Annual production was estimated for Trichoptera occurring in three stream habitats of WS 27. Production was greatest on bedrock-outcrops, followed by riffles and pools. Annual production in bedrock-outcrops and pools was dominated by single functional groups, collector-filterers and shredders respectively. Production in riffles was due to a combination of shredders and collector-filterers. Habitat-weighted production was distributed among functional groups: collector-filterers (41%), shredders (29%), engulfing-predators (15%), scrapers (13%), and collector-gatherers (2%). The distinct taxonomic and functional structures of trichopteran sub-communities were shaped by the physical characteristics of their principal habitats.
