Larvae of Australian Hydrobiosidae (Insecta: Trichoptera).

Northern Australia is one of few tropical places left on Earth in which biodiversity — and the ecological processes underpinning that biodiversity — is still relatively intact. However, scientific knowledge of that biodiversity is still in its infancy and the region remains a frontier for biological discovery. The butterfly and diurnal moth assemblages of the area, and their intimate associations with vascular plants (and sometimes ants), exemplify these points. However, the opportunity to fill knowledge gaps is quickly closing: proposals for substantial development and exploitation of Australia’s north will inevitably repeat the ecological devastation that has occurred in temperate southern Australia — loss of species, loss of ecological communities, fragmentation of populations, disruption of healthy ecosystem function and so on — all of which will diminish the value of the natural heritage of the region before it is fully understood and appreciated. Written by several experts in the field, the main purpose of this atlas is to compile a comprehensive inventory of the butterflies and diurnal moths of northern Australia to form the scientific baseline against which the extent and direction of change can be assessed in the future. Such information will also assist in identifying the region’s biological assets, to inform policy and management agencies and to set priorities for biodiversity conservation.

The first reference to describe the 70 hepialine Hepialidae species in Australia.

The Hepialidae (Ghost Moths) are a family of often spectacular micro-moths. The Australian region is one of the hot spots for hepialid diversity and the fauna is divided into three groups: primitive Hepialidae with small, often overlooked species; oxycanine Hepialidae, containing the large and poorly known genus Oxycanus and its allies; and finally the hepialine Hepialidae, which span from stunning, green Splendid Ghost Moths in the genus Aenetus, to the enormous moths in the genera Zelotypia and Abantiades(which include some of the most impressive insects in the world), to smaller, drab pest species in the genus Oncopera.
