Stactobiella risi has been recorded from many European
countries in Central and Eastern Europe, Scandinavia, on the Iberian
Peninsula and on the Balkan.
Larvae inhabit streams and large rivers (Botosaneanu & Malicky
1978). Graf & Waringer (2002) found larvae attached to periphyton
covering the surface of medium sized stones.
Graf & Waringer (2002) characterize Stactobiella risi
as a specialised scraping and shredding caddis larva, adapted to
stony substratum exposed to high water velocity.
Adults are on the wing in August (Waringer & Graf 1997).
