Colobura annulata

For once it is the other one, Colobura annulata. Not always easy to separate from Dirce. If you look at the most upper black line on the forewing, in Dirce it is half thin and half very broad, in yours and Annulata it is also half thin, but the other half is also quite thin, definitely not so broad as in Dirce: Dirce: http://butterfliesofamerica.com/imagehtmls/Nymphalidae/Colobura_d._dirce_COSTA_RICA_Ojochal_Hills_Peninsula_of_Osa_1_i.htm Annulata: http://butterfliesofamerica.com/imagehtmls/Nymphalidae/Colobura_annulata_BRAZIL_Mato_Grosso_Cristalino_Jungle_Lodge_05-X-2004_CARTERS_1_i.htm In addition if you look at the anterior part of the forewing, just above the white bar, you see in Dirce an elliptic shaped spot, which is quite typical. In yours and Annulata this spot is not as large as in Dirce and not of this shape, more a broad "pin" or "band" or sometimes just a smaller (compared to Dirce) and roundish patch.
