Plectophila thrasycosma, Pl. 5.9: Common, 1990.
Plectophila thrasycosma (Meyr.) (Pl. 5.9) occurs in much drier habitats in Queensland from the Atherton Tablelands in the north to the Lockyer Valley in the south. The larva constructs a small spiral case of silk and faecal pellets, and feeds on the leaves of Eucalyptus crebra (Myrtaceae). (Common, 1990).
