Quick Summary

Schizophora is a suborder of flies within the order Diptera. These flies are characterized by a unique feature called the ptilinum, an inflatable sac on their head used to help them emerge from their pupal cases. This sac leaves a distinctive horseshoe-shaped groove, known as the ptilinal suture, on the head of adult flies in this group. Flies, in general, undergo a life cycle with four stages: egg, larva, pupa, and adult, allowing them to adapt to various environments.123
