Quick Summary

Pupipara refers to a division within the order Diptera (flies) where the young are born as fully developed maggots, ready to enter the pupal stage immediately after birth. This means these flies do not have an independent larval stage; the larva is nourished internally and develops within the mother before being expelled as a mature maggot. This reproductive strategy is also described as producing mature larvae that are ready to pupate at birth. Examples of pupiparous insects include the sheep ked and horse tick.123
