Abstract: The morphology of the 1st and 2nd larval instars of A. immaturus (Mulsant, 1842) is described and illustrated here for the first time, with an emphasis on the cephalic capsule, head appendages, legs, and last abdominal segments. The cephalic capsule size was employed to determine the larval instar, while the genital disc was employed to assess the sex of the larvae. The growth and sex ratio of A. immaturus were analyzed.
