This one has a small spot below the big ocelli (eye spot) on underside of forewing which I have not noticed on other meadow brown since that was same as this one. Also this has two spots on hidwing (if you look carefully, you can see them)

Another one, looks slightly greyer than usual, had the normal eyespot on top underside forewing:

This one I noticed was a male, but a littler smaller than usual, found a few of te smaller males on a small wildflower patch:

This is a bad image and I don't usually post such a bad image online, but this meadow brown looked a little strange on upperside, I doubt the pale patches are to do with age since they are on both sides of wings so is this an aberration?:

I know brown butterflies with a lot of ocelli can be variable, less so is speckled wood. Common ones are ringlet, meadow brown and gatekeepers in UK.
