Marbled White (Melanargia galathea).
Female Marbled White on Agrimony, with flowering Agrimony as a backdrop.
This is probably my favourite photo from 2021. Most years the Marbled White seems to be up there with my favourites as it is such a photogenic species.
This newly emerged female performed really well for about 20 minutes landing on both the Agrimony and Viper's Bugloss during the time I spent with her.
