Green-veined White

bayucca, Love your passion for the species !

Sure thing, right away! bayucca.

I am still not very happy this one being Pieris brassicae. We should try another effort...

Thanks so much, team bayucca and Marta RubioTexeira :)

Looking at the markings I am happy with Pieris brassicae, but I am not happy with the rectangular-like patch at the edge of the forewing. Brassicae usually have a strongly marked "bow-like triangle", not a square and some "drops"...
For me this one looks like being Pieris napi, female, however, without the strong markings on the dorsal site, which is quite common (seasonal and generation).
