Book Description
A thorough understanding of the mechanisms driving larger scale consequences of movement first requires an understanding of whether movement behaviors are related to local or landscape scale determinants. I studied the movement behaviors of four species of bottomland-dwelling butterflies in a natural setting to examine the determinants of movement behavior across different scales. Across spatial scales, I tested the relative importance and predictive value of three landscape attributes: topography, boundary contrast, and stream proximity, and two local habitat attributes: host plant cover and comprehensive vegetative structure. Across species, I tested the relative importance of organism size and habitat specificity to explain response variation. In general, butterfly responses to landscape features were stronger and more universal while responses to local features were weaker and more variable by species. Specifically, results from this study showed that topography does not influence movement behaviors but boundary contrast, stream proximity, and host plant abundance all contributed to movement patterns. Orientation to these features was not related to organism size, but did vary in accordance with habitat specificity. These results suggest that studies on dispersal in fragmented landscapes should consider the effects of that fragmentation on multiple scales. This consideration is particularly important in the management of rare species, when specific behaviors may ultimately affect the success of conservation efforts.

Book Description
Behavior is the means through which animals interact with the environment and with each other. As such, behavior must be central to conservation efforts. In no example is this more clear than with the large blue butterfly (Phengaris arion) in the United Kingdom: failure to understand its life history and species interactions led to its local extinction, even with habitat restoration efforts. Despite the clear importance of behavior, conservation behavior is often under-discussed even in situations where the natural history of a species is well understood. We propose exploring conservation behavior within insects, and doing so with a wide diversity of species and geographic locations. As insects have often served as models to advance theory, so they may serve as models to advance conservation. Our goals for this collection are three-fold. First, we aim to present the latest in insect behavior research, and how such research can be applied to conservation. Second, we will promote diverse authors from diverse geographic locations. Third, we will facilitate an educational/mentoring experience for early career professionals by enlisting senior professionals to work with their students and/or post-docs on the publication process from manuscript submission, to review, to publication.

Book Description
Hanski, a leading thinker in metapopulation ecology, studies checkerspot butterfly populations in Finland. Ehrlich, one of the leading ecologists and conservation biologist, investigates checkerspot butterfly populations in California. This book reports on and synthsizes the major long-term research of both workers' careers on the population biology of checkerspot butterflies.

Book Description
A remarkable look at the rarest butterflies, how global changes threaten their existence, and how we can bring them back from near-extinction Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender’s Blue? Or the St. Francis’ Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures—some numbering no more than what can be held in one hand. Drawing from his own first-hand experiences, Nick Haddad explores the challenges of tracking these vanishing butterflies, why they are disappearing, and why they are worth saving. He also provides startling insights into the effects of human activity and environmental change on the planet’s biodiversity. Weaving a vivid and personal narrative with ideas from ecology and conservation, Haddad illustrates the race against time to reverse the decline of six butterfly species. Many scientists mistakenly assume we fully understand butterflies’ natural histories. Yet, as with the Large Blue in England, we too often know too little and the conservation consequences are dire. Haddad argues that a hands-off approach is not effective and that in many instances, like for the Fender’s Blue and Bay Checkerspot, active and aggressive management is necessary. With deliberate conservation, rare butterflies can coexist with people, inhabit urban fringes, and, in the case of the St. Francis’ Satyr, even reside on bomb ranges and military land. Haddad shows that through the efforts to protect and restore butterflies, we might learn how to successfully confront conservation issues for all animals and plants. A moving account of extinction, recovery, and hope, The Last Butterflies demonstrates the great value of these beautiful insects to science, conservation, and people.

Book Description
For decades, bird watchers have delighted in the freedom and joy of nature armed only with binoculars and a good field guide. In more recent years, amateur naturalists have also turned their lenses to the world of butterflies, whose myriad species and fantastic shapes and colors offer an intriguing challenge to even the most seasoned birder. But while bird enthusiasts have always had the help of accurate and accessible handbooks, those observing butterflies have had no such advantage. Until now, that is.In this unique field guide, Jeffrey Glassberg has made butterfly watching a less frustrating and far more rewarding pastime, showing us how to find, identify, and enjoy the nearly 160 species that inhabit the Northeast. Butterflies Through Binoculars is the first butterfly guide to combine the immediacy and vividness of actual photographs of living butterflies with the traditional field guide format. While older guides cater to the collector, offering drawings that show the captured and mounted insect, this book shows butterflies in their natural poses and in the correct size relationship to related species. With Butterflies Through Binoculars in hand, the brilliant Tiger Swallowtail, the more dour Mourning Cloak, even the Rare Skipper itself will not elude identification by the beginning--or, for that matter, the more seasoned--observer. By focussing the guide on the Boston to Washington corridor, Glassberg has excluded the species from unrelated areas that have made older field guides so cumbersome. In addition, he provides entirely new field marks for butterfly identification, demonstrates how to identify subjects by way of the key characteristics butterflies are likely to display in their natural settings, shows how species can be recognized both from above and below, and explains how to differentiate between males and females.Besides being a handy guide to identification, Butterflies Through Binoculars also tells readers where to find particular species, giving a complete account of flight times, ranges, and seasonal patterns. Nine major locations for butterflying are described in great detail, and readers are directed to forty specific locations where uncommon--even rare--species can be found. And throughout the book, the basic natural history of each species is considered in a lively, readable fashion.For butterfly enthusiasts, for bird watchers who want to add a new dimension to their hobby, for anyone who is simply interested in exploring the wilds of their own back yard, Butterflies Through Binoculars will offer hours of delightful help and instruction.
