Calliphora vicina, micro‐CT‐based virtual sections of puparia at different times after pupariation (AP), reared at 24°C. The correspondent percentage of time of the total intra‐puparial period (IPP) is given in brackets after each time. (a) 18 hr AP (7.5% IPP), medial sagittal section. (b) 18 hr AP (7.5% IPP), lateral sagittal section. (c) 24 hr AP (10% IPP), lateral sagittal section. (d) 24 hr AP (10% IPP), medial sagittal section. (e) 24 hr AP (10% IPP), dorsal horizontal section. (f) 24 hr AP (10% IPP), medial cross section of the thorax. (g) 24 hr AP (10% IPP), medial cross section of the abdomen. amg, adult midgut; br, brain; cc, crystalline cones; cps, cephalopharyngeal skeleton; gb, gas bubble; legs, legs; lfg, larval foregut; lhg, larval hindgut; lmg, larval midgut; ltt, larval tracheal trunks; lsg, larval salivary glands; mp, Malpighian tubules; psp, larval posterior spiracles; yb, yellow body. Arrows indicate sites where larval‐pupal apolysis has occurred
