This survey of 1 the longest insect conservation campaigns in Australia offers with restoration of 1 of the main iconic endemic butterflies, the Richmond birdwing, threatened by way of clearance and fragmentation of subtropical rainforest in japanese Australia and the unfold of an alien larval food-plant. Its conservation has concerned many elements of group involvement, built over greater than twenty years, and fascinated with habitat recovery and weed eradication, along with conservation of final woodland fragments. The paintings has concerned the whole historic diversity of the butterfly, addressed threats and emphasized panorama connectivity, and has stronger restoration via huge plantings of local meals crops. curiosity has been maintained via huge exposure, neighborhood schooling and media task, and the programme has supplied many classes for advancing insect conservation perform within the area.

To ensure that insects are treated locally as a renewable resource. 8. To promote the conservation of butterflies and their habitats. The demonstrated success of ranching birdwings based on habitat enrichment is important for the Australian study discussed in this book but, whereas the practice has become wide-ranging in both scope and purpose, it has not wholly replaced the need for additional species-focused conservation measures. Perhaps understandably, in view of the dearth of concerned resident entomologists and the pressing problems of human welfare, such conservation concerns tend not to be seen to help solve these problems in Papua New Guinea.

Some threatened species in these groups have proven to be of serious concern and have become important flagships for insect conservation in the region. Papilionidae are not within that regional spectrum of priority concern, and many of the above species occur only on small, remnant habitat patches – in some instances within or near urban regions – so that the conservation needs are strongly site-orientated and remedial measures can 26 1 Birdwing Butterflies and Their Conservation Needs be defined clearly.

Mating usually continues for several hours with both sexes opposite under a leaf while holding wings closed. Hand-mating was successfully manipulated when outcrossing was required for inbreeding depression studies (Chap. 8, Fig. 4). 2 Biology 35 Fig. 4 Ovipositing female of O. richmondia: note conspicuous thoracic red patch (L. 1 Effects of Plant Nutrients on Larval Development and Adults The distribution of Pararistolochia vines, and several other rainforest plant genera in Australia and Papua New Guinea, indicates the dependence of birdwing immature stages on nutrient-rich food plants that grow on nutrient-rich soils, particularly basaltic soils or volcanic alluvium such as that surrounding the volcanic core of Mount Warning (Fig.
