The intrapuparial development of 150 pupae of Chrysomya putoria (Wiedemann, 1830) was analyzed. The material was kept in a climate chamber at 27°C (day) and 25°C (night), 60 ± 10% relative humidity (RH), and a photoperiod of 14:10 (L:D) h, which started at 06:00 a.m. Daily, 30 pupae were frozen at — 15°C, for the sacrifice of the insects, and the immatures obtained were photomicrographed until the emergence of the adults. The following stages were observed: pupariation process: during this process, reduction of the larvae's first three body segments and the darkening of the cuticle occur; cryptocephalic phase after 18 h; phanerocephalic phase after 24 h; body division after 48 h. Between the third and the fourth days of the development, the stage of pharate adult was reached, characterized by the following changes in the color of the compounds eyes: 1) orange eyes, after 66 h; 2) red eyes, after 72 h; 3) dark red eyes, after 90 h; 4) brown eyes, after 96 h. The time of intrapuparial development of C. putoria at 27°C (day) and 25°C (night), 60 ± 10% RH, and a photoperiod of 14:10 (L:D) h was 5 d.
