A Field Guide to Insects of the Pacific Northwest
Insects are all around us, from the butterflies in our gardens to the mosquitoes in the woods. About 80 percent of the 1.5 million named species of animals on earth are insects. Without flower-loving bees, wasps, flies and beetles, most crops and wild plants would not be pollinated and would disappear. But insect diversity is largely invisible because most insects are small and difficult to recognize and identify. They are often easy to ignore. A Field Guide to Insects of the Pacific Northwest is a durable, water-resistant eight-fold field guide that describes more than sixty of the most common species that are likely to be encountered in the many habitats of the Pacific Northwest. Full-colo...

Crossing Home Ground
Like John Muir, David Pitt-Brooke stepped out for a walk one morning—a long walk of a thousand kilometres or more through the arid valleys of southern interior British Columbia. He went in search of beauty and lost grace in a landscape that has seen decades of development and upheaval. In Crossing Home Ground he reports back, providing a day-by-day account of his journey’s experiences, from the practical challenges—dealing with blisters, rain and dehydration—to sublime moments of discovery and reconnection with the natural world. Through the course of this journey, Pitt-Brooke’s encounters with the natural world generate starting points for reflections on larger issues: the delicat...
Odonata Biology of Dragonflies
Dragonflies (Odonata), represented by over 6000 known species, are unique insects. In more than one feature they differ, at the very first glance, from all other insect superorders including their nearest allies, the mayflies (Ephemeropteroidea). The Zygoptera and Anisoptera, on the other hand, are the dominant groups. Being voracious predators in both immature (aquatic) and adult (aerial) stages they are important elements of all, except the drier (or high alpine) environments in temperate and tropical regions, occupying a position at the apex of the food chain of invertebrate life. Many dragonfly species are tested biological control agents for several disease-transmitting vector mosquitoe...

Dragonfly Nymphs of North America
This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 gen...
