Within the head, gnathal protuberances become apparent. The end of this stage is signaled by the appearance of a distinct cleft at the posterior pole of the embryo, which becomes detached from the vitelline membrane. This marks the beginning of germ-band retraction. Duration at 25 degrees C: approximately 120 minutes (320-440 minutes after egg laying).

comment: Temporal ordering number - 570. DISAMBIGUATION: In Drosophila lab vernacular, the term 'pupal stage' is often used to refer to the entire period from formation of the puparium to eclosion. However, this does not correspond to the standard usage of 'pupal stage' for Cyclorrhaphous flies (for discussion see: FBrf0087128). Briefly: formation of the puparium (hardening of the larval cuticle) marks the beginning of the pre-pupal stage. The pupal stage begins following pupal/larval apolysis - detachment of the larval epidermis from the puparium. In Drosophila, the outward sign of the completion of apolysis is the eversion of the head and expulsion of the larval mouthparts (FBrf0036849). We use P-stage to refer to the stage from pupariation to eclosion, and restrict pupal stage to its standard usage.
has OBO namespace: FlyBase development CV
has definition: Definition
  label: The pupal stage starts once larval/pupal apolysis is complete as indicated by the expulsion of the larval armature. Early in this stage, the legs and wings reach full extension along the abdomen. The stage ends when the pupal cuticle separates from the underlying epidermis (pupal/adult apolysis), and the eye cup becomes yellow at its periphery. Duration at 25 degrees C: approximately 32 hours. (132.2-164.3 hours after egg laying; 12.2-44.3 hours after puparium formation).

comment: Temporal ordering number - 490. DISAMBIGUATION: In Drosophila lab vernacular, the term 'pupal stage' is often used to refer to the entire period from formation of the puparium to eclosion. However, this does not correspond to the standard usage of 'pupal stage' for Cyclorrhaphous flies (for discussion see: FBrf0087128). Briefly: formation of the puparium (hardening of the larval cuticle) marks the beginning of the pre-pupal stage. The pupal stage begins following pupal/larval apolysis - detachment of the larval epidermis from the puparium. In Drosophila, the outward sign of the completion of apolysis is the eversion of the head an expulsion of the larval mouthparts (FBrf0036849). We use P-stage to refer to the stage from pupariation to eclosion, and restrict pupal stage to its standard usage.
