On the Mull Tour earlier in May of this year we were watching a family of Stonechats from the vehicle when an interloper flew in through one of the windows.
This was one of a couple of Green Hairstreak Butterflies we saw during our time on Mull. I thought it looked a little different to the ones I’ve seen in Norfolk, perhaps a little browner and a little cleaner cut which begged the question does Mull harbour a different subspecies? Having referred the matter to Greg my local Lepidopterist, who’s knowledge of these things far exceeds my own, a subspecies on Mull is not known.
