"P. glaucus" is one of a few species of papilionids known to produce gynandromorphs. Gynandromorphs, half female and half male, are common. The major types of gynandromorphs, bilateral, polar and oblique are computationally modeled. Bilateral gynandromorphs are easily recognized in this species. Males with asymmetrical forceps are called gynandromorphs or hermaphrodites because they resemble females. Gynandromorphs occasionally afford a powerful tool in genetic, developmental, and behavioral analyses.
