Typical habitats
Oniscigaster larvae are most likely to be found in pools in stony or gravelly, bush covered streams.
Feeding
Oniscigaster larvae are thought to be detritivores, feeding on streambed algae and decomposing plant matter.
Indicator value
- Hard bottom: 10
- Soft bottom: 5.1
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
The presence of Oniscigaster suggests good habitat and water quality conditions, especially if other mayfly or stonefly groups are also present. They have tolerance values of 10 (hard bottom sites) and 5.1 (soft bottom sites).
