I wanted to let everyone know that a very nice and affordable book is coming out dealing with freshwater invertebrates of North America (so put it on your wish list). The current authoritative freshwater invertebrate book by Pennak is very nice; however, I've been told a lot has changed in aquatic invertebrate taxonomy and so a new guide is much needed. Also the new guide is far cheaper than Pennak's and so you won't hurt the wallet as much when purchasing this book. Anyways, below is some information that will help you track it down so you can consider purchasing it.
Authors: James Thorp and Christopher Rogers
ISBN-10: 012381426X
ISBN-13: 978-0123814265
Publisher: Academic Press
Release Date: 11/15/2010
Title: Field Guide to Freshwater Invertebrates of North America
It's available for pre-order on Amazon and I'm sure it will become available on many other websites as we get closer to the release date.
Thanks to Dan Murrow for informing me about this book -- I thought some of you might be interested, so I'm spreading the word.
