Morpho menelaus guyenensis - A mosaic gynandromorph

 

Morpho menelaus guyenensis mosaic gynandromorph

Here is a fine example of a field collected, mosaic gynandromorph of Morpho menelaus guyenensis. You will notice that the lower quarter of the right hand hind wing shows the female pattern quite clearly. 
There are also just a few female scales on the lower part of the right hand fore wing. The abdomen is completely male.
