Explanation of Names
From Greek adelphos (αδελφος)- "brother, son of the same mother" with the masculine ending -os changed to a feminine ending -a

The common name could be interpreted as a translation of the scientific name, but is usually said to refer to a nun, whose traditional clothing/habit is dark with white like the predominate colors of these butterflies.
At least 20 species are known from Mexico. Only three have been recorded from the US, two of them only in the Lower Rio Grande Valley in southern Texas.
See Also
The Silver Emperor (Doxocopa laure) and Pavon Emperor (D. pavon) strongly resemble members of this genus, though they actually belong to a separate subfamily (Apaturinae)!

Lorquin's Admiral is also very similar.
