Tortricidae

Overview

The family is well represented in Australia where all three subfamilies occur, and the fauna contains several tribes regarded as primitive (Horak and Brown, in press). The large subfamily Tortricinae is most abundant in southern Australia, while the other large subfamily, the Olethreutinae, is more diverse in northern Australia. The Chlidanotinae are represented by few species.
