Mimic-White

I am sure it is the Ecuadorian subspecies Dismorphia lewyi leonora and it is the male. There are not many pictures of it, but these ones are a perfect match: http://www.butterfliesofamerica.com/L/ih/n_dismorphia0151_i.htm http://www.sangay.eu/ficha-principale.php?ref=81&lang=en The ID Dismorphia lewyi leonora is safe.

Pieridae (!), Dismorphinae, Dismorphia lewyi leonora, male.
