There are 85 known species of Adelpha, all but two of which are confined to Central and South America.
The butterflies are characterised by having a distinctive blackish marbled pattern overlaid on a brown ground colour; and by the presence of a broad orange or white band on the forewings.
The hindwings of most species have a white median band.
Adelpha alala is the only Adelpha species with two separate white dashes near the apeps.
This is the subspecies Adelpha alala negra.

David Geale, an expert on neotropical butterflies and especially the species in Tatamá National Park, helped me identify this butterfly.
I had the great fortune to meet David at the Montezuma Lodge in Tatamá National Park during our visit.
