Yes Bayucca, the same one.

You mean this one?

Thank you Bayucca, I put a reference with some pinned specimens collected in my province. :)

I think we are still on the safe side with Chioides catillus catillus.

I added two pictures to this series to improve the identification of this butterfly.

Ok Herr @Bayucca, haben Sie Recht. Vielen Dank für Ihre Hilfe und für Ihre Aufmerksamkeit . Sehr nett von Ihnen.

In this case it is not Urbanus dorantes but Chioides catillus catillus. Dorantes has a shorter tail, no red spots at the ventral side of the hindwing and the markings are slightly different.

Hi @bayucca, yes is the same individual.This butterfly was a long time in a ginger leaf in the sun with its wings spread and then it moved to another near plant. I remember that I followed it for a long while. :)

Are #1 and #2 the same ones??
