General information
The first description of this butterfly was in 1775 by Cramer. There are only two subspecies.
- Morpho rhetenor cacica [Staudinger, 1876]
- Morpho rhetenor helena [Staudinger, 1890]
The brilliant blue is a characteristic of nearly all members of genus Morpho. The blue structure colour based on the phenomenal microscopic structure of the scales. The interference erase all wavelength of light except for blue light. Therefore the wings are blue although there are no pigments.
Here you can see the subspecies Morpho rhetenor helena (male).
