Ptilinum

Definition

In the Schizophora, this is an inflatable bag in the front of the head which is used by the emerging fly to push off the end of the puparium. The ptilinium emerges above the antennae causing the face to hinge forward and downwards. Once the fly has emerged, the bag is withdrawn and the face returns to its normal position, leaving the ptilinal suture marking the join.
