Thistle with Fritillary

I think the butterfly on this thistle is a Small Pearl-Bordered Fritillary.

Our Tuesday walk was to climb Dunsinnan Hill and follow the ridge to King's Seat. Dunsinnan (with the stress on the second syllable) is the Dunsinane of Shakespeare's Macbeth. It does have an Iron Age fort and may have been occupied up the the time of the real Macbeth and Malcolm.

However it's a very long way from Birnam Wood to here, so Shakespeare's knowledge of Scottish geography was obviously sketchy.
