In Japan, the sight of a mosquito in late summer is almost a cultural marker, a signal that the season is turning and that nature, as ever, demands its toll. Across the Asia-Pacific, blood-feeding creatures occupy a peculiar space in the human imagination: feared, reviled, occasionally romanticised, and almost universally misunderstood. Sydney's Australian Museum is about to change that, with the arrival of Bloodsuckers: Legends to Leeches, an internationally touring exhibition that makes a serious scientific and cultural case for respecting the creatures that feed on us.
The show, originally developed by the Royal Ontario Museum in Canada, has already drawn visitors in Chicago and Auckland before landing in Sydney. It covers the full sweep of nature's vampires, from mosquitoes, ticks, fleas, and leeches to the myths, legends, and pop-culture obsessions those creatures have generated across millennia. According to the Sydney Morning Herald, which previewed the coming attraction, the show is not for the squeamish, though its designers have deliberately worked to balance the creep factor with genuine wonder.
That design challenge was considerable. The objects at the heart of the exhibition are, in most cases, tiny enough to sit in the palm of your hand. The creative response was to build large: oversized models of mosquitoes, leeches, and blackflies generate wonder about these intricate, small creatures. Alongside these sculptural centrepieces, an 18th-century-themed room details the history of bloodletting, where graphics, live specimens, and a rare collection of artefacts combine to create the historical atmosphere. There is also a mini-movie theatre mid-journey, featuring a montage of the bloodsuckers that have haunted human storytelling from Dracula to Twilight, and a diversity wall packed with magnified specimens and touchscreen interactives.
Very little realistic blood appears in the exhibition; the beauty of the natural world is emphasised and the tone is lightened with humour, whimsy, and fun interactives. That is a careful curatorial choice. The designers knew they were working with subject matter that triggers strong visceral reactions, and they set out to convert discomfort into curiosity. The exhibition won the American Alliance of Museums' Excellence in Exhibitions Award, a recognition that the approach worked.
More Than a Curiosity
For Australian visitors, the exhibition carries a weight beyond entertainment. Blood-feeding creatures are not abstract subjects here. The mosquito-borne diseases reported most often in Australia are Ross River virus infection, Barmah Forest virus infection, dengue fever (in northern Queensland and the Torres Strait), and malaria, usually in people who have travelled overseas. Recent data paints a concerning picture: national case numbers for mosquito-borne viruses nearly doubled between 2023 and 2024, with early 2025 data suggesting sustained transmission during the seasonal peak.
Climate change is likely to sharpen the problem. Research indicates that rising temperatures are expanding the habitat range of key vector species, meaning diseases once largely confined to the tropical north face the prospect of spreading further south. For communities in the Indo-Pacific, this is a shared regional challenge, not merely an Australian one.
The scientific response in Australia has been genuinely innovative. The World Mosquito Program has been deploying Wolbachia bacteria in Queensland mosquito populations since 2011. Far North Queensland is now essentially a dengue-free area for the first time in well over 100 years. That is a remarkable public health achievement, built on careful science and sustained community engagement, and it illustrates precisely the kind of relationship with blood-feeding creatures that the exhibition asks its visitors to consider: one based on understanding rather than pure revulsion.
Science, Culture, and the Cost of Disgust
There is a reasonable argument that exhibitions like this do more than entertain. Public understanding of vector biology is directly relevant to vaccination uptake, community participation in mosquito control programmes, and the political will to fund biosurveillance. When people understand why mosquitoes bite (female mosquitoes require blood to nourish their eggs, not for their own nutrition), they are better placed to engage with public health messages about prevention and control.
Critics of science museums sometimes question whether blockbuster touring shows, which arrive from wealthy Northern Hemisphere institutions and charge premium ticket prices, represent the best use of public cultural infrastructure. The concern is not trivial. Australia's museum sector relies on a blend of government funding and earned revenue, and there is a legitimate debate about whether international touring agreements serve local audiences and local scientists as well as they serve balance sheets. The Australian Museum's own researchers produce world-class natural history work, and a permanent exhibition drawing on that in-house expertise might carry deeper local resonance than a polished Canadian import.
That said, the counter-argument holds real force. Touring exhibitions bring production values that individual institutions would struggle to match alone, and they expose Australian audiences to international curatorial thinking. The Auckland War Memorial Museum ran the show to strong audiences from late 2024 into 2025, suggesting regional appetite is there. And if an exhibition about mosquitoes nudges even a fraction of its visitors to take dengue prevention more seriously, the public health dividend extends well beyond the gallery walls.
What the exhibition ultimately offers is an invitation to reconsider creatures that most of us would rather not think about at all. The science of blood-feeding is genuinely extraordinary: vampire bats are the only mammals that have successfully evolved to overcome all the hurdles of finding blood, extracting it, keeping it flowing, and storing it in the body. Leeches have been instruments of medicine for more than two millennia and remain in clinical use today for stimulating blood flow after microsurgery. Mosquitoes, for all the misery they cause, are central to the food webs that sustain ecosystems across the tropics. The creatures deserve our attention, even if they do not quite deserve our affection. The Australian Museum is betting that Sydney visitors will agree.
Bloodsuckers: Legends to Leeches is scheduled to open at the Australian Museum in Sydney later in 2026. Ticket and date details are expected to be announced through the museum's official channels.
