Triplectides caddis larvae construct mobile cases primarily out of plant matter, but they also occasionally use stones or the cases of other caddisflies. The plant cases can be a hollowed piece of stick, or a tubular collection of many plant fragments. Their hind legs have distinct dark bands between the leg joints.
Triplectides larvae are common in hard bottom and soft bottom streams, in areas of bush cover, farmland and sometimes urban landuse.
They are shredders, feeding on leaf litter (and the microbes decomposing the litter).
- Hard bottom: 5
- Soft bottom: 5.7
The tolerance values (ranging from 0 to 10) give an indication of which are the sensitive taxa (values of 8 or more) and which are the tolerant taxa (values of 3 or less). For more information see: Indicator species
Triplectides can occur in streams with moderate pollution, so they are not necessarily an indication of good water quality. They have tolerance values of 5 (hard bottom sites) and 5.7 (soft bottom sites).
