キアゲハ♀とアゲハ♂の種間雑種

抄録

1. A copulating pair between Papilio machaon hippocrates ♀ and P. xuthus ♂ was captured on April 30, 1967, at Hamamatsu, Shizuoka Prefecture. Interspecific copulations between these two species seem very rare in nature. 2. This hippocrates female laid seven eggs. Five of these eggs started to develop and two of them hatched. One larva did not feed on Parsley, but Natsumikan (Citrus natsudaidai HAYATA), and another fed on Parsley. 3. Ground color of the 5th instar larva fed on Parsley was dark yellow, and one fed on Natsumikan was pale green. These larvae grew faster than P. xuthus larvae which were reared at the same time, but were smaller. 4. Ground color of the hybrid pupae were both yellowish light brown and the shapes resemble pupae of hippocrates. 5. These two pupae emerged as males. These hybrid adults more resemble hippocrates adults than xuthus adults in general.
