Abstract: Life cycle of the stonefly Dinocras cephalotes (Curtis, 1827) was studied in the medium and high course of the river Aniene (Lazio, Central Italy).According to the results, the life cycle in the study area seems to last three years (merovoltine) and seems to show a maximum growth (increase in size of average specimens) in spring-summer.Our results confirm that life cycle of D. cephalotes is clearly influenced by latitude and by the related joint parameters (temperature, day lenght, etc.).First instars individuals found in different periods (March-October) suggest: 1) the presence of two different cohorts with life cycle of different lenght or, alternatively, 2) the existence of an autumm-winter diapause.
