Typical habitats
Hydrobiosella larvae are common in many stony bush-covered streams.
Feeding
They are known to be both collector-gatherers (feeing on organic detritus and algae) and predators (feeding on other stream invertebrates).
Indicator value
- Hard bottom: 9
- Soft bottom: 7.6
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
An abundance of Hydrobiosella larvae indicates good water quality, particularly where mayfly and stonefly nymphs are also abundant. They have high tolerance values of 9 (hard bottom sites) and 7.6 (soft bottom sites).
