence, a small tortoiseshell on the heather up on the heath behind the house.   Now i have identified it (via iNaturalist, thanks for the tip @xtoph) I am surprised it is so small, I always assumed there was a big tortoiseshell but it seems not.  I am not v g at butterflies but I am working on it! 

Lovely having a day at home catching up in the office, walking at lunchtime and in the evening picking sweet peas in the garden.  And still being very productive.  V had to go to London again.
