    Distribution: all states 

    Sensitivity Rating: SIGNAL grade 4

    Functional Feeding Group: predators


    Murray River, Yarrawonga Vic

    Ecology: Adults are commonly known as 'threadtails or pinflies'.
    Instream habitat: Nososticta nymphs occur in streams, rivers and lagoons, often inhabiting the submerged root masses of riparian vegetation or associated stream macrophytes. Some adults prefer shaded habitats, especially closed canopy rainforests.
    Feeding ecology: Nymphs are predators.
    Life history: Females of Nososticta kalumburu lay their eggs in the stems of aquatic macrophytes or the roots of terrestrial plants that hang into the water.
