Butterflies of British Columbia summarizes all available information on the butterflies of B.C. The 187 species and 264 subspecies of butterflies known from B.C., as well as 9 additional hypothetical species, are discussed with descriptions of identifying features, immature stages, larval foodplants, biology and life history, range and habitat, and conservation status. In addition, descriptions are provided for 11 new subspecies. Each species treatment also contains maps of the northwestern North American distribution, colour photographs of adults of all species and subspecies, and flight season graphs.
The book includes an extensive general introduction to the study of butterflies, containing chapters on the history of butterfly study in B.C., the post-glacial colonization of B.C. by butterflies, the effects of European colonization on the fauna, butterfly conservation, butterfly gardening, ecology, morphology, and biology.
Butterflies of British Columbia provides butterfly watchers, naturalists, and biologists with an overview of the fascinating butterfly fauna of B.C. and adjacent areas. It can be used by naturalists to identify all the butterfly species and subspecies in B.C. and adjacent areas and includes a wide range of information about both butterflies in general and individual species. There is also much original information in the book that scientists will find invaluable, especially the description of 11 new subspecies and a complete reassessment of the taxonomy of the species.
In this easy-to-use field guide, the Tvetens describe and illustrate more than 100 species of butterflies that live in Southeast Texas and can often be found across the state. Striking color photographs of living butterflies and caterpillars (a unique addition) show the key marks and characteristics necessary for field identification. The Tvetens' enjoyable and authoritative text describes each species' life history, habits, flight patterns, and characteristic markings.
An account of the different butterfly families, from swallowtails to longwings to skippers, precedes the descriptions of the species within each family. The Tvetens also include an interesting discussion of butterfly biology, a complete checklist of area butterflies, an index of butterfly-attracting plants, and pointers to other butterfly resources.
This field guide is the first to focus exclusively on Southeast Texas butterflies. It will be the essential reference for everyone seeking a reliable way to identify these butterflies, from field observers to apartment dwellers who wonder what is fluttering around the pot plants on the balcony.
The books starts with an introduction covering the author's collecting motivation plus observations on some of the amazing elements of butterfly life and behaviour. THe book takes the reader to six collecting areas selected on the basis of great butterflies and significant social events:
