Lateral trunk tracheae become obscured. Dorsal medial abdominal contractions occur. Everted leg and wing discs become visible. Bubble appears in posterior of puparium, displacing the pupa anteriorly; abdominal bubble disappears. Duration at 25 degrees C: approximately 5 hours, 15 minutes. (126.75-132 hours after egg laying; 6.75-12 hours after puparium formation).
