Genital photoreceptors have crucial role in oviposition in Japanese yellow swallowtail butterfly, Papilio xuthus [PDF]

open access: yes, 2001
Butterflies of both sexes have two pairs of extraocular photoreceptors on the genitalia. Here we demonstrate in female Papilio xuthus that a pair of the genital photoreceptors, P1s, is crucial for oviposition.
