The Butterfly Thief
Adventure, Fraud, Scotland Yard, and Australia’s Greatest Museum Heist
Walter Marsh’s true crime caper The Butterfly Thief pieces together several mid-century museum thefts that shook Australia’s leading natural history institutions.
In January of 1947, curators at Melbourne’s National Museum of Victoria noticed unexplained gaps in the Lyell Collection, an entomological trove of over 50,000 specimens. Similar checks in Sydney and Adelaide revealed hundreds of missing butterflies. The eventual trail led to a suburban house in Surrey, England, and a British adventurer and amateur lepidopterist with an eye for rare species.
The story begins decades earlier with the fieldwork of Athol Waterhouse and Johnny Hopson, whose expeditions produced crucial discoveries. The related chapters evoke the informal museum culture of the time, when amateur collectors were welcome in storerooms and the lines between scientific contributions and personal gains blurred.
The book’s scope is broad, recounting the thefts, sketching the biographies of scientists and collectors, explaining the importance of holotypes, and situating museum holdings within colonial legacies. Vivid details, as of a painted-over holotype and yellow labels warning of a “Theft Collection,” connect past scandals to contemporary concerns about provenance and integrity.
Although the subject suggests high drama, the narrative is steady, like an archival study. An even tone is used to convey scenes in which curators uncover missing specimens and police pursue leads. Digressions to cover taxonomy and museum design also occur.
The prose is precise, its details sometimes overwhelming but always thorough. The most compelling sections show how theft undermines the historical record of biodiversity. The 2016 discovery of a painted-over holotype underscores the long reach of the crimes and the fragility of collections. By its close, the book resolves the fate of many of the stolen specimens while leaving open questions of ownership, access, and stewardship.
A careful account of Australia’s most notorious museum theft, the true crime book The Butterfly Thief privileges historical and scientific context.
