Biology

O. chimaera is a montane species found in the Central Range montane rainforests. The larvae feed on species of the genus Aristolochia including Aristolochia momandul. The female lays up to 20 eggs on the leaves. Adults feeds upon the nectar of Spathodea (an invasive species) and Hibiscus. Groups of both sexes can be seen circling the tops of these trees in the canopy.
