Caddisfly nymph (Genus: Hydrobiosis)
Subclass: Pterygota (caddisflies)
Common name: Common green free living caddis
The free living New Zealand hydrobiosid caddis larvae are common in stony streams all over New Zealand, in bush-covered and farmland areas. They are predators, feeding on other stream invertebrates.
They have pincers on their forelegs. Several of the common hydrobiosids depending on the species, the prosternal plate (shield-like structure between the forelegs) may be a single, roughly square plate (e.g. H. parumbripennis and H. centralis), or divided into 3 pieces (e.g. H. clavigera and H. silvicola).
