called Butterfly Journey, which is based around the life cycle of a butterfly, featuring free-flying butterflies and moths (The exotic species on show include blue morphos, giant owls, glasswings, swallowtails and Atlas moths), a cabinet of cocoons, and an area with caterpillars. Also featured in this exhibit is an area for a variety of different invertebrates and a mesh enclosure for some panther chameleons. Big cats As well as jaguars, Chester Zoo keeps lions, tigers and cheetahs in its big cat collection. The lions are the Asiatic subspecies found only in the Gir Forest in India in the wild. The zoo's former resident male Asoka was joined by a female, Asha, from Rome in 2006. The pair have bred on three occasions, but so far their only offspring to survive has been a male cub, Tejas, born and hand-reared in 2007. His upbringing was featured prominently in the first series of Zoo Days. Tejas left Chester Zoo for Besançon early in 2008 as part of the European breeding programme for this subspecies. Asoka left the zoo in early 2010, he was moved to Rome Zoo as part of the European breeding programme. His replacement is 3-year-old Iblis, who arrived from Planckendael Zoo in Belgium. In late summer 2011, Asha retired to Santillana Zoo and was replaced by four-year-old females Kiburi and Kumari. In 2007, a male Sumatran tiger called Kepala arrived from Dudley Zoo to join the two resident female Bengal tigers, who left in 2008. The same year, the zoo acquired a female tiger named Kirana, but unfortunately it was discovered that the pair were related. Kepala departed to Dublin Zoo and a new male named Fabi was brought in from Prague Zoo to form a breeding pair of Sumatrans, a critically endangered subspecies in the wild. Kirana and Fabi bred and have so far bred successfully on three occasions since 2011. The zoo welcomed its first ever cheetah cubs in June 2011. The cheetahs are the vulnerable Sudanese subspecies – a second litter was born in 2013 Asian Steppe Bactrian camels and onagers in a large paddock in the centre of the zoo, formerly the zebra exhibit. A paddock visible from the Bats' Bridge holds a group of Philippine spotted deer.
