Galacticidae

Overview

The greyish mottled adults remind one of species of Prays (Yponomeutidae). Larvae of Homadaula myriospila live in communal nest of webbed phyllodes of Acacia ligulata and pupate in a dense, white cocoon amongst dead phyllodes and faecal pellets in the middle of the webbed mass. [Clarke 1943; Kyrki 1990; Moriuti 1963.]
