Calliphora vicina, micro‐CT‐based virtual sections of puparia at different times after pupariation (AP), reared at 24°C. The corresponding percentage of time of the total intra‐puparial period (IPP) is given in brackets after each time. (a) 42 hr AP (17.5% IPP), medial sagittal section. (b) 48 hr AP (20% IPP), lateral sagittal section. (c) 48 hr AP (20% IPP), latero‐medial sagittal section. (d) 48 hr AP (20% IPP), dorsal horizontal section. (e) 48 hr AP (20% IPP), medial horizontal section. (f) 48 hr AP (20% IPP), ventral horizontal section. ahg, adult hindgut; amg, adult midgut; an, antennae; as, air sac; asg, adult salivary gland; br, brain; cps, cephalopharyngeal skeleton; crn, cornea; dlm, dorsal longitudinal muscles; dvs, dorsal vessel; legs, legs; lsg, larval salivary glands; on, optical nerve; rp, rectal pouch; tg, thoracic ganglion; wg, wings; yb, yellow body. Arrows indicate sites where pupal‐adult apolysis has occurred
