THE BUTTERFLIES OF CASCADIA covers every species and subspecies found in the Pacific Northwest, from southern B.C. to northern California and Nevada, from western Idaho to the Pacific, and all of Washington and Oregon. Virtually every species is illustrated by brilliant photographs from life, while the more difficult and variable groups also have color plates of comparative specimens and superb full-color drawings. Each scientific species account includes all the names the butterfly might be known by, field marks for recognition, variation and varieties, life history, caterpillar and adult food plants, flight period, habitat, range, and a distribution map. A second, familiar section presents history, lore etymologies, and esthetic encounters. Opening essays introduce the Cascadian Bioregion, along with butterfly ecology, conservation, study, and nomenclature. This book is for serious students, everyone who watches, collects, photographs, rears, or gardens for butterflies, and for everyone who simply enjoys having them around.
Skippers About thirty species of these black-and-white skippers occur in the world, mostly in the Northern Hemisphere with a few in the American tropics. In English-speaking Europe, they are known as grizzled skippers, and our Arctic Skipper ( Carterocephalus palaemon) is known as the Chequered Skipper. American species of P_yrgus have been called checkered skippers -for their obvious panern --at least since W. J. Holland referred ro them by that name in his 1898 Butterfly Book. N ABA spells it

After fourth-instar hibernation, pale green, white-striped larvae feed up, pupate, and yield the single generation of adults that nectar on composites and other flowers.

This corresponds with a conservative interpretation of the bioregion known as Cascadia -- all of Washington and O regon. and the bordering sections of southern British Columbia, western Idaho, and northernmost California and N evada. These days, many biologists, conservationists, and others have begun thinking of place in terms of ecologically meaningful, watershed-defined bioregions rather than expedient but ecologically arbitrary political units. This should enable planning and living

The Cascadian range extends from the North Cascades, Okanogan Highlands, and Selkirks of WA-BC south to abom Lake Wenatchee in WA; then absent until the Blue/Wallowa Mtns of WA-OR. and the OR Cascades S to Crater Lake. The dramatically pink wing fringes are sometimes visible in flight. Certain other Colias have pink fringes, but none is edged
recently discovered Leona's Little Blue. Blue-Wallowa Mountains: Occupying the southeastern corner of Washington and a larger area of northeastern Oregon, the Blue Mountains complex is largely basaltic and sedimentary with flattish tops mostly under 6,000 feet. The most prominent subrange, the Wallowas, runs down to the mile-deep Hell's Canyon at the Snake River, and up to 9,500 foot limestone and granitic peaks, glaciated into cirques and horns.
