Blue butterfly

I don't know anything about butterflies but saw this in my garden. If anyone knows what it is, please let me know. I just thought it was a pretty little thing and liked the sheen on it's wings. It wouldn't oblige by sitting with its wings completely outstretched but never mind I still thought it was pretty. I just cropped it a bit otherwise SOOC

Could be a Common Blue, they're the only blue ones I know.

and think it is a small blue.

Beautiful Butterfly! Glad you caught him so well, nicely done, Rosie!

He could be a Holly Blue,if the other side of his wings is a little darker.Well captured,anyway

@esox Thanks for the link. I think it could be a Holly blue and it was on the holly bush but somebody else suggested a small blue so I think it might be one or the other.

@mummymorris @grammyn @carolmw @kbuehl Thanks for your lovely comments and @moominmomma I think you could be right, it might be a holly blue as it was on the holly bush at the time
