a drier subtropical environment, and are commonly seen in suburban gardens in Queensland and New South Wales. Distribution The known distributions of some of the sixteen recognized subspecies: G. s. sarpedon (Linnaeus, 1758) - India, Sri Lanka G. s. teredon - India, Sri Lanka G. s. semifasciatus - China G. s. connectens - China, Taiwan G. s. nipponum - Japan G. s. messogis - Indonesia, Solomon Islands, New Guinea G. s. islander Monastyrskii, 2012 - Vietnam G. s. wetterensis Okano, 1993 - Indonesia, Lesser Sunda Islands, Wetter Island G. s. choredon - eastern Australia G. s. luctatius - Malaysia G. s. isander (Godman & Salvin, 1888) - Bougainville Island, Shortland Islands, Santa Isabel Island, Guadalcanal, Florida Islands, Choiseul Island. G. s. adonarensis (Rothschild, 1896) - Sumbawa, Flores, Adonara. Status revised to full species by Page and Treadaway (2013) Subspecies found in India occur in southern India in the Western Ghats and in the Himalayas from Kashmir in the west to Myanmar. G. s. milon and G. s. monticolum, however, are not listed here as they are regarded as separate species in a number of works. Behaviour The males are known for their habit of feeding by the edges of puddles, often at the roadside. Occasionally, as many as eight will be seen at the same puddle. They have also been known to be attracted to animal droppings, carcasses and rotting insects. It has been recorded as a migrant in South India and is known to mud-puddle during migration. The butterfly has been seen as comprising as much as 5% of the population of migrating butterflies during a 72-hour period in the Nilgiri hills. The common bluebottle is known for quick flight and rapid reactions. Consequently, it is difficult to catch. Diet The adult common bluebottle feeds on nectar from a variety of flowering herbs. The larvae feed primarily on the leaves of trees in the families Lauraceae, Myrtaceae, Sapotaceae, and Rutaceae. In particular, G.s. sarpedon and G.s. teredon often feed on leaves of the cinnamon bark tree (Cinnamomum zeylanicum) or of the Indian laurel (Litsea sebifera). The list of larval food plants also include Alseodaphne semecarpifolia, Cinnamomum camphora, Cinnamomum macrocarpum, Cinnamomum malabathrum, Litsea chinensis, Polyalthia longifolia, Miliusa tomentosa, Persea macrantha and Michelia doltospa. The larvae of G. s. choredon, native to Australia, feed on many native Australian species of genera Cryptocarya and Litsea; and virtually all subspecies feed on leaves
