Studies carried out since 1960 on Nudaurelia cytherea cytherea (Fabricius). an insect well known for its economic impact on exotic plantations in the Western and Southern Cape, have shown that gynandromorphs of this species are not common. Out of approximately 250 000 moths handled, only five gynandromorphs were obtained. Four of these were bred from caged pupae while the fifth was found live in the field.
