Got me stumped

Observation - Got me stumped - UK and Ireland. Description: I was looking at Holly blue or perhaps Common blue female but seems rather tatty and not clear enough to me, any idea would be grateful. I couldn't get a look at the underside as the breeze and speed it shot off as usual over a slope of bramble.
