Philaethria dido
Your ID is in principle correct, but in Mexico til Panama this guy is called Diatonica. If you follow the discussion in the link above, you may see that even a very famous nymphalid expert didn't know that. My ID was confirmed by Kim Garwood, also an expert. In South America there are several other species of Philaethria besides of Dido. They are a nightmare to separate.
