Genus: Anisocentropus
This family is represented in Australia by a single genus, Anisocentropus Mclachlan.

Descriptive Features:

  • pronotum with long rounded projections at the anterolateral corners
  • mesonotum moderately sclerotised and usually with a dark inverted "V" of stronger sclerotization
  • metanotum with 3 pairs of very small sclerites each with long setae
  • metasternum without setae
  • hindlegs very long, at 2X length of the forelegs
  • abdomen flattened, with divided gills and with a strong lateral fringe of setae
  • Total length: 8 - 12 mm
    Case: Flat, made of only 2 pieces of leaf material.

    Ecology: Instream habitat: Calamoceratidae species are found in both fast flowing riffle zones and slow flow areas of cool streams and in backwater areas of large, warm lowland rivers or lakes. Larvae are found in areas where detritus accumulates. Pupae are commonly found attached to rocks but some may be found in leaf litter.
    Feeding ecology: Larvae are detritivores feeding on coarse plant detritus. First instar larvae move between the epidermal layers of leaves to feed on the internal tissue.
    Habit: Larvae construct a dorso-ventrally flattened case, from two pieces of leaves, that resembles a bag, giving rise to the common name of ‘sleeping bag caddis’.
    Life history: Females lay their egg in masses attached to the surface of leaves within litter packs. Eggs hatch after three to ten days. Larvae generally undergo five instars. Northern Australian species emerge almost all year round. More southern species may have reduced emergence over winter.
