Abstract：[Obiectives] The morphological ontogeny of the gall midge, Aphidoletes aphidimyza (Rondani), was described based on laboratory-reared specimens in order to provide a basis for the identification of A. aphidimyza. [Methods] The larvae of A. aphidimyza were originally collected in the field, then reared in a laboratory chamber at (25±1)℃, 85%±5% RH under a photoperiod of 16︰8 (L︰D). We collected individually reared eggs, larvae, pupae and adults from the colony and described the detailed morphological ontogeny of each stage using digital methods and electron microscopy. [Results] The developmental time of A. aphidimyza, eggs was 2-3 days, and the larval stage had three instars which developed over 5 to 8 days. The pupal period was 7-10 days and the adult stage was only 3-4 days. [Conclusion] The morphological ontogeny of A. aphidimyza provides a useful foundation for the identification and classification of this species.
