Les, you were at the river when the shots were taken. I have shown you the pics at the river when the shots are taken and asked whether the first one is a Delias.
Was I? I don't remember. I only recall seeing the one P. cornelia. But then, my head was still playing up after my accident (my excuse anyway ).
Anyway, nice to see you starting to show your rarities. and good to see my suspicions on the Drina mariae seconded.
