  • Taxonomic Checklist: Genera
    Taskiropsyche (larva unknown)

    Distribution: Vic, Tas

    Sensitivity Rating: SIGNAL grade 3

    Functional Feeding Group: predators

    Ecology: Instream habitat: Kokiriid larvae appear to be strongly associated with stable sand deposits in runnels, streams and lakes. Generally they are found in low numbers.
    Feeding ecology: Larvae are predatory with the fore- and midlegs strongly modified for prey capture. They are commonly known as ‘killer caddis’.
    Habit: Larvae construct a tubular case of sand grains, depressed dorso-ventrally, with lateral flanges.
