Butterflies of the Sinlahekin Wildlife Area

This book describes and illustrates the 124 butterfly species of Okanogan County along with maps of the 92 species found on or near the Sinlahekin Wildlife Area in north-central Washington State. Although this book focuses on the Sinlahekin, only 31 of Washington's 155 butterfly species are not found in Okanogan County, making this book useful for much of the state. It also contains many helpful tips on identifying difficult species such as duskywings, blues and fritillaries. Published in 2017 14,314 acre Sinlahekin Wildlife Area (SWA).
