stage P15 pharate adult stage P15(i) pharate adult stage P15(i) pupa DEPRECATION WARNING. fly_anatomy.ontology This is the stage immediately prior to emergence. It is characterized by the black appearance of the wings, frequent movements of the legs and the presence of the meconium, a pale green patch which appears at the posterior tip of the abdomen. Wings at this stage closely resemble those 87hr after pupariation as described by Tucker et al., (1986). The cuticle is highly folded, and numerous epidermal cell processes containing transalar microtubule arrays span the lumen. Malpighian tubules and yellow body become obscured by tanning of the tergite. Legs twitch (flies can walk if dissected from puparium). FBbt:00005367
