Species Jadera haematoloma - Red-shouldered Bug


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.)
