The first image in the gallery below is of a Gynandromorph. This is an animal that shares both female and male characteristics. This particular specimen is a bilateral gynandromorph, the left side being female and the right side male. Note the differences in the wing sizes and patterns and the antennae (also note the extension of the wing tip in the male side). They are very rare and the contributor Marc Fischer only happened upon it by accident, when ordering silkmoth cocoons from Thailand.
