The Insect House, formerly also a Small Mammal House until 1967, replaced a building that had opened in 1881 to house the world's first public display of living insects. It was also the first building at London Zoo to employ 'aquarium principle' lighting. It was built 1912-13 with a £1,500 benefaction from Sir James K Caird; design by Sir Peter Chalmers Mitchell.
The insects moved to Web of Life in 1999 which was opened by HRH Queen Elizabeth in June 1999. It was renamed B.U.G.S in 2003. It was the first animal house with electricity (cables from the offices).
The Insect House was demolished in 2003 to make way for an expanded Otter enclosure.
Opened in March 2015, In with the Lemurs is a walk-through exhibit housing a group of ring-tailed lemurs. It also has a family of aye-ayes living in the indoor section as well as white-tailed antsangys and lesser hedgehog tenrecs. The exhibit is designed to resemble a shrub forest in Madagascar, featuring plant life such as loquat and Chusan palm trees.
