Species Ptenothrix maculosa
The Cave Fauna of CaliforniaBy W.R. Elliott, J.R. Reddell, D.C. Rudolph, G.O. Graening, T.S. Briggs, D. Ubick, R.L. Aalbu, J. Krejca, S.J. Taylor

Hidden biodiversity is revealed in this study of California's subterranean fauna, which contains distinctive elements that differentiate it from other North American regions. Since 1975, the rate of discovery of new species has accelerated with funded projects in most of the important cave areas of the state, including our own studies. Here we compile all available biological records for subterranean sites in California dating back to 1840.
California's karst is primarily comprised of small outcrops of marble or limestone with thousands of caves. Additionally, lava and ash flows, tens of thousands of mines, hundreds of sea caves on the mainland coast and islands, and extensive groundwater systems provide habitat for subterranean life.

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).

A very good textbook for initial research and learning about insects. It lays a nice foundation.
