The larval instars, seasonal occurrence and environmental factors influence on Psaroniocompsa incrustata (Lutz, 1910) (Diptera: Simuliidae) immature were studied according to its physical and chemical aspects of breeding water. Four collects were made at vegetal substrate from margin, middle and floating on the Pium river, city of Nísia Floresta, state of Rio Grande do Norte, Brazil at dry and wet season. Some of larval characters were used to determinate the larval instars number like lateral length of cephalic capsulae, antennae and the distance among cephalic apodema, as well as pH, water temperature, width, depth, stream velocity, discharge and pluviometric precipitation were used for physical factors. Seven larval instars were determined for this P. incrustata community being the lateral length of cephalic capsulae as the best structure with this meaning propose. The seasonality immature abundance of this species were found in dry season and a positive correlation with pH, stream velocity and precipitation
