This is a thoroughly revised & updated version of the classic "California Insects" by Jerry A. Powell & Charles L. Hogue, originally published by UC Press in 1979.

Beyond updated names, additional taxa, and new information...a highlight of the book is the more than 700 illustrative photos...the vast majority exquisitely taken by BugGuide editor Joyce Gross (who besides curating the photos and overseeing their layout, contributed in many other ways large & small).
