Heteroptera of Eastern North America

Great resource for true bugs of Eastern North America, although sorely out of date.

Catalog of the Heteroptera, or True Bugs of Canada and the Continental United States
By Thomas J. Henry, Richard C. Froeschner
Brill Academic Publishers, 1988
A thick book cataloging all 3834 North American species from 45 families. Things have probably changed some since 1988, but at almost 1000 pages there's lots of good info here. Mostly the species are just listed, but there are some illustrations and sometimes distribution info.

I wouldn't recommend paying the going used rate of over $100 for this, but I got lucky on a new copy off eBay for a good bit less than that.

If someone wants me to look something up for them in my copy, I'd be happy to do that. Just send me an email and be patient, it may take me a few days to get around t

Checklist of the Hemiptera of Canada and Alaska
By Maw, H.E.L., R.G. Foottit, K.G.A. Hamilton and G.G.E. Scudder
NRC Research Press, 2000
From the publisher's website:

All species of Hemiptera (including 'Homoptera') known to occur in Canada and Alaska are listed and distribution by major political division given. Arrangement is by taxonomic hierarchy with cross-references from alphabetic lists of genera and species. Annotations identify introduced species and indicate pest status. A brief descriptive synopsis is included for principle taxonomic groups and references to available identification guides (keys, revisions, handbooks), catalogues, and bibliographies is provided for genera and higher taxa.

How to Know the True Bugs
By Slater, James A., and Baranowski, Richard M.
Wm. C. Brown Company, 1978
Part of the Pictured Key Nature Series. This one is, as of this writing (2004), out-of-print and hard to find. Very useful, in that it illustrates all families and many genera of hemiptera. Widespread or notable species are described in each genus. Almost 500 illustrations.

(This book should be under Heteroptera--not Pterygota.)
