Ornithoptera richmondia
The Richmond Birdwing (''Ornithoptera richmondia'') is a species of birdwing butterfly that is endemic to Australia. It is the second smallest of the birdwing species, the smallest being ''Ornithoptera meridionalis''.
==Distribution==
Historically, ''O. richmondia'' is recorded from rainforests southwards from Maryborough to the Clarence River in New South Wales. Due to widespread habitat loss throughout its range, its distribution is much more restricted, especially in Queensland. Its present-day range is from Kin Kin and Pomona, North Arm, Yandina, Coolum (although this population is now extinct due to drought), Parklands and Nambour, Diddillibah, Buderim, Eudlo, Palmwoods, the Mooloolah and Diamond Valleys, the entire Blackall Range southeast from Kenilworth to the state forest near the Caloundra Turnoff and west to Peachester and the Stanley River, and the Conondale Range southwards to Mount Mee.
South of Brisbane, the species is recorded along the Nerang River and the Tallebudgera Valleys and has an important stronghold in the national parks adjacent to the Queensland-New South Wales border. In New South Wales, the species is widespread in rainforest southwards to the Blackwall Range near Wardell and the Cherry Tree State Forest near Mallangangee (Braby 2000, Sands & New 2002, Sands & Scott 1997). Note that although the species may be abundant at altitude (e.g. the QLD-NSW border ranges national parks), these populations typically die out due to cold winter temperatures and require migration of adults from the lowlands for persistence. Population sizes in these habitats therefore vary from year to year.
A recommended viewing locality for this species is the car park at the base of the summit trail to Mount Warning in Mount Warning National Park, New South Wales. Given good weather during their flight period, sighting this butterfly is almost a certainty.
