From FB:

Half of this butterfly is male and the other half is female. This is not photoshop or a frankenbug from one of our collections.

Bilateral asymmetrical gynandromorphism can occur in some arthropods. They can form from either the loss of a sex chromosome early in development or from the fertilization of a binucleated egg. In Lepidopterans, males are ZZ (homogametic) and females are ZW (heterogameti
c). The most common way an individual Lep could have ZZ and ZW cell karyotype is through the double fertilization of a the binucleated egg (Z+W).
