In reply to Michael Hood:
Most likely Common, but is it a possibility of being Holly Blue? Holly Blue just gets as far north as Fife (a few exceptions) and so I’m keeping a look out of one! Other blue butterflies area less likely than Common, or maybe Holly, I would have thought in your general area.
BTW, checking bird reports, I see a Lesser Yellowlegs is at Leighton Moss if you are visiting. Saw one last year when it visited St Andrews in July.
