Can anyone identify these 2 butterflies.No.1 was taken in the Algarve,No.2 in Crete Thank you Jim

Thanks to all who replied.I too felt a bit foolish about not being able to tell the whites apart as I am new to this so it was reassuring to hear I'm not alone.

Thanks for your quick reply Jim

Hello
I'm new to this butterfly ID thing and am a bit hesitant about asking for asking some basic ID on the attached photos.Are they small or large whites? Thank you
