Development of black soldier fly larvae from d 1 after hatching up to the pupal stage. The photographs are showing the development of larvae which were reared on chicken feed together with the corresponding mean body weight (wet weight) of at least 100 larvae; the body weight development corresponds to an 8083 fold increase from d 1 to d 18 (maximum body weight at d 18); each division of the scaling from d 1 to d 18 represents 1 mm; at d 31 the division of the scaling represents 10 mm
