Occurs in moderately fast flowing and stagnant portions of medium-sized stream (Ref. 75105); flow of about 10 m3/s.. No data on biology known so far. It is still abundant in a very limited stretch of stream (about 25 km long), but s declining, if water abstraction (large quantities extracted for irrigation) intensifies, the whole stream might dry in summer (Ref. 59043).
