Nick Haddad, "The Last Butterflies: A Scientist's Quest to Save a Rare and Vanishing Creature" (Princeton UP, 2019)

Butterflies have long captivated the imagination of humans, from naturalists to children to poets. Indeed it would be hard to imagine a world without butterflies. And yet their populations are declining at an alarming rate, to the extent that even the seemingly ubiquitous Monarch could conceivably go the way of the Passenger Pigeon. Many other, more obscure, butterfly species are already perilously close to extinction. For the last 20 years, Nick Haddad has worked to identify and save some of the rarest butterflies on earth, a quest that has taken him to both surprisingly ordinary and extraordinarily inhospitable areas, including a swampy, active artillery range on a military installation in North Carolina. It has also led him to some surprising conclusions about the best ways to protect these increasingly endangered butterflies. In The Last Butterflies: A Scientist’s Quest to Save a Rare and Vanishing Creature (Princeton UP, 2019), Haddad profiles five such species – the ones he has determined to be the rarest of all – and takes us into each one’s unique habitat, life cycle, and existential challenges. From the Crystal Skipper, bouncing over sand dunes adjacent to vacation homes on barrier islands, to the Schaus’ Swallowtail, confined to increasingly remote areas of the Florida Keys, Haddad shows how human activities have affected rare butterfly populations. His unexpected conclusion is that leaving them in peace is not a viable option; disturbances, both natural and human-caused, are necessary for the ecosystems that support butterfly populations to thrive. One of the hardest lessons for him to absorb was that to save populations, some individuals have to be killed in the process. Haddad’s intrepid field work – he describes one of his strengths as “an unusual capacity to tolerate harsh environments - informs the story of each butterfly species. His lab’s effort to collect, quantify, propagate, and ultimately perpetuate, the rarest butterflies has led to increasing awareness of how much more biologists have to l
