Morpho rhetenor helena - A mosaic gynandromorph

Morpho rehetenor helena mosaic

Pictured here is a fine example of a Morpho rhetenor helena mosaic gynandromorph. 
The left side of this butterfly is all male, whilst the right hand hind wing is almost all female. This is a very striking example as the male and female of the species are so different.
