Habitat: This species inhabits lower reaches of rivers and streams with higher current velocity (Botosaneanu & Malicky 1978, Tobias & Tobias 1981, Robert & Wichard 1994, Edington & Hildrew 1995, Waringer & Graf 1997). Larvae are usually found in small numbers; however they can be quite common in the outflows of lakes (Edington & Hildrew 1995).

Nutrition: Larvae are scrapers and filter feeders, feeding on aufwuchs, detritus and small invertebrates (Waringer & Graf 1997, Graf et al. 2002).
