The larval stages were observed and characterized under controlled conditions. The larvae were measured and described in order to establish the differences between them, using morphometric characters such as head and premental width and length, number of premental and labial setae, the length of wing pads and legs, and total length without gills, also the growth ratio of different body parts was calculated. The most important character to distinguish larval stages was the head width. There was an increase in the number of
