Ecology: Instream habitat: Hyalopsyche larvae occur in sandy flowing streams shaded or partly shaded by riparian trees. They are found on logs and in leaf packs embedded in the sand.
Feeding ecology: Larvae are detritivores.
Habit: Hyalopsyche disjuncta larvae construct silken retreats consisting of branched tubes attached to or buried in the substrata. This gives them the common name of 'northern tube-dwelling caddis'.
