Comma aberration

[petesmith]

Today I came across this rather dramatic Comma aberration in Chambers Farm Wood, Lincolnshire. I only had my bridge camera with me at the time, and as I grabbed it to go in for a photo, it gave me the message "battery empty" - probably the average butterflier's worst nightmare in a situation like this! I reached for my phone instead, and managed a couple of poor shots.

It looks close to ab.reichstettensis, but any comments confirming or challenging this would be most welcome!
