Little Savages was created by artist Tessa Farmer, who spent a year researching the predatory nature of insects at the museum, and worked with scientists from its Entomology Department.
The installation shows a group of fairies, created with plant roots and insect wings, staging a fierce attack on a fox, and there are also drawings showing Farmer's experience of working in the scientific laboratories, studying the parasitic wasp, which habitually invades and devours other creatures.
Farmer has also created a stop-motion animation with Sean Daniels, revealing a 'behind-the-scenes' attack by the fairies in the museum's storage areas, where a single fairy lures a longhorned beetle out from a cave, which is then pounced upon by a horde of predatory fairies.
The installation will be on show in the museum's Central Hall until January 27 2008. www.24hourmuseum.org.uk
