    Functional Feeding Group: predators

    Ecology: Adults are commonly known as 'southern darners'.
    Instream habitat: Telephlebid larvae are found in fast and slow flowing waters in alpine to rainforest and dune situations. Stream types vary from trickles and runoff waters to upper reaches of rivers and small streams dominated by bedrock and boulders to temporary streams and streams that dry to pools in summer. Larvae are found in a variety of microhabitats; heavily vegetated with aquatic macrophytes, rocks, tree roots on the sides of the pools, sphagnum, cobbles, sandy substrata, leaf packs, detritus at bottom of pools, gravels, crevices of logs or in the splash zones of waterfalls. Antipodophlebia is possibly semi-aquatic, having been collected away from the stream in damp leaf litter.
    Feeding ecology: Larvae are predators.
    Habit:
    Life history: Females lay their eggs in submerged, rotten logs or damp, mossy rocks.

    Key Note: The key to genera of Telephlebiidae is best used for the identification of late instars. From early to late instars there may be marked change in the proportions of even strongly sclerotised structures like the prementum or of spines and processes. The changes may even proceed in different directions depending on species.
