Nessaea

 ( Biblidinae ) 

Nessaea is a genus of Nymphalidae butterflies found in the Neotropical realm. Unlike virtually all other butterflies with blue coloration, the blue colors in this genus are due to pterobilinDoug Taron, "It's all in the structure", Gossamer Tapestry, Retrieved January 25, 2017 rather than iridescence (e.g., Morpho species).
