Buthanitis lidderdalii
 
Bhutanitis lidderdalii, the Bhutan glory, is a species of swallowtail butterfly (family Papilionidae), which is found in Bhutan, parts of north eastern India and of Southeast Asia. A spectacular insect much sought after by collectors, the species epithet is after Dr R. Lidderdale, from whose collection the butterfly was first described by William Stephen Atkinson in 1873. Listed under CITES Appendix II, but not in the Red Book of the IUCN, the status of the butterfly has been recorded as rare by some authorities and "insufficiently known" in the IUCN Red Data Book on swallowtails. The sexes of the Bhutan glory are identical in appearance, having long rounded forewings with convex termen and many-tailed hindwings. The butterfly is dull black above with slim, wavy, cream-coloured striations running vertically across the wings. Above, the hindwing has a prominent, large tornal patch with yellow-orange lunules bordering the tails, central bluish-black patches with white ocelli and a crimson post-discal band on the inner edge. Below, the base colour is greyer, the striations are pronounced and the colours subdued or paler. Wingspan: 90–110 mm. The butterfly is found in Bhutan and north eastern India (Assam, Sikkim, Manipur and Nagaland). It is also found in northern Myanmar, Thailand, Vietnam, Laos and Szechwan and Yunnan provinces of China
