Stactobiella risi (Felber 1908)  
Stactobiella risi.

Distribution: Stactobiella risi has been recorded from many European countries in Central and Eastern Europe, Scandinavia, on the Iberian Peninsula and on the Balkan.

Habitat: Larvae inhabit streams and large rivers (Botosaneanu & Malicky 1978). Graf & Waringer (2002) found larvae attached to periphyton covering the surface of medium sized stones.

Nutrition: Graf & Waringer (2002) characterize Stactobiella risi as a specialised scraping and shredding caddis larva, adapted to stony substratum exposed to high water velocity.

Adults: Adults are on the wing in August (Waringer & Graf 1997).
