The orchid tit, Chliaria othona[2][3] is a species of lycaenid or blue butterfly found in Asia.

Orchid Tit is one of the rare butterflies belonging to the family Lycaenidae (Kehimkar, 2008). This butterfly is fairly common in Northern India, but was reported to be very rare in Southern India. In India, Chliaria othona is distributed in the Western Ghats, Uttaranchal to Arunachal Pradesh, the Northeast, West Bengal and Andaman Islands. It was also reported from Nepal, Bhutan, Bangladesh and Myanmar. Orchid Tit prefers wet forests of up to 1524 meters altitude from the mean sea level and occasionally visits damp patches for mud puddling.[4] The caterpillars of Orchid tit feed on the flower buds and flowers of orchids,[5][6] and hence the name.

The orchid tit is to be found in dense, rainy jungles. It is rarely seen except around its food plants - the flower buds of epiphytic orchids. It flies weakly and settles on flowers, leaves. It visits damp patches.[7]

Life cycle

Caterpillar - Green onisciform larvae with red dorsal band and three red rippled lines on each side. The caterpillar's head is concealed and its body is covered with minute bristles. Distinct short protuberances extend from the anal segment. It feeds on the flowers of the orchid.[9]

Pupa - Smooth and greenish-grey, resembles those of other Lycaenidae spp. It has a few white markings, with a distinctly wavy pattern on the wing covers. It is found fastened along the stem of the orchids.[9]

Larval food plants - The orchid tit's larval host plants are from the family Orchidaceae from genus Arundina, Dendrobium, Papilionanthe, Phaius, Phalaenopsis, Spathoglottis and the specific species are Papilionanthe subulata and Spathoglottis plicata [10]
