Thanks Bayucca, it's really hard to distinguish, it would a few more photos, unfortunately I have only this one... Looking carefully wings and patches of color, I think you're right and that it's a Pieris napi!

Tricky one! Looking at the edge of the wings I do not think it is Pieris rapae. The black patch should be quite "rectanglar". Pieris brassica would have quite a sharply and roundly black "triangle". Yours seems to have some small spikes at the border which would match for Napi. I can also see some greenish white, however, these are not as consistent as usually seen. This might be due to seasonal forms. Size is at this time of the year not always a criteria for separation. A large Small White might be larger than a small Large White...
I must admit, that the most common ones are sometimes the most tricky ones to determine. What do you think??
