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 through clearance and fragmentation of subtropical rainforest in jap Australia and the unfold of an alien larval food-plant. Its conservation has concerned many elements of neighborhood involvement, constructed over greater than twenty years, and considering habitat recovery and weed eradication, at the side of conservation of ultimate woodland fragments. The paintings has concerned the complete historic diversity of the butterfly, addressed threats and emphasized panorama connectivity, and has more suitable restoration via huge plantings of local meals vegetation. curiosity has been maintained via wide exposure, group schooling and media task, and the programme has supplied many classes for advancing insect conservation perform within the quarter.

Priamus’ recently reported. However, hybridisation attempts between all three Australian species have not yet confirmed sterility between the species. In view of the ease with which hybridisation (also between genera) can be achieved artificially, it is clear that sterility, or fertility in hybrids between birdwing species or even genera (Sands and Sawyer 1977) especially if they allopatric, are not good indicators for specific status. The name ‘richmondia’ as applied to the Australian subtropical birdwing, has been subject to questioning for its validity.
Alexandrae has been known only from parts of the Oro (formerly Northern) Province, and from only 14 of the 10 × 10 km square mapping units used for plotting distributions of Papua New Guinea butterflies, so appears to be highly restricted geographically. It occurs on the lowlands around Popondetta and in some highland forested areas, particularly around Afore on the Managalas Plateau, and in both these regions (separated by about 40 km) it has been the focus of considerable field survey to clarify its distribution and status.
In general, the categories of conservation concern exemplified for these two taxa have been raised for other birdwing taxa, with varying parallel evidence or concern and the twin threats of habitat loss and over-collecting cited repeatedly. The Yellow birdwing, Troides helena, is often common and widely distributed. However, conservation concerns have arisen from its markedly reduced abundance in Penang, Malaysia, with current interest and support promoted through the Penang Butterfly Farm (Goh pers.
