Mazzab - You have captured it beautifully. Did you notice at the apex of the roll the wings are opened slightly? I have seen this before in other species. I’m glad the video came out ok, it was only shot through my phone so quality can be a bit hit and miss. I must admit I don’t think it’s somethin...

Just to add to the conversation, I captured this short 18 second video of a Holly Blue ‘wingrolling’ today.
