CONSERVATION
IUCN Redlist category Least Concern (IUCN 2020)
Rationale for redlist categorization Graphium macfarlanei has been assessed as Least Concern. This widespread species has a large extent of occurrence spanning areas of Australia, Indonesia and New Guinea. The species overall is a host plant generalist, utilising a large number of Annonaceae species, including ornamental plants in urban centres. Overall, although the species is considered to be uncommon in parts of its range, e.g. Australia, it is unlikely to be declining. While localised threats may affect the species in certain localities, there are no known widespread and significant threats to this species. (IUCN 2020)
Described Threats This species is widespread; while localised threats may exist for the species, i.e. from localised habitat loss, it is unlikely to be threatened in any major way. (IUCN 2020)
Commercial use This species is farmed and collected for trade in Papua New Guinea (Collins and Morris 1985), and has been reared and exported from the Solomon Islands (Leary 1991). (IUCN 2020)
Applied conservation actions This species was not considered to be threatened in a previous status assessment of the world's swallowtails in 1985 (Collins and Morris 1985). Although it is considered one of the rarer species of Papilionids in Australia, the species across its range is not considered to require any targeted conservation action (Peggie et al. 2005). It also occurs in protected areas across its range, such as Iron Range National Park (Dunn 2006). (IUCN 2020)
