This year most of the pupae (about 90%), I found in nature were parasitized by
Pteromalus Puparum.
Pteromalus puparum is a small (about 3mm long) parasitic wasp in the order Hymenoptera, superfamily Chalcidoidea, family Pteromalidae, that develops inside butterfly pupae. The wasp deposit eggs inside the skin of the pre-pupa caterpillar or puparial wall of the newly formed pupa. The eggs hatch into larvae, which consume the inside organs of pupa and on maturity turn into pupae. The mature wasps emerges from host pupa through a tiny hole.
Pteromalus puparum is consederd biological control of caterpillar pests particularly cabbage white butterfly and that is why it's known as "Cabbage White Butterfly Pupal Parasite". According to my personal observations the pupae parasitized by
Pteromalus puparum wasp, were include pupae of plain tiger, cabbage white, bath white, citrus swallowtail and ladybug.
