Take a look at "Aquatic Insects and their Imitations"
by Rick Hafele and Scott Roederer ( revised edition )
This book is a great read and reference.
It also is paper back and fits into your pack nicely
for on stream use. This book is a real hands on field guide written with us flyfishers in mind.

I also have and old college book titled
" An Introduction to the Study of Insects"
5th edition by Borror, DeLong, Triplehorn. Bit heavy but if your over the bank as I am you might want to get one like this some of the classifications have changed since this was published but still very good reference for amature study.
This one may be more than you need to own so check you library for this one...
I have more so if you are interested give me a shout
I love bugs....
Take care,
Steve Molcsan
ps: for colored pictures and beautful ones at that as well as emergence dates and times take a look at "Selective Trout"
by Doug Swisher and Carl Richards ,iustrated b by
Dave Whitlock, this one dose also cover some tying stuff also but well worth a review.
