Hammond Department of Zoology Oregon State University Corvallis, Oregon 97330-2907 FHTET-03-11 December 2003 i DEDICATION AND ACKNOWLEDGMENTS ACKNOWLEDGMENTS DEDICATED TO DOUG FERGUSON The following individuals provided their expertise in identifying adults reared from the field- collected caterpillars: Paul Hammond, Doug Ferguson, Jerry Powell, Don LaFontaine, Jim his book about Lepidoptera of Pacific Troubridge, Paul Opler, Jon Shepard, and Lars Crabo. The following people helped collect Northwest caterpillars and their adults is T and rear caterpillars: Paul Hanson, Jean Miller, Mike LaMana, Carolyn ver Linden, Dana Ross, dedicated to the late Doug Ferguson. Doug Norm Anderson, Jack Lattin, Maret Pajute, Gary Parsons, Emma Rossi, Pete Oboyski, and played a very important role in the conduct Rich Bowden. Dave McCorkle provided the photographs of caterpillars of Parnassius clodius, of our studies. He offered his expertise in Parnassius smintheus, Phyciodes pulchellus, and Atlides halesus. Rick Westcott took the photograph taxonomy, which was critical to the of the caterpillar of Catocala ilia. All other photographs were taken by the senior author, JCM. identification of many of our geometrid Chuck Benedict, INTECS International/USDA Forest Service, Forest Health Technology species, and encouraged us to keep up the Enterprise Team, deserves special thanks for shepherding the manuscript through to final sometimes arduous task of field collecting and draft and layout. Jean Miller spent many hours helping collect, rear, curate, and organize data rearing caterpillars from various foodplants. during the preparation of this manuscript. We will miss him. The Oregon Department of Agriculture, Plant Division, kindly provided specimens for photography, in particular we would like to thank Jim LaBonte, Kathleen Johnson, and Dan Hilburn. The Department of Botany and Plant Pathology at Oregon State University, specifically Scott Sundberg and Thea Cook, assisted us by loaning us parts to a digital scanner. Also, this booklet would not have been produced without the encouragement and support of Richard “Dick” Reardon and the USDA Forest Service, National Center of Forest Health Management, Morgantown, West Virginia. This is the sixth book in a series on the Lepidoptera of forests and woodlands. Dick has been the driving force and producer for the entire series. Those in the series written by senior author Dave Wagner covered the species of the northeastern United States, while those written by senior author Jeff Miller covered species of the Pacific Northwest. We are very grateful for the opportunity to produce this book, and extend our sincere thanks to Dick for his support. Partial funding was provided by NSF LTER grants in support of the H.J. Andrews Experimental Forest: DEB 80-12122, and DEB 96-32921; the USDA Forest Service Pacific Northwest Forest and Range Experiment Station, Willamette Institute for Biological Control, the USGS; and the Oregon State University College of Agricultural Sciences. LEPIDOPTERA OF THE PACIFIC NORTHWEST ii ABOUT THIS BOOK The subjects and their accompanying photographs of Lepidoptera are organized alphabetically by family and then by genus within the categories of butterflies, skippers, and moths. While many of the species illustrated here are common, only a small percentage of the species in the Northwest are represented. If the identity of a macromoth from the western United States cannot be determined by matching a specimen with a description or photo in this book then look in Miller and Hammond 2000 or Covell 1984. Covell 1984 provides an extensive assortment of photographs for species that occur in the eastern United States so the probability of a match to a western species is limited to those species that are widespread across the North American continent. Also, serious students of moths should look in the references following the discussion of all families in the section on macromoths. For each of the 239 species presented we provide a narrative that includes three sections: Caterpillar, Adult, and Ecology. The caterpillar and adult sections are descriptive for general identification purposes. The ecology section presents information on abundance, foodplants, seasonality, flight, and biogeography.
