A. Pat McCafferty's book is a good one and I recommend it highly. I have not read the other two you mention so cannot comment on them.

However, I can provide a few references that may help you. Here they are:

1. Nymphs of North American Stonefly Genera (Plecoptera) by Kenneth W. Stewart and Bill P. Stark. Univ. of No. Texas Press, Denton, 1993. ISBN 0-929398-55-6

As the title indicates, it emphasizes the nymphs, rather than adults, but does present information on life histories, etc. It has excellent keys to the nymphs, but like any taxonomical reference, some of it becomes outdated as taxonomists continually revise the systematics, discover new species, etc. In fact, the last time I saw Ken, I think he told me that a new edition of this was either in preparation or just out. The memory starts to go when you get my age.

A sidenote: Ken gets a lot of kidding about being the only entomologist written up by Sports Illustrated. He discovered that male stoneflies "drum" to attract females; somehow, this piqued the interest of SI and they published a story about it.

The above is the only book specifically on stoneflies that I have in my library. The following references are broader in scope (but narrower in detail), although each contains information on stoneflies.

2. An Introduction to the Aquatic Insects of North America, 3rd ed. edited by R.W. Merritt and K.W. Cummins. Kendall/Hunt Publ. Co., 1996. ISBN 0-7872-1761-1

This is mainly a taxonomic reference although there is some information on biology, ecology, etc. of the different groups. Ken Stewart (see above) wrote the section on stoneflies. It is the most widely used general reference for insect taxonomy.

3. Aquatic Insect Ecology. 1. Biology and Habitat by J.V. Ward. John Wiley & Sons, Inc., 1992. ISBN 0-471-55007-8

A formal text covering many aspects of the biology and ecology of aquatic insects. James never did complete succeeding volumes, but this one has a lot of good information.

4. An Illustraed Guide to the Mountain Stream Insects of Colorado, 2nd ed by J.V. Ward, B.C. Kondratieff, and R.E. Zuellig. Univ. Press of Colorado, 2002. ISBN 0-87081-653-5

A small paperback with biological and ecological information on the fauna of Colorado streams; good illustrations and keys to genera.

5. Streams: Their Ecology and Life by C.E. Cushing and J.D. Allan. Academic Press, 2001. ISBN 0-12-050340-9

I saved the best to last! Seriously, we wrote this as a "textbook for layman" and it covers the entire aspect of stream ecology. There is a chapter on insects, with a section on stoneflies; most of the information was gleaned from the above references plus McCafferty's book.
