There was a young moth on a pin
Whose sex parts were not left within.
He cried out, "Alas,
They are placed under glass,
And mating's frustrating as sin!"

ABSTRACT
A gynandromorph is a non-human animal with both male and female attributes - an hermaphrodite in humans. With lepidopteran gynandromorphs, often only a dorsal view of the adult is illustrated with photographs, showing male wings on one side and female wings on the other. But, sometimes only the genitalia exhibit gynandromorphy, as is the case with this specimen.

The artist, who often studies specimens more intensively than others, may perceive subtleties that provide insight into anatomic relationships. Because of my experience studying anatomy of moths, I was asked to draw an unusual specimen, which externally looked like a normal female but internally had an amalgam of male and female genitalia, and to determine what parts corresponded to normal anatomy. Some of the parts were not in their usual positions and were deformed.

The drawings attempt to interpret the specimen's anatomy and demonstrate homologies between male and female parts in evolution, i.e., how one structure develops into a male or female part. Drawings of this abnormal specimen are compared with drawings of normal male and female genitalia of the same species.
